Gill Tract Final Status Survey Report
1.0 INTRODUCTION
On February 21, 2008 Bartlett Services, Inc. was contracted by the University of California at Berkeley (UCB) to develop and implement a Radiological Sampling and Analysis Plan (SAP) in order to ensure that decommissioned materials associated with the Gill Tract Hybridoma Center were identified and disposed of to licensed radioactive materials disposal facilities in accordance with California Executive Order D-62-02 and to perform a Final Status Survey on Open Land Areas associated with soils located around the Hybridoma Center and Gill Tract planting field.
Guidance on designing and implementing radiological surveys of building surfaces was taken from NUREG-1575, Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM). Guidance on designing and implementing radiological surveys of materials and equipment was taken from the draft supplement 1 to NUREG-1575, Multi-Agency Radiation Survey and Assessment of Materials and Equipment (MARSAME).
Radiological surveys of the Gill Tract site, owned by the UCB, have been completed in accordance with the California-approved SAP (Bartlett, 2008a). Materials suspected of containing residual levels of radioactivity in excess of the limits presented in Regulatory Guide 1.86 were removed and properly disposed of as radioactive waste. Radioactivity in excess of naturally occurring background levels has not been identified in the remaining Hybridoma Center or the planting field. This report documents the results of the radiological surveys in and around the Hybridoma Center and the planting field, and supports a decision that the Gill Tract site can be released for use without radiological restrictions.
Based on the results of the radiological surveys at Gill Tract and the associated reference areas, there is no dose above background at the Hybridoma Center or the planting field. The levels of radionuclides in surface soil in the planting area and the radionuclide concentrations in the area surrounding the Hybridoma Center are consistent with reference area concentrations and, under the resident farmer scenario, contribute an annual dose less than 1 mrem.
Based on the results of the final status surveys perfonned at Gill tract, the entire 10 acre property is recommended for release from radiological controls with no restrictions.

Gill Tract Final Status Survey Report
2.0 SITE BACKGROUND
In 1890 Edward Gill, an expert, world-renowned horticulturalist, purchased 104 acres and established the Gill Nursery. Mr. Gill became widely known for the antique roses cultivated at the nursery, some of which are still found in the Bay Area. At that time the property extended from what is now 1-80 to San Pablo A venue and from Codornices Creek to Buchanan Street. Although Edward Gill died in 1909, John Gill continued to farm on the land, until 1928 when the University of California (UC) purchased the nursery and resumed agricultural activities.
In 1939, the UCB gifted 5 acres to the United States Department of Agriculture (USDA) for the construction of what is now known as the Western Regional Research Center for the study of products that could be developed from agricultural commodities. In 1945, UC set aside 36 acres fronting on San Pablo Avenue and Buchanan Street, for an agricultural experimental station. This became the home of the northern branch of the University's Division of Biological Control, and later the site of the International Center for Biological Control. Projects pioneered at the Gill Tract included the ftrst major success in controlling weeds with insects in the United States. The Gill Tract became the center for this line of research in the United States in cooperation with the USDA. The Division is also credited with the control of numerous major insect pests on other California crops and pioneered in predator-prey population studies providing the groundwork for the eventual integration of biological, chemical and cultural methods of pest control.
In 1969, a portion of the land (adjacent to the present Ocean View Elementary School) was set aside for community gardens. The year 1969 was also the year that People's Park and Ohlone Park and Greenway were founded, which still exist and are widely recognized as having "kicked off' the modern day Ecology Movement by gaining worldwide recognition of the need for parks and open space in crowded urban areas. Today, community farming activities and experimental studies continue along Edward Gill Drive.
In 1995, the Division at the Gill Tract was joined with the College of Natural Resources, following which many of the research staff were transferred to the Berkeley campus. By 1997 the administration, funding and future of the station at Gill Tract became unclear and only recently has the University decided to develop the land for student and faculty housing, community activities and retail shops (ERS, 2008).
A radiological historical use assessment of Gill Tract (ERS, 2008) was conducted in June and July 2007 for the UCB. The Gill Tract is a University-owned 10-acre agricultural plot on San Pablo A venue. The tract was used for agricultural research and experimentation. As part of the research radioactive materials were used in trace amounts at one location within the Gill Tract called the Hybridoma Center.
Gill Tract is bordered by Buchanan Street to the north, San Pablo Avenue on the east, Monroe Street to the south, and Jackson Street/Eighth Street to the west. Figure 2.1 shows the major features of Gill Tract. Primary access to the site is from San Pablo Avenue, and Jackson Street provides a secondary entrance. Approximately 30 structures are located on the Gill Tract as shown in Figure 2.1. Gill Tract includes approximately 12 single story wood frame structures, 7 greenhouses, 7 large planting boxes, and 6 storage trailers. Use of radioactive materials at Gill Tract was officially terminated via a closeout survey performed by the Environmental Safety and Health (ES&H) group for UCB on January 22, 1997. No residual radioactivity was identified during the closeout survey. The majority of the structures at Gill Tract are abandoned.

Figure 2.1 Gill Tract Map
BARTLETT NUCLEAR, INC & CABRERA SERVICES, INC. Page3
Gill Tract Final Status Survey Report
Historical research has shown that the use of radioactive materials was limited to the Hybridoma Center. The Hybridoma Center includes a single story wood frame structure (approximately 1,300 ft2
), attached greenhouse (approximately 600 ft2), and detached wooden storage shed. The
wood frame structure housed a combination of offices and laboratories. Figure 2.2 shows the floor plan for the wood frame structure and greenhouse at the Hybridoma.
The results of the radiological use assessment indicate that use of radioactive materials was limited to laboratories 2, 617, 11 and the Culture Room (Room 3) located within the Hybridoma and the storage shed next to the greenhouse. However, sporadic indications of radioactive material in the hallways outside the laboratories were also noted. In addition, drains, sewage piping, and ventilation associated with hoods in the laboratories are considered impacted by the use of radiological materials at the Hybridoma Center. The radiological historical use assessment concluded that the laboratories 2, 6/7, 11, the Culture Room, and the drainage system for the Hybridoma would be considered Class 1 areas for closure. While no record of radioactive material use was found for the planting field in the northern portion of Gill Tract, this area was included as part of the final status survey because of the potential for plants impacted by radioactivity from the Hybridoma Center to be transplanted into the planting field could not be excluded.
Prior to performing the final status survey (FSS) for the Hybridoma Center in accordance with the SAP (Bartlett, 2008a), all trash and loose equipment were removed from the Hybridoma Center and the adjacent storage shed was demolished and disposed of as radioactive waste. All asbestos containing materials (including the floor tiles) and hazardous materials were removed from the building. At the time of the final status survey, the Hybridoma Center structure was clean of debris and the only items remaining to be surveyed were the structure itself, 2laboratory hoods (1 each in Room 617 and Room 11), and a built-in autoclave (Room 13).
BARTLETT NUCLEAR, INC & CABRERA SERVICES, INC. Page4
The survey design provided in the SAP (Bartlett, 2008a) used a graded approach to identify areas of potential residual radioactivity. In other words, additional survey effort was applied in areas more likely to have residual radioactivity.
3.1 Measurement Techniques
The primary measurement technique for the final status survey and reference area surveys was gross beta measurements. Field measurements for the Hybridoma Center were performed using the following detection instrumentation and techniques:
• Large area gas-proportional counter (e.g., 582 cm2 Ludlum Model 239-lF floor monitor with Ludlum Model 2224 scaler/ratemeter). Radiation surveys were performed in accordance with Procedure OP-001, Radiation Safety Procedure for Radiation Surveys, as described in the SAP (Bartlett 2008a).
• Hand-held gas-proportional counter (e.g., 100 cm2 Ludlum Model 43-68 gasproportional detector with Ludlum Model 2224 scaler/ratemeter). Radiation surveys were performed in accordance with Procedure OP-001, Radiation Safety Procedure for Radiation Surveys, as described in the SAP (Bartlett 2008a).
