Abstract:
Objective To analyze the specific activity of radionuclides based on laboratory intercomparison.Methods Intercomparison of the measurements of radioanuclides 232Th,40K and 137Cs in soil samples,organized by National Institute for Radiological Protection,China CDC,was conducted using HPGe γ-spectrometry and the method of relative comparison and efficiency curve,respectively.Results The relative deviations were all less than 5％compared to the reference values in the conditions of both relative comparison method and efficiency curve method used,respectively.The relative deviations to the reference values were less than 4％for the relative comparison method.Conclusions Both the relative comparison method and the efficiency curve method can be used to measure the activity of radionuclides in the intercomparison samples,and the latter is superior to the former.
