scope:

This technical report describes test methods of instruments that count and measure the energy of photons emitted by RADIONUCLIDES in vivo and in vitro without the option of imaging. This includes, for example, well counters and organ probes. Geiger-Mueller counters and dose calibrators are not within the scope of this document. As part of QUALITY CONTROL this document is defining ROUTINE TESTS to be performed by the user of gamma radiation counting systems to maintain proper operation conditions. The results of these ROUTINE TESTS are compared to the REFERENCE DATA determined during or after ACCEPTANCE TEST.