• Laboratory analysis of wet smears and solid samples using liquid scintillation techniques. All smear and solid samples analyses were performed by contracted independent laboratories using approved liquid scintillation counting protocols.
3.1.1 Gas Proportional Counter
There were two kinds of gas proportional counters used to perform radiological measurements at Gill Tract. The large area gas proportional detector has a large active area (e.~., 582 cm2
) while the hand-held gas proportional detector has a smaller active area (e.g., 126 em ). Both detectors were attached to a two channel (i.e., alpha and beta) scaler/ratemeter for performing scan or static measurements.
The large area gas proportional counter was used to perform scanning large, flat surfaces (e.g., floors) inside the Hybridoma Center and to perform static background measurements for reference material. The detector was connected to a ratemeter/scaler for performing individual static measurements and scanning large areas without recording individual measurement results.
The hand-held gas proportional detectors were used to perform scans and static measurements on walls, ceilings, and equipment inside the Hybridoma Center and to collect static background measurements for reference material.
3.1.2 Liquid Scintillation Counter
Liquid scintillation counting involves submersing or dissolving the sample directly in the liquid fluor. The liquid fluor reacts with the radioactivity in the sample to produce flashes of light proportional to the energy of the radiation. Liquid scintillation counting is particularly useful for measuring low-energy beta particles because problems relating to sample self-absorption, attenuation of particles by detector windows, and beta backscattering from the detector are completely avoided.
Wet swipes are optimum for collecting removable 3H contamination. The swipes were analyzed for tritium eH), carbon-14 (14C), and naturally occurring radionuclides. The liquid scintillation
BARTLETT NUCLEAR, INC & CABRERA SERVICES, INC. Page6
Gill Tract Final Status Survey Report
counter (LSC) was set to detect three ranges of beta particle energies. The low-energy channel was set to detect beta particles with low energies and was used to evaluate the potential presence of 3H (maximum beta energy of 18.6 keV) in the sample. The medium energy window was used to evaluate the potential presence of 14C (maximum beta patticle energy of 156 keV). The high energy window was used to evaluate the potential presence of other beta-emitting radionuclides with beta energies up to 2000 keV. All wet swipes collected in FSS areas were analyzed by subcontracted independent laboratories using approved liquid scintillation counting teclmiques.
Samples of solid materials were also evaluated using liquid scintillation counting. Approximately one gram aliquots of samples were processed to convert 3H to water and 14C to carbon dioxide. Water from the sample, including the 3H, was collected and counted using an LSC. Carbon dioxide from the sample was also collected and counted separately using an LSC. Tritium and 14C concentrations in the sample were calculated and reported based on these measurements.
3.2 Wet Smears
Removable tritium and 14C can be reliably detected at low concentrations using wet smears. Ten smears were collected from each survey unit in the Hybridoma Center. Wet smears were collected at the same locations where static measurements were performed. In addition, wet smears were collected at drain line connections to sewer pipes.
In general filter paper was used to collect the wet smears. However, cotton swabs were used for evaluating the inside of the vacuum lines because the inside of the vacuum lines was too small for filter paper. The smears were soaked in laboratory grade deionized water, and moderate pressure was used to collect a sample over an area of 100 cm2
. The cotton swab smears collected in this manner were then immediately placed inside a 20 milliliter glass scintillation vial. When the smears arrived at the contracted radiochemical analysis laboratory, scintmation cocktail was added directly to the vial containing the smear. As with all LSC samples analyzed by the contracted laboratory, the prepared samples were dark adapted for at least one hour ptior to counting to account for photochemiluminescence.
3.3 Surface Soil Samples
Surface soil samples were collected from random locations in the Gill Tract planting field, the outdoor areas immediately adjacent to the Hybridoma Center, and several reference areas identified by UCB. All soil samples were collected in accordance with Procedure OP-005 (refer to the SAP (Bartlett 2008a)). Custody and control of the soil samples were established and maintained in accordance with Procedure OP-008 (refer to the SAP (Bartlett 2008a)) and the Supplemental Sampling and Analysis Plan (provided as Attachment D). All soil samples were analyzed for 14C and 3H by contracted independent laboratories.
3.4 Other Samples
3.4.1 Vacuum Pump Oil
One oil sample not described in the SAP (Bartlett, 2008) was collected as part of the final status survey. This sample was collected to evaluate the potential for radionuclides in the vacuum system.
BARTLETT NUCLEAR, INC & CABRERA SERVICES, INC. Page7
Gill Tract Final Status Survey Report
3.4.2 Wood Shed
The detached wooden shed adjacent to the Hybridoma Center was demolished and packaged for disposal because it was not practical to survey the porous wood used to construct the shed. A sample of oil was collected from the vacuum pump and sent to an offsite laboratory and analyzed for the presence of 3H and 14C.
3.5 Material Reference Areas
The reference area survey provided information on the background distribution of radioactivity associated with each of the materials identified in Gill Tract. The information from background measurements was used to determine the natural radioactivity levels in the different media types being surveyed at Gill Tract. The field measurement techniques used to collect data for the final status surveys were also used to collect reference area data.
Materials expected to include inherent radioactivity had at least three reference areas. The reference areas were selected from similar buildings at Gill Tract where there is no record of radioactive materials being used. A minimum of 15 one minute static measurements were performed in each reference area for each instrument used during the Gill Tract final status survey.
Materials that were not expected to include any inherent radioactivity had data collected from at least one reference area. Because all of these materials are expected to have a background close to zero, the instrument variability defined the distribution for all of these materials. Materials that were not expected to contain inherent radiation included metal, wood, drywall, glass, vinyl, and plastics. A single reference area in one of the wood frame structures at Gill tract was selected to represent background for materials other than concrete at Gill Tract. A minimum of 15 two minute static measurements were performed for each instrument used during the Gill Tract final status survey.
3.6 Class 1 Final Status Surveys
Class 1 areas had the highest potential for residual radioactivity and may exceed acceptance criteria. Following the graded approach, these survey areas received the greatest level of survey effort. Areas, materials, or equipment where historic spills or contamination were likely to have occurred were classified as Class 1 survey areas. Information from the Radiological Historical Use Assessment (RUA) (ERS 2008) was considered in classification of survey areas.
One hundred percent of all Class 1 areas, materials, and equipment were scanned for radiation. In addition, a minimum of 10 one-minute static measurements and 10 wet smears were collected in each Class 1 survey unit. Sample locations were selected in accordance with the Multi Agency Radiological Site Survey Investigation Manual (MARSSIM) guidelines (NUREG-1575), based on a random-start systematic triangular grid, and identified using Visual Sample Plan software.
Biased measurements were performed and wet smears were collected at locations based on scan results and professional judgment to evaluate areas of concern. Any area where radiation was detected by a scan measurement was cleaned using standard decontamination methods (i.e., soap and water) or removed and disposed of as radioactive waste. Areas of concern included sinks, drains, hoods, and entrances to hood exhaust ducts. Sections of drain lines for laboratory sinks that could not be surveyed were removed and disposed of as radioactive waste.
BARTLETT NUCLEAR, INC & CABRERA SERVICES, INC. Page 8
Gill Tract Final Status Survey Report
Class 1 areas at Gill Tract included the floors in laboratories 2, 617 (including the laboratory hood), 11 (including the laboratory hood), the Culture Room (Room 3), and the floor of the hallway inside the Hybridoma Center.
The detached wooden shed adjacent to the Hybridoma Center was also identified as a Class 1 area. However, it was determined that the building materials for the shed could not be adequately surveyed in a cost-effective manner due to the porous nature of the wood used in its construction. The shed was disassembled, sampled for waste characterization purposes, and the entire shed was disposed of as radioactive waste.
With the exception for the wood shed, no Class 1 survey units were located outside the Hybridoma Center.
