NORMS are Class 7 TDG Regulated

Which means you must be trained to ship or handles these materials


The key in DANGEROUS GOODS• Once classified by the

shipper as a dangerous good and NORMS must be measure to be a dangerous good by the reading on radiation meter YOU NOW HAVE A CLASS 7 CHEMICAL AS DEFINED UNDER THE LEGISLATION!


Key Objectives

• Understand the Transportation of Dangerous Goods requirements for Class 7 Radioactive Packages.

• Identify the requirements for packaging radioactive material for Class 7 shipment.

• Identify the documentation required for Class 7 shipments.

• State the differences between ground and air requirements for Class 7 packages.

• Understand the classification, different package limits and shipping requirements for radioactive packages.


Norms and Class 7

In Canada and the USA TDG/HAZMAT Class Seven regulated Naturally Occurring Radioactive Material (NORM) is material found in the environment that contains radioactive elements of natural origin, ( which means you must have TDG training for your staff and when hauled to site. But are you exempt from law from having a RSO on site?


Once classified that’s where the law changes to must be trained

• All minerals and raw materials contain radionuclides of natural origin. The most important for the purposes of radiation protection are the radionuclides in the U-238 and Th-232 decay series.

• For most human activities involving minerals and raw materials, the levels of exposure to these radionuclides are not significantly greater than normal background levels and are not of concern for radiation protection. However, certain work activities can give rise to significantly enhanced exposures that may need to be controlled by regulation. Material giving rise to these enhanced exposures has become known as naturally occurring radioactive material (NORM).

Understand the basic requirements of the regulations governing the transport of radioactive material.

Regulatory Requirements

Transport is Governed by:

Safety Series on the Regulations for the Safe Transport of Radioactive Material (International Atomic Energy Agency)

Packaging and Transport of Nuclear Substances Regulations(Canadian Nuclear Safety Commission)

TDG Transportation of Dangerous Goods Regulations (Clear Language)(Transport Canada)


Training required for people who offer for transport or transport dangerous goods

Training provides information necessary to enable employee to do the job

There are nine classes of Dangerous Goods

Class 1 – ExplosivesClass 2 – GasesClass 3 – Flammable LiquidsClass 4 – Flammable SolidsClass 5 – Oxidizing SubstancesClass 6 – Poisonous/ InfectiousClass 7 – RadioactiveClass 8 – CorrosiveClass 9 – Miscellaneous

Package Type


Radioactive Material is Class 7

There are no packing groups or risk groups for this classification.

Package Type


Class 7 is always a primary class

Primary Class labels on packages take precedence over all other classes

…except 2, 2.3, 2.4, 2.1, 5.2, 6.2

…but labels for these and Class 7 must be used together as all are considered primary classes

Generally, radioactive packages would not need any other label as the other primary classes are rarely present in radioactive

packages.

Package Type


The first question to ask, when shipping radioactive material is...

“Do I need to follow the regulations?”

There are few exceptions and virtually all radioactive material used in a hospital setting would fall under the Class 7 Transport of Dangerous Goods Regulations.

Package Type


You do not need to follow the regulations if you are shipping radioactive material......

Over private roads with controlled access [none shipped at the hospital]

As substance in a human or animal (<10-6A2/kg) [injected patients and animals exempt]

Substance contained in consumer product [none shipped at the hospital]

As Natural ore (<10xA2) [none shipped at the hospital]

Within private property [between buildings at VG exempt .... NOT between sites]

Exempt amounts (generally < 70 Bq/g) or less than 10 MBq (270µCi) of 99mTc!

[thus virtually every radioactive shipment must follow the TDG regulations]

Substance in animal tissue or remains (<10-6A2/kg) [any organ or tissue samples exempt]

Package Type

Do I need to follow the regulations?

The next thing to check is to see if your package is exempt by activity

levels.

CDHA MS Clip Art File

Package Type

If your activity is less than TDG or CNSC stated limits then you do not have to follow Class 7 Regulations

Virtually nothing is less so all hospital shipments must follow TDG Class 7 Regulations.

Package Type


If it is not exempt....then is it a radioactive package so determine if it should be....

Excepted or Type A?To determine the package type you have to....

Check item activity limits

Differentiate between Liquid or solid

Categorize as Instrument or materialKnow the A2 values

Determine if Surface Dose Rate <5 µSv/hr

Package Type


Example: Activity Limit is 10-4 the A2 Value for liquid. If activity is over this then it has to go as Type A package.

Activity Limit for

Excepted Packages

is:

(from IAEA SS TS-R-1)

Use different activity limits

if you are shipping

instruments

(from IAEA SS TS-R-1)

Use different activity limits for solids versus liquids

Mixtures of Nuclides in same package

Sum of Nuclide Activities/A1 and 2 values should be < 1

Hospital shipments rarely require this calculation

Package Type


The Empty Package

If the package previously contained radioactivity you can have

β and residual activity up to 100 x 4Bq/cm2 over 300cm2 [120kBq or

3.2uCi]

You can ship empty without labels but you still need shipping document,

UN identification 2908 and the wording

‘Radioactive Material, Excepted Package, Empty Packaging’

Package Type


The Empty Package

If nothing is in the package and you document that any β / contamination is below the limits

(4Bq/cm2 over 300cm2)

then it can go as a regular non TDG package.

Package Type


The Shipping Container

The Shipping Container must follow strict design requirements

AND

Departments must have a copy of the shipping container certificate of testing

Packaging


Key Point 1Need certificate for shipping container

The certificate verifies the container has met the International Atomic Energy Agency standard to ensure the container can

withstand normal transport conditions.

Examples of the testing includes water spray, free drop, stacking and penetration.

It is the responsibility of the manufacturer of the container to ensure the testing is completed.

Packaging Summary


Vehicle Placards(placed on all four sides of the vehicle)

Only required for Yellow III package shipments but it is the responsibility of the shipper (sender/consignor) to provide four of

them to the transport carrier each time.

Some carriers have a supply so may not request them. You should have a supply just in case if shipping Yellow III packages.

Packaging


Special Labels

Packages may require additional labels if they belong to another

dangerous goods category such as blood products (biohazard) or are

liquids and require a specific package orientation.

Packaging


Contamination Limits

4 Bq/cm2 for and 0.4 Bq/cm2 for

Averaged over 300 cm2
