Identify the Law Detection Limit (L.D.L)
written records of relevant procedures and results
and documentation
verification of the appropriate calibration and
conditions of operation of dosimetry and monitoring
equipment
QA &QC
Every two months (before reading the field cards) we read the Q.C and blank cards by the reader .
Before reading any card we measured the PMT noise and the Reference Light
Charts for PMT noise
Charts for Reference Light

Future Plan
Improvement of the Quality Assurance and Quality Control
* Involved in Internal & external comparison.
* Starting internal & external audit for our Labs.