3.7 Class 2 Final Status Surveys
Class 2 areas had a lower potential for exceeding residual radioactivity acceptance criteria than Class 1. Class 2 survey units received a lower level scanning effort. However, the number of static measurements (based on a random-start systematic triangular grid) was the same as that for a Class 1 survey unit. A minimum of 25% of all Class 2 areas were scanned for radiation. Scanned surfaces were selected based on professional judgment to include areas with the highest potential for residual radioactivity (e.g., window sills, shelves, walls behind large pieces of equipment).
A minimum of 10 one minute static measurements and 10 wet smears were collected in Class 2 survey units. Measurement locations were determined through use of a random-start systematic triangular grid in accordance with MARSSIM guidance (NUREG-1575) and identified using Visual Sample Plan software.
Biased measurements were performed and wet smears collected at locations selected based on scan results and professional judgment to evaluate areas of concern.
Class 2 areas at Gill Tract included the walls and ceilings in laboratories 2, 617, 11, and the Culture Room (Room 3) inside the Hybridoma Center. No Class 2 survey units were located outside the Hybridoma Center.
3.8 Class 3 Final Status Surveys
Class 3 areas have the lowest potential for residual radioactivity. Areas and materials at the Gill Tract site where there was no historical evidence of radionuclide use were classified as Class 3.
A minimum of 10% of floors and working surfaces in the Class 3 survey units inside the Hybrydoma Center were scanned for radioactivity. The scanned surfaces were selected based on professional judgment to include areas with the highest potential for residual radioactivity (e.g., window sills, shelves, areas around floor drains, and walls behind large pieces of equipment).
Class 3 survey units inside the Hybridoma Center had a minimum of 10 one minute static measurements performed and 10 wet smears collected from random locations. For outdoor Class 3 areas, a minimum of 10 surface soil samples were collected from random locations. Random sample locations were selected in accordance with MARSSIM guidance and identified using Visual Sample Plan software. Soil samples from locations covered with asphalt were collected from the soil immediately beneath the asphalt.
BARTLETT NUCLEAR, INC & CABRERA SERVICES, INC. Page9
Gill Tract Final Status Survey Report
Biased measurements were performed and wet smears collected at locations selected based on scan results and professional judgment to evaluate areas of concern. Areas of concern for Class 3 areas included the inside of sewer pipes connected to the Hybridoma Center and the hood exhaust vents on the roof of the Hybridoma Center.
Class 3 areas at Gill Tract include the non-laboratory areas inside the Hybridoma Center (i.e., offices and bathroom), the attached greenhouse, the outdoor areas in the immediate vicinity of the Hybridoma Center, and the planting field.
3.9 Survey Units
3.9.1 Building Surfaces
There were five Class 1 survey units, four Class 2 survey units, and four Class 3 survey units.
The floors areas of laboratories 2 and 3, the combined contiguous floor areas of laboratories 6 and 7, the floor area of laboratory 11, and the hallway floor comprised the Class 1 building surface survey units.
The walls and ceilings of laboratories 2, 3, 6 and 7 (combined as a single survey unit), and laboratory 11 comprised the Class 2 building surface survey units.
Rooms 1, 4, 5, 8, 9, 10, 12, 13, 14, 15 were combined into one Class 3 building surface survey unit and the attached greenhouse (shown in Figure 2.2 as rooms 16A and 16B) were combined into another Class 3 unit.
3.9.2 Open Land Areas
The immediate outside area around the Hybridoma Center and the planting field were separate Class 3 open land area survey units.

Gill Tract Final Status Survey Report
4.0 ACCEPTANCE CRITERIA
Regulatory Guide 1.86, Termination of Operating Licenses for Nuclear Reactors (NRC, 1974), provides a table of acceptable surface contamination levels. The limits for beta-gamma emitting radionuclides, including 14C, are 5,000 dpm/100 cm2 averaged over areas not more than 1 m2
,
and a maximum of 15,000 dpm/100 em for areas less than 100 cm2. The measured residual
surface contamination level (in units of dpm/100 cm2) is determined by accounting for
background radiation, detector efficiency, and appropriate geometric factors associated with the instrumentation. Regulatory Guide 1.86 does not address 3H surface contamination limits.
Regulatory Guide 1.86 limiting values are consistent with guidelines from IPM-88-2 "Policy Memorandum on Clearance Inspection & Survey," December 1, 1997 and Decon-1 "Guidelines for Decontamination of Facilities and Equipment prior to Release for Unrestricted Use," June 1977 which adopts the surface contamination guidelines of Regulatory Guide 1.86.
Although not a regulatory driver, U.S. Department of Energy (DOE) Order 5400.5, Radiation Protection of the Public and the Environment (DOE, 1995), provides a table of allowable total residual surface activity. The limits for beta-gamma emitting radionuclides are exactly the same as those listed in Regulatory Guide 1.86 except it provides a limit of 10,000 dpm/100 cm2 for removable 3H. DOE states that removable levels of 3H below this limit are acceptable to ensure that non-removable and residual fractions of 3H on surfaces will not exceed DOE dose limits and constraints.
The acceptance criteria used to evaluate the results of the radiological survey on building surfaces and equipment are the beta-gamma limits of 5,000115,000 dpm/100 cm2 for surface contamination from Regulatory Guide 1.86 for scanning and static measurements, and the 3H removable activity limits of 10,000 dpm/100 cm2 from DOE Order 5400.5 for wet smears.
The acceptance criteria for concentrations of 3H and 14C in soil are 4 pCi/g and 0.5 pCi/g, respectively. These concentrations correspond to 1 mrem/y total effective dose equivalent (TEDE) using the Nuclear Regulatory Commission (NRC) soil screening values from the Federal Register, December 7, 1999. The NRC soil screening values are conservative criteria for the Gill Tract site because they were derived using the resident farmer scenario, which assumes several exposure pathways (e.g., milk, meat, and fish ingestion, on-site well as drinking water source) that, in reality, do not exist at the Gill Tract site.
Measurement sensitivity was determined by calculating the minimum detectable concentration (MDC) for scanning, static, and smear measurements as described in the SAP (Bartlett 2008a). An MDC value was calculated for each instrument and measurement technique implemented during the FSS for the Gill Tract site. The MDC is the concentration that a specific instrument and technique can be expected to detect 95% of the time under actual conditions of use. The methodology for determining scan and static MDC values assumed a Type I error rate of 0.05 and a Type II error rate of 0.05.
4.1 Beta Scan MDC for Building Surfaces
The MDC for scanning building surfaces, materials, and equipment was calculated using the following equation as described in Section 4.5.1 of the SAP (Bartlett 2008a):
BARTLETT NUCLEAR, INC & CABRERA SERVICES, INC. Page 11
Gill Tract Final Status Survey Report
(60/ i)( 2.48) -Jb: MDCscan= C
-v p E1 (A/100)
where:
MDCscan = minimum detectable concentration for scanning surfaces (dpm/100 cm2)
2.48 = scan performance criteria (see Section 4.5.1 in the SAP (Bartlett 2008a))
bi = number of background counts observed in time interval I (270 cpm or 4.5 cps for Ludlum 43-69 and 539 cpm or 9 cps for Ludlum 239-1F)
p = surveyor efficiency, 0.7 (see Section 4.5.1 in the SAP (Bartlett 2008a))
Et = total efficiency ( c/d) and includes surface and instrument efficiency (0.0925 for low energy beta)
A = area of detector (126 cm2 for Ludlum 43-68 and 584 cm2 for Ludlum 239-1F)
= time interval of observation while detector passes over the source (for the Ludlum 43-68 detector, i = 2.9 seconds; for the Ludlum 239-1F, i = 5.3 seconds)
For example, the scan MDC for 14C on concrete using a Ludlum Model 43-68 handheld gas proportional detector was calculated to be 1,901 dpm/100 cm2 and 564 dpm/100 cm2 for the Ludlum Model 239-1F detector.
