    Gamma Spectrum Analysis of IAEA International Intercomparison Samples

    • In 2006, the international intercomparision of gamma-radionuclides was conducted by ultra-low background HPGe γ-spectrometer systems in our lab. According to IAEA’s rules, activities of 54Mn, 60Co, 65Zn, 134Cs, 137Cs, 241Am, 109Cd, and 210Pb in soil and water, and 40K, 137Cs in grass have to be measured. The activies of these radionuclides were performed by Genie 2000 for γ-spectra analysis and by LabSOCS for efficiency calibration. Our laboratory obtained excellent scores with 89% for acceptable and 0 for not acceptable. The percentage of acceptable is obviously higher than average value 64% in all the participant labs, while those of not acceptable are lower than average 29%.
