This standard defines a framework to be used to create a national or an organizational National Institute of Standards and Technology (NIST)-traceable measurement quality assurance (MQA) program that optimizes the quality of radioassays performed by service laboratories. This standard serves as a guide for MQA programs developed for specialized sectors of the radioassay laboratory community, i.e., bioassay, routine environmental monitoring, environmental restoration and waste management, radiopharmaceuticals, nuclear power radiochemistry, and other areas involved in radioassays