4.2 Beta Static MDC for Structure Surfaces
The MDC for static measurements will be calculated using the following equation as described in Section 4.5.2 of the SAP (Bartlett 2008a):
where:
3 + (4.65)-JB MDCsraric = Er (A/100) t
MDCstatic = minimum detectable concentration for static counting (dpm/100 cm2)
B = number of background counts during measurement time interval t (270 cpm)
E1 = total efficiency (c/d) and includes surface and instrument efficiency (0.0925 for low energy beta)
A = area of detector (126 cm2 for Ludlum 43-68)
t = measurement counting time interval (minutes)
For example, the MDC for 14C on concrete using a Ludlum Model 43-68 handheld gas proportional detector was calculated to be 681 dpm/100 cm2

4.3 Liquid Scintillation Counter MDC
As described in Section 4.5.3 of the SAP (Bartlett 2008a), the MDC for laboratory samples is similar to the MDC calculation for static measurements. The difference is that the wipes being analyzed represent removable contamination only. Wet smears were taken over an area of 100 cm2 using moderate pressure. The MDC equation for smears becomes:
BARTLETT NUCLEAR, INC & CABRERA SERVICES, INC. Page 12

where:
MDC

MDC= 3 + 4.65Jb Et
= minimum detectable concentration for static counting (dpm/100 cm2)
= number of background counts eH = 1.33 cpm, 14C = 2.46 cpm, and Channel C = 13.13 cpm)
Ei = detector 4n efficiency (eH = 26.5%, 14C =50%, and Channel C = 80%))
The background count rate and total efficiency for the smear LSC analysis are based on 3H measurements performed as part of the Gill Tract survey. The final MDC for the 3 LSC channels are as follows: 3H = 31.6 dpm/100cm2
, 14C = 20.6 dpm I 100cm2
, and Channel C = 24.8 dpm/100cm2
. The MDC calculations focus on the sensitivity of the LSC method and do not account for smear efficiency.
The MDC for solid samples is based on the action levels for solid samples. The required MDC for the laboratory is set equal to the action levels for 3H and 14C, 4 pCi/g and 0.5 pCi/g respectively.

5.0 SURVEY RESULTS
Following implementation of the survey design described in the SAP (Bartlett, 2008a), the survey results were reviewed, evaluated, and compared to the acceptance criterion described in Section 4.0. No areas with detectable residual levels of radioactivity in excess of the acceptance criterion were identified during these surveys.
5.1 Floor Monitor Scanning Results
Scanning surveys of large horizontal surfaces were performed in all areas of the wood frame structure in the Hybridoma Center. The floor monitor (Ludlum Model 239-1F gas proportional detector connected to a Ludlum Model 2224-1 ratemeter/scaler) was used to scan 100% of the floors inside the Hybridoma Center and the greenhouse.
An action level for scanning was calculated based on the background measurements from reference materials. The minimum detectable count rate (MDCR) above the average background for the reference material was used as an action level while performing the scanning survey (i.e., MDCR for floor= 242 cpm; MDCR for bare concrete= 255 cpm). No areas of elevated beta activity were detected on any of the floors.
5.2 Hand Held Scanning Results
Scanning surveys with hand held gas proportional detectors (Ludlum Model 43-68 gas proportional detector connected to a Ludlum Model 2224-1 ratemeter/scaler) were performed on at least 25% of the Class 2 areas and at least 10% of the surface area in the Class 3 units inside the Hybridoma Center. The scan MDC for the hand held surveys (1,901 dpm/100 cm2
) was sufficient to demonstrate that the Ludlum 43-68 could meet the acceptance criterion value of 5,000 dpm/100 cm2
. Scan surveys performed with hand-held instruments were compared to an action level based on the reference area data. The MDCR above the average background for the reference material was used as an action level while performing the scanning survey ((i.e., MDCR for floor = 170 cpm; MDCR for bare concrete = 185 cpm; MDCR for other surfaces = 149 cpm). No areas of elevated beta activity were identified by the hand held scanning surveys.
5.3 Hand Held Static Measurement Results
Static measurements with hand held gas proportional detectors (Ludlum Model 43-68 gas proportional detector connected to a Ludlum Model 2224-1 ratemeter/scaler) were performed in each survey area. All static measurements were 1-minute counts directly on the surface being measured. Table 1 presents a summary of the static measurements by survey unit. Maps of static measurement locations are provided in Attachment A, Sampling Locations. The static measurement data are provided in Attachment B, Survey Data.
A total of 135 static measurements for gross beta activity were performed in the wood frame structure and greenhouse in the Hybridoma Center. None of the results exceeded the acceptance criteria.
A total of 102 static measurements were performed in the Class 1 and Class 2 laboratories. These areas included the floors, walls, and ceilings in laboratories 2, 6/7 (including the hood), 11 (including the hood), 3 (Culture Room, Refrigerator). Static measurements on floors, walls, and ceilings were performed at predetermined locations, while static measurements on the hoods were performed at locations likely to contain elevated radioactivity. Random start systematic triangular grid locations were identified using the Visual Sample Plan software version 5.3.1.
BARTLETT NUCLEAR, INC & CABRERA SERVICES, INC. Page 14
Gill Tract Final Status Survey Report
A total of 11 static measurements were performed on the floor of the hallway (refer to Table 1 for a summary and Figure A-16 for locations) in the Hybridoma structure. Static measurements were performed at locations on a random start triangular grid. The locations were identified using the Visual Sample Plan software. The static measurement results were evaluated using the background for floor where tile had been removed. None of the static measurements on the floor in the hallway exceeded the acceptance criteria.
Thirty four static measurements were performed on the floors where tile had been removed, 26 static measurements were performed on walls, 10 static measurements were performed on the ceilings, 10 static measurements were performed inside the refrigerator (6 on the floor and 4 on the walls), and 22 static measurements were performed on the laboratory hoods and ductwork. The laboratory hoods had static measurements performed in the cabinet base, on all of the interior surfaces, inside the ductwork where it attached to the hood, and where it exhausted on the roof. A man lift was used to access the hood exhaust vent on the roof of the wood frame structure. Static measurements on the floor were evaluated using the floor background where tile had been removed. All other measurements were evaluated against the material/detector specific values. None of the static measurements in the laboratories exceeded the acceptance criteria.
A total of 12 static measurements were performed in the Class 3 areas inside the Hybridoma Center. These areas included Rooms 1, 4, 5, 8, 9 (rest room), 10, 12 (storage), 13 (autoclave room and inner greenhouse entrance), 14 (small mechanical room), and 15 (large mechanical room and outer greenhouse entrance). One static measurement was performed in each room at a random location, which was selected using Visual Sample Plan software. One static measurement was performed at the drain located beneath the autoclave in Room 13, and one static measurement was performed in the doorway between Room 15 and the outer greenhouse. The high traffic path through this doorway had worn away the floor covering exposing a small area of bare concrete with a slightly higher beta count rate than the rest of the floor. The biased measurement in Room 15 was evaluated using the bare concrete background while all other Class 3 static measurements were evaluated using the background for floor where tile had been removed. None of the static measurements in the Class 3 areas exceeded the acceptance criteria.
Using a hand-held gas proportional detector, a total of 10 static measurements were collected from the concrete floor in the greenhouse. Static measurements were performed at locations on a random start triangular grid. The locations were identified using the Visual Sample Plan software. The static measurement results were evaluated using the background for bare concrete. None of the static measurements on the floor in the greenhouse exceeded the acceptance criteria.
5.4 Wet Smear Results
Wet smears were collected in the wood frame structure and greenhouse at the Hybridoma Center at every location where a static measurement was performed and at 11 additional locations where static measurements could not be performed (i.e., inside drains and pipes). The 3 H and 14C analysis results for the wet smears are summarized respectively in Tables 2A and 2B.
Of the 11 additional smears that were collected, four were collected in and outside of laboratory 6/7: 1 in the trap for a sink used for disposal of radioactive waste, 1 at the entrance to the PVC pipe, 1 at the end of the PVC pipe, and 1 at the entrance to the iron sewer pipe. Two additional wet smears were collected outside laboratory 2: 1 at the end of the PVC pipe from laboratory 11 and 1 at the entrance to the iron sewer pipe. Two additional wet smears were collected outside Room 5: 1 where the iron sewer pipe left the building and 1 at the entrance to the sewer line.
