- Scope
- This standard specifies the routine method for analyzing low specific activity gamma radionuclides in solid state, liquid state or homogeneous samples that can be converted into these two states by using semiconductor gamma ray spectrometer with high energy resolution capability. This standard is applicable to the analysis of samples whose activity is greater than the detection limit LD of the spectrometer [Appendix A (Supplement)], and the Y characteristic lines of each nuclide can be distinguished. Therefore, the samples are generally only subjected to simple physical treatments such as drying, pulverizing, and stirring, instead of chemical separation. When the sample must be chemically separated, parameters such as the recovery rate should be determined according to the corresponding procedures.