BARTLETT NUCLEAR, INC & CABRERA SERVICES, INC. Page 15
Gill Tract Final Status Survey Report
One additional wet smear was collected from the drain in the custodial sink in Room 17. These nine wet smears were collected using cotton swabs instead of filter papers because of the limited access to the inside of the pipes and drains. Finally, two additional wet smears were collected from the greenhouse: 1 from the gutter outside the greenhouse (south end facing the paved courtyard) and 1 from the glass plates on the ceiling inside the greenhouse at the same location.
Wet smears were sent to a contracted commercial radiochemistry laboratory for analysis using liquid scintillation. A total of 146 wet smears were collected from the wood frame structure and greenhouse and analyzed for gross beta activity.
All of the wet smear results were below the MDC of 31.6 dpmJlOO cm for 3H (3H window) and below the MDC of 20.6 dpmIlOO cm 2 for 14C ( 14C window). A summary of the swipe results for 3H and 14C can be found in Tables 2A and 213, respectively. Maps of smear locations are found in Attachment A, Sampling Locations. Smear measurement data are provided in Attachment B, Survey Data
5.5 Soil Sample Results
Surface soil samples were collected from random locations in the Gill Tract planting field, the outdoor areas immediately adjacent to the Hybridoma Center, and several reference areas recommended by UCB.
The Gill Tract planting field was initially sampled in March 2008. Fifteen (15) soil samples were collected in accordance to the SAP (Bartlett 2008a), transported to Eberline Services in nearby Richmond, CA, and analyzed for 14C and 3H. The analytical results for those samples are shown in Table 3A.
The measured 3H concentration in each of the initial 15 soil samples from the planting field was below the MDC achieved during the analysis, indicating that any potential radiological impact to a member of the public from residual 3H in the planting field soil, if present, would be very small. However, the measured 14C concentration in each of the 15 samples exceeded the acceptance criterion for ’4C (i.e., 0.5 pCilg), which corresponded to an annual dose of 1 mrem under the resident farmer scenario. The measured 14 C concentrations ranged from 1.95 pCi/g to 34.9 pCi/g (the maximum concentration was observed in sample FSS-010). Because the 14C results for sample FSS-010 were so high relative to all the other sample results, a confirmatory analysis was requested. The second analysis of sample FSS-010 performed by Eberline Services indicated that the 14C concentration was approximately a factor of ten lower than the original results, but still greater than the ’4C acceptance criterion.
In August 2008, the FSS for the Hybridoma Center and the immediate outside area was conducted. Ten (10) soil samples were collected at random locations in immediate outside area of the Hybridoma Center. The soil sample locations are shown in Figure 5.1. Because it was necessary to punch through asphalt in order to collect several soil samples in the immediately area outside the Hybridoma Center, the top 6 inches of soil were collected from a 4-inch diameter area and placed in a steel bowl. Rocks or foreign material (e.g., glass, wood, stones, asphalt chips) larger than ’/4 inch were removed from the sample. Approximately 100 grams of soil were transferred to a re-sealable plastic bag. The bag was labeled with the sample information and sent to an offsite laboratory and analyzed for the presence of 3H and 14C. In addition, 1 sample of sediment from the gutter along the southeast edge of the greenhouse at the Hybridoma Center and 10 soil samples from 3 reference areas near the Gill Tract were collected.
BARTLETT NUCLEAR, INC & CABRERA SERVICES, INC. Page 16
Gill Tract Final Status Survey Report
All samples were transport to Eberline Services in Richmond, CA, for 3H and 14C analyses. The results for these samples are provided in Table 3B.
With the exception of 1 soil sample (S0-03), the measured 14C concentrations in the soil samples from the immediate outside areas of the Hybridoma Center were below the MDCs achieved during ’ 4C analyses, although the achieved MDC values were greater than the ’ 4C acceptance criterion. The measured 14C concentration in sample S0-03 was 16.58 pCi/g. Because of the previous laboratory error with soil sample FSS-010, a second 14C analysis for sample S0-03 was requested. The results for that second analysis indicated that the 14C concentration in the sample was non-detectable (i.e., below an MDC of 1.06 pCi/g). To resolve the conflicting results, sample S0-03 was sent to the Areva Environmental Laboratory for ’ 4C analysis. The Areva results confirmed the second analysis by Eberline; that is, that the 14C concentration in sample SO-03 was non-detectable (the MDC in the Areva analysis was 0.4 pCi/g, which was below the 14C acceptance criterion).
The Eberline analysis results also indicated that the 14C concentration in 2 reference area samples (samples RA-03 and RA-05) exceeded the MDC values as well as the ’ 4C acceptance criterion (0.5 pCi/g). As done for soil sample S0-03, these 2 samples were sent to the Areva Environmental Laboratory for ’ 4C analyses in order to confirm the Eberline results. The Areva results (presented in Table 3B) indicated that the 14C concentrations in the samples RA-03 and RA-05 were below an MDC value equal to 0.38 pCi/g, which was below the ’ 4C acceptance criterion. Because of the relatively high MDC values achieved in the Eberline 14C analyses and the conflicting laboratory analyses, confidence in the ’ 4C data from Eberline Services eroded.
As a result of the eroded confidence in the 14C data, a decision was made in the first quarter of 2009 to conduct another soil sampling effort for the Gill Tract site. A supplemental sampling and analysis plan (SAP) was developed and implemented in April 2009. A copy of the supplemental SAP is provided as Attachment D to this report. The supplemental SAP called for the collection of 20 random soil samples from the Gill Tract Planting Field, 20 random soil samples from reference areas identified by UCB, and 13 soil samples from biased locations at or near the Gill Tract site. The soil sampling locations in the Gill Tract planting field are shown in Figure 5.2. All samples were collected and handled in accordance to directions in the supplemental SAP. Three independent laboratories were contracted to perform the 14C and 3H analyses. The primary laboratory was the Areva Environmental Laboratory in Westboro, MA. Eberline Services in Richmond, CA, and GEL Laboratories in Charleston, SC, performed 14C and 3H analyses on 6 split samples for quality control/quality assurance (QC/QA) purposes.
The ’ 4C and 3H results from the planting field samples, Reference Area samples, and the Gill Tract biased samples are presented, respectively, in Tables 3C, 3D, and 3E.
The 14C concentrations in all soil samples collected during the supplemental effort were found to be below the MDC value in each analysis. For 14C, the achieved MDC values were less than or equal to the 14C acceptance criterion (i.e., :50.5 pCi.g) in the Areva analyses. The analyses of the QC split samples by GEL Laboratories were within 15% of the 14C acceptance criterion and supported the Areva results. The Eberline 14C analyses results for the QC split samples were approximately a factor of 2 higher than the ’ 4C acceptance criterion and therefore could not be used as confirmation of the ’ 4C measurements.
For 3 H, the achieved MDC values were significantly below the 3H acceptance criterion (i.e., 4.0 pCi/g) in the analyses performed by all 3 laboratories. Eberline Services identified detectable 3H
BARTLETT NUCLEAR, INC & CABRERA SERVICES, INC. Page 17
Gill Tract Final Status Survey Report
in 2 of the split samples from the planting field (split soil samples OOL-01-013-F and 001-01-018-F). However, the Areva Environmental Laboratory and GEL Laboratories analyses for these 2 samples indicated that the 3H concentrations were below the MDC values (refer to results presented in Table 3C). Because both the Areva Environmental Laboratory and GEL Laboratories had similar "non-detectable" 3H results for soil samples OOL-01-013-F and 001-01-018-F, the positive results in the Eberline analyses are not considered to be an indication of sample activity.
The results of the ’ 4C and 3H analyses for soil samples collected at the Gill Tract site during the April 2009 sampling effort provide assurance that there is no detectable 14C or 3 H activity in soil as a result of the agricultural research conducted in the Hybridoma Center.
5.6 Other Sample Results
Three samples were collected as part of the final status survey at Gill Tract as discussed in Section 3.7; 2 samples from the shed for waste characterization and 1 oil sample from the vacuum pump in the courtyard. The three samples were analyzed for 3 H and 14C activity and counted using liquid scintillation. No 3 H or ’ 4C activity was detected in any of the samples. The results of the sample analyses are provided in Table 4.

5.7 Reference Data Results
Reference data were collected to provide information on background radiation for the hand held gas proportional detector and the floor monitor used to perform the final status survey. Reference data were collected for three types of materials; floors, bare concrete, and all other materials. Other materials included bench tops, drywall, and metal that were present in the Hybridoma Center. The reference areas for the hand held detector floors and other materials were located in the office located near the Jackson Avenue entrance to Gill Tract, while the bare concrete reference area was located in the restroom. The floor and bare concrete reference areas for the floor monitor were located on the concrete pad of a wood frame structure that had burned at Gill Tract leaving the concrete floors in a condition similar to the floors in the Hybridoma Center. The results of the reference area surveys are summarized in Tables 5, 6, and 7.
The ’ 4C and 3H results for soil samples collected from reference areas are presented in Table 313 and 3C.

’ Analyses performed between 6/1/09 to 6/15/09. In order to quantify ’ 4C and 3H, a purified solution obtained via radiochemistry is counted on a liquid scintillation counter. In order to accurately measure the ’ 4C and 3H response of the liquid scintillation counter, the background response of the liquid scintillation counter must be determined. For each batch of samples, a background sample is counted to determine the background count rate for the sample. This background count rate is subtracted from the gross count rate for each sample to determine the net
or 3 H count rate for each sample in the batch. This net count rate is then used to determine the activity concentration in the sample.
For a sample without the presence of 14C or 3H, the gross count rate for the sample will be statistically equivalent to the background. If the background count rate is greater than the gross sample count rate, the activity concentration will be negative. This is statistically equivalent.

6.0 DATA QUALITY
Data verification and data validation were performed to ensure the data were of the proper quantity and quality to support the objectives of the final status survey.
6.1 Data Verification
Data verification ensures that the requirements stated in the survey design (i.e., SAP, Quality Assurance Program Plan (QAPP), and standard operating procedures (SOP) were implemented as prescribed. The number, type, and location of measurements performed were compared to the survey design in the SAP (Bartlett, 2008a). Additional measurements were performed to satisfy the requirements of the survey design as necessary. All of the measurements required by the SAP (Bartlett, 2008a) were performed using the methodologies and SOP specified.
Instruments used to perform radiological measurements were calibrated within the last twelve months as described in the QAPP (Bartlett, 2008b) and the appropriate SOP. Instrument response and background were checked before and after every shift to ensure instruments were operating properly. All radiological instruments were working within acceptable parameters as specified in the QAPP (Bartlett, 2008b) throughout the survey.
6.1.1 Scan Surveys
The scan surveys of horizontal surfaces required in the SAP (Bartlett, 2008a) were performed using the floor monitor and hand held gas proportional detectors. Scan surveys of building surfaces in the wood frame structure and greenhouse were completed as required. No conditions were identified that would interfere with the ability to collect adequate data during scanning surveys.
6.1.2 Static Measurements
A minimum of ten static measurements were performed in each area as required in the SAP (Bartlett, 2008a). In addition, there were additional judgmental measurements performed based on the results of the scan surveys with hand held instruments. The only conditions that were identified that could interfere with the ability to collect adequate data were associated with access issues. The hand held gas proportional detectors were too large to fit inside small diameter pipes such as drains and sink traps, so no static measurements could be performed in these areas. Whenever practical the drain lines and sink traps were removed and included in the waste shipment of materials from the detached wooden shed at the Hybridoma Center.
6.1.3 Wet Smears
A minimum of ten wet smears were collected in each survey area as required by the SAP (Bartlett, 2008a). The wet smears were generally collected at the same location where a static measurement was performed. The exception was areas such as inside drains which were inaccessible for static measurements because of the size of the hand held detectors. No conditions were identified that would interfere with the ability to collect adequate data during scanning surveys.
6.2 Data Validation
Data validation ensures that the results of data collection activities support the objectives of the survey as documented in the QAPP (Bartlett, 2008b). The results of the radiological final status survey of Gill Tract were reviewed and evaluated against the survey objectives. Because all
BARTLETT NUCLEAR, INC & CABRERA SERVICES, INC. Page 32
Gill Tract Final Status Survey Report
measurements were below the survey method MDC values and did not indicate the presence of any residual radioactivity above background levels, graphical plots were not developed. The data are adequate to support the objectives of the final status survey.
6.2.1 Floor Monitor
The calibration of the floor monitor was performed by an approved vendor prior to collecting data at the site. Efficiency calibrations were performed using 14C, technetium-99, and strontium-90 to provide a range of efficiencies for beta particles with different energies. Carbon-14 has beta particles with the lowest energy, 156 keY, so the 14C efficiency was used to perform all of the detection sensitivity calculations and to convert measurement into activity. A copy of the calibration certificate for the hand held gas proportional counters are referenced in Attachment C, Instrument Checks and Calibration Forms.
The efficiency and sensitivity calculations show that the hand held gas proportional detectors are acceptable for demonstrating compliance with the acceptance criterion for small areas of elevated ’4C activity using scanning measurements, but static measurements of at least one minute are required to demonstrate compliance with the acceptance criterion for average 14 C activity.
6.2.2 Hand Held Gas Proportional Detectors
The calibration of the hand held gas proportional detectors was performed by an approved vendor prior to collecting data at the site. Efficiency calibrations were performed using ’4C, technetium-99, and strontium-90 to provide a range of efficiencies for beta particles with different energies. Carbon-14 has beta particles with the lowest energy, 156 keV, so the 14C efficiency was used to perform all of the detection sensitivity calculations and to convert hand held measurement into activity. A copy of the calibration certificate for the hand held gas proportional counters are referenced in Attachment C, Instrument Checks and Calibration Forms.
The efficiency and sensitivity calculations show that the hand held gas proportional detectors are acceptable for demonstrating compliance with the acceptance criterion for small areas of elevated ’4C activity using scanning measurements, but static measurements of at least one minute are required to demonstrate compliance with the acceptance criterion for average It
activity.
6.2.3 Laboratory Measurement
Laboratory blanks, laboratory duplicates, and laboratory control samples were analyzed with each batch of samples. A total of 11 sets of laboratory QC measurements were performed with the 146 wet smears, or one set of QC measurements for every 13 samples. A total of 4 sets of laboratory QC measurements were performed for the 29 soil samples, or one set of QC measurements for every 7 samples. The QAPP (Bartlett, 2008b) required one set of QC measurements for every 20 samples, so the number of QC measurements was adequate to evaluate the laboratory measurement performance.
The 84 laboratory blank results and the 84 duplicate analyses were all less than the detection limit for the gross beta liquid scintillation measurements. The standard deviation for the 84 LCS results was less than 2% of the mean value. Therefore, all of the laboratory QC analyses complied with the requirements of the QAPP (Bartlett, 2008b). The results of the laboratory measurements are adequate to support the objectives of the final status survey.
BARTLETT NUCLEAR, INC & CABRERA SERVICES, INC. Page 33
Gill Tract Final Status Survey Report
During reviews of the raw liquid scintillation data a problem was identified with the luminescence values. The luminescence values are usually less than 10 for liquid scintillation counts, but values as high as 90 were identified for the wet smear counts. The source was identified as chemiluminescence, where a chemical reaction with the scintillation cocktail results in counts that are incorrectly assigned as radioactivity. The laboratory was consulted and the window of beta particle energies was adjusted to exclude counts resulting from chemiluminescence. The change in the window settings resulted in lowering the tritium efficiency from 0.41 to 0.265.
The ability of the liquid scintillation cocktail to transmit the scintillations of light affects the counting efficiency and is measured by placing a radioactive source next to each sample and performing a measurement. The ability to transmit light is recorded as the tSIE value. Values for the tSTE lower than 300 indicate a potential for a reduction in the counting efficiency. Because the gross beta liquid scintillation counts were not associated with a specific radionuclide, the effect of the tSIE on efficiency could not be quantified. The impact on the results is a potential for the MDC to be higher than reported in samples with a tSTE lower than 300 because of uncertainty in the efficiency value. Liquid scintillation results for samples with a tSIE value less than 300 received a J-flag because of the increased uncertainty associated with the reported result. A total of 12 out of the 146 wet smears (8%) reported tSIE values less than 300. The source of the low tSIE values is apparently the larger quantities of dirt or dust from surfaces.

7.0 CONCLUSIONS
The activity levels associated with the wood frame structure and greenhouse at the Hybridoma Center on the Gill Tract site are below the Regulatory Guide 1.86 levels. Based on the results of the radiological surveys at Gill Tract and the associated reference areas, there is no dose above background at the Hybridoma Center or the planting field. The surveys of the laboratory hood exhaust ducts, roofs, and ground floor sump did not identify any radioactivity above the acceptance criterion. There is no indication that the outside surfaces at Gill Tract were impacted by the use of radionuclides at the Hybridoma Center. The levels of radionuclides in surface soil in the planting area and the radionuclide concentrations in the area surrounding the Hybridoma Center are consistent with the reference area concentrations and would not contribute any additional dose to members of the public.
Based on the results of the final status surveys performed at Gill tract the entire 10 acre property is eligible for release from radiological controls with no restrictions.

Supplemental Sampling and Analysis Plan: Radiological Final Status Survey - Gill Tract
1. Introduction
This plan has been developed as an addendum to the approved Sampling and Analysis Plan (SAP) for the final radiological survey of the Gill Tract site (Reference 1). All data quality objects (DQOs), acceptance criteria, survey design requirements, quality assurance and quality control aspects detailed in the approved plan (Reference 1) remain in effect during the implementation of this supplemental soil sampling plan.
The scope of this plan is limited (i) to the collection and analysis of soil samples collected from the planting field at the Gill Tract site and from selected reference areas and (ii) to the evaluation of the associated analytical data.
2. Sampling Data Quality Objectives
The objective of this plan is to determine whether the concentrations of carbon-14 (C-14) and tritium (H-3) in the soil of the Gill Tract planting field are below the acceptance criteria in the approved Gill Tract SAP (Reference 1).
Statement of the Problem
Does residual University research related radioactivity, if present in the survey unit (Gill Tract Planting Field), exceed the release criteria?
The potential that the C-14 and H-3 concentrations in the soil of the Gill Tract planting field exceed the acceptance criteria exists. Accordingly, the null hypothesis for this sampling effort is that the C-14 and H-3 concentrations in the soil of the planting field exceed the acceptance criteria. The data from the soil samples collected under this plan will be of sufficient quantity and quality so as to support either the acceptance or rejection of the null hypothesis.
Identification of the Decision/Alternative Action
The principal study question was derived from the approved SAP (Reference 1) and modified as follows: Do the C-14 and H-3 concentrations in the surface soil of the Gill Tract planting field exceed the acceptance criteria?
The final decision regarding the radiological status of the Gill Tract planting field will rely on the analytical data from the soil samples collected during the implementation of this plan.
Alternative actions for failure of the C- 14 and H-3 concentrations to meet the acceptance criteria have been limited to performing a site-specific dose assessment.
Inputs to the Decision
Based on an assessment of the historic use of radioactive material at the Gill tract site (Reference 2), C-14 and H-3 are the only radionuclides-of-concern.
Volumetric samples are the only type of measurements to be collected under this plan and soil is the only medium to be sampled.
The acceptance criteria in this plan are limits on C-14 and H-3 concentrations in soil as stated in the approved SAP (Reference 1): _<O.5 pCi per gram of soil for C-14 and :54.O pCi per gram of soil for H-3.

Supplemental Sampling and Analysis Plan: Radiological Final Status Survey� Gill Tract
Define the Boundaries of the Survey
All soil samples from the Gill Tract planting field will be collected within the boundaries shown in Figure 1.
All reference soil samples from the reference areas will be collected within the boundaries shown in Figures 2 through 5. The reference areas are as follows:
� Reference Area 1 (REF-0t) is a South Berkeley garden, located on the north side of Heinz Avenue. The reference area is approximately 2 miles south of the Gill Tract planting field. Figure 2 provides the sampling map for this area and the GPS coordinates and sampling point identifications. Attachment 1 provides the driving instructions from the Gill Tract site to Reference Area 1.
� Reference Area 2 (REF-02) is the University Gardens West, located a short distance in the southwest of the Gill Tract planting field. Figure 3 provides the sampling map for this area and the GPS coordinates and sampling point identifications. Attachment 2 provides the driving instructions from the Gill Tract site to Reference Area 2.
� Reference Area 3 (REF-03) is the Junior High School Garden at the MLK School East, located approximately 1 mile southeast of the Gill Tract planting field. Figure 4 provides the sampling map for this area and the GPS coordinates and sampling point identifications. Attachment 3 provides the driving instructions from the Gill Tract site to Reference Area 3.
� Reference Area 4 (REF-04) is the El Cerrito Hillside Nature Area, located approximately 2.5 miles north of the Gill Tract planting field. Figure 5 provides the sampling map for this area and the GPS coordinates and sampling point identifications. Attachment 4 provides the driving instructions from the Gill Tract site to Reference Area 4.
Constraints on Data Collection
Soil in the planting field has been plowed to a depth of approximately 6 inches and harvested annually. Therefore any potential contamination in the planting field would be homogeneously distributed throughout the top six inches of soil. Accessibility is not an issue for the Gill Tract planting field as long as samples are collected at times when research activities are not being performed. Soil sample collection will be scheduled and conducted to cause the least amount of interference with research activities in the planting area as possible.
Accessibility to the randomly selected sampling locations may be an issue for some of the references areas. However, additional (contingency) sample locations have been randomly selected for each reference area and are identified on Figures 2 through 5. Sampling locations deemed inadequate or inaccessible by the Sampling Team members will be replaced by a sample collected at the next available contingency location.
Quality Assurance
All applicable quality assurance requirements described in the approved SAP (Reference 1) remain in effect during the implementation of this sampling plan. As an added quality assurance measure, at least 15% of the soil samples from the Gill Tract planting field and the reference areas will be identified as split samples to be analyzed for C-14 and H-3 by three independent laboratories.
Supplemental Sampling and Analysis Plan: Radiological Final Status Survey - Gill Tract
Decision Rules
The criteria for accepting or rejecting the null hypothesis are as follows:
1. If the concentrations of C-14 and H-3 in all samples are below the acceptance criteria and the sum of the ratios of concentration to acceptance criteria is less than 1.0 for each sample location, then the null hypothesis will be rejected. The C-14 and H-3 concentrations in Gill Tract planting field meet the acceptance criteria and the land can be released for unrestricted use.
2. If the average concentrations of C-14 and H-3 in the planting field soil are below the acceptance criteria (and the average sum of the ratios of concentrations to acceptance criteria is less than 1.0) but the concentrations of C-14 and/or H-3 exceed the acceptance criteria at some sample locations (or the sum of the ratios of concentration to acceptance criteria exceed 1.0 at some sample locations), then acceptance or rejection of the null hypothesis will depend on the outcome of the Wilcoxon Rank Sum (WRS) test.
3. If the average concentrations of C-14 and/or H-3 in the planting field soil (or the average sum of the ratios of concentrations to acceptance criteria exceeds 1.0), then the null hypothesis will be accepted. The C- 14 and/or H-3 concentrations in Gill Tract planting field exceed the acceptance criteria and the land can not be released for unrestricted use without further evaluation (e.g., site-specific dose assessment).
Tolerable Limits on Decision Errors
The total number of random soil samples, 40 (20 from the Gill Tract planting field and 20 from the references areas), assumes a Type I decision error rate (a) and a Type II decision error rate (13) of 0.05 and includes the recommended 20% additional samples to ensure statistical power.
Analytical uncertainty is controlled by the analytical laboratory through the use of appropriate instruments, methods, techniques, and QC. Minimum detectable concentrations (MDCs) for C-14 and H-3 using specific analytical methods have been established. The required sensitivity for the analysis of the soil samples are: :50.5 pCi/g for C-14 and :54.0 pCi/g for H-3.
Optimize Design
The WRS Test will be applied to the soil sample data. The data from the reference areas identified above will be used in the WRS Test.
3. Instructions
General Sampling Instructions
Prior to conducting sampling, create a field work package that includes a copy of this plan, and copies of Procedure OP-005, Volumetric and Material Sampling, Procedure OP-018, Decontamination of Equipment and Tools, Procedure OP-008, Chain of Custody, and applicable procedure forms.
Use Figure 1 to locate the random sampling points in the Gill Tract planting field. Figure 1 provides a visual reference and the GPS coordinates and label for each sample location. Use Figures 2 through 5 to locate the random sampling points in the reference areas. A GPS unit (with the sample location coordinates as input) should be used to locate each sample point in the Gill tract planting field and in each of the reference areas.

Supplemental Sampling and Analysis Plan: Radiological Final Status Survey - Gill Tract
Figure 6 provides an aerial view of the neighboring areas of the Gill Tract site, including the planting field and the Hybridoma Center. A total of 10 biased soil samples will be collected from locations at or near the Gill Tract site. The number of samples and targeted areas are:
1. Two samples from the immediate soil area previously sampled on the west side of the Hybridoma Center,
2. Four samples from the soil areas located south of the Hybridoma Center (i.e., 2 samples from the parcel of land on the north side of Monroe Street and 2 samples from the University Park area, including a sample from the baseball diamond (refer to Figure 6),
3. One sample from the soil area located east of the Hybridoma Center (between the Hybridoma Center and San Pablo Avenue),
4. One sample from the soil area located at the northerly section of the Gill Tract site at Buchanan Street, and
5. Two samples from the soil area on the west and east sides of Middle School (i.e., 1 sample from the ball field on the west side of the school and 1 sample from the yard on the east side of the school). Middle School is located on the west side of Jackson Street opposite the Gill Tract planting field (refer to Figure 6).
Because these samples are to be collected on a biased basis, the specific sampling locations will be identified and recorded at the time of the sampling.
All soil samples shall be collected in accordance with Procedure OP-005, Volumetric and Material Sampling (provided in Appendix A to this plan). If necessary, use a 3/8-inch screen to remove gravel, stones, and gross organic debris. Repair the hole created during sampling before leaving the location.
Cleaning of sampling tools shall be performed in accordance with Procedure OP-018, Decontamination of Equipment and Tools (provided in Appendix A to this plan).
Control of all soil samples shall be maintained in accordance with Procedure OP-008, Chain of Custody (provided in Appendix A to this plan).
Retain a copy of all paperwork (procedure forms, field notes, logbook, etc.) as project records.
Sampling should be performed during clement weather and daylight hours.
The labeling convention for collected soil samples from the Gill Tract planting field shall follow the labeling convention shown on Figure 1. Similarly, the labeling convention for collected soil samples from the reference areas shall follow the labeling convention shown on Figures 2 through 5.
Specific Sam pliny Instructions
Coolers (for shipment) and sample containers have been provided by each of the contracted laboratories. Keep these supplies separated by the laboratory that provided them (i.e., do not co-mingle the sample containers) to ensure that the same cooler and the appropriate sample containers are returned to the correct laboratory. During sampling, ensure that:
� The sample containers supplied by the Areva Laboratory are used only for those soil samples to be sent to the Areva Laboratory.
� The sample containers supplied by GEL Laboratories are used only for those soil
5
Supplemental Sampling and Analysis Plan: Radiological Final Status Survey - Gill Tract
samples to be sent to the GEL Laboratories. The sample containers supplied by Eberline Services are used only for those soil samples to be sent to Eberline Services.
Once filled and labeled, secure the lid of the sample container with tape and enclose the container in a zip-lock plastic bag for shipment. Verify that each plastic bag is securely closed.
All soil samples shall be maintained in a cool environment through use of a cooler and cold packs. Cold packs shall also be placed in the cooler to keep the samples cool during the sample collection period and also when samples are transported to the laboratories.
A Chain of Custody (CoC) form shall accompany the samples to the laboratory. Ensure that the required sensitivity for C-14 and H-3 analysis (i.e., 50.5 pCi/g for C-14 and :54.0 pCi/g for H-3) and instructions to maintain the samples in a cool environment upon arrival at the laboratory are recorded on the CoC form.
� Use the Areva NP Environmental Laboratory Sample Submission Form (included in Attachment 5) as the CoC form for all samples sent the Areva Laboratory.
� Use the GEL Chain of Custody and Analytical Request (included in Attachment 5) as the CoC form for all samples sent the GEL Laboratory.
� Use Form OP-008-01, Chain of Custody/Analysis Record (included in Attachment 5) from procedure OOP-008 as the CoC form for samples sent to Eberline Services.
Gill Tract planting field QA split samples:
The soil samples from the Gill Tract planting field are to be labeled OOL-01-001-F through OOL-01-020-F, as indicated in Figure 1. The split samples will be collected at locations 10, 13, and 18 (based on random number generation), and will be identified by Si and S2 at the end of the sample identification code. For example, the 2 split samples from location 10 will be labeled as OOL-01-010-S1 and OOL-01-010-S2.
For each location designated as a split sample location, collect approximately 500g of soil, remove stones and gross organic debris, and thoroughly mix the soil in a single container prior to filling the sample containers provided by the laboratories. After filling the sampling 3 sample containers, return the excess soil to the hole created by sampling.
Biased samples:
The soil samples from the biased locations are to be labeled OOL-05-001-B through OOL-05-010-B. The specific location of each sample will be recorded (e.g., on a copy of Figure 6, the sample forms, in a logbook, or as a GPS measurement).
Reference Area sampling and OA split samples:
Sampling maps (Figures 2 through 5) have been developed for 4 identified reference areas. Each Figure provides several contingency sample locations.
The soil samples from each Reference Areas are to be labeled REF-OX-00 1-B through REF-OX-005-13, where "X" indicates the Reference Area number: 1, 2, 3, or 4 (refer to Figures 2 through 5).
QA split samples will be collected at locations REF-01-001-B, REF-01-003-B, and REF-04-004- B (based on random number generation), and will be identified by Si and S2 at the end of the
rc
Supplemental Sampling and Analysis Plan: Radiological Final Status Survey - Gill Tract
sample identification code. For example, the split samples from sample location REF-01-001-B will be labeled as REF-.01-001-B-S1 and REF-01-001-B-S2.
For each location designated as a split sample location, collect approximately 500g of soil, remove stones and gross organic debris, and thoroughly mix the soil in a single container prior to filling the sample containers provided by the laboratories. After filling the sampling 3 sample containers, return the excess soil to the hole created by sampling.
If an identified (i.e., labeled) sampling location at a given reference area is inaccessible, collect a sample at the first available contingency location. Record the reason of inaccessibility and the identity of the contingency location that is used as the replacement location on the sampling form or in a logbook.
If a reference area is inaccessible or unavailable, collect samples at the unused contingency locations in any of the other reference areas. Record the reason of inaccessibility or unavailability of the reference area and the identity of the contingency locations that were used as alternate on the sampling form or in a logbook.
If a sample location is unavailable and a sample is collected from a contingency location, use the labeling convention as shown in Figures 2 through 5 for the contingency locations.
