AbstractAbstract
[en] This report contains the results of the intercomparison IAEA-321 on the determination of radionuclides in milk powder. Initially participants were requested to determine the levels of 134Cs, 137Cs, 40K, 90Sr and invited to provide data for other radionuclides. The participants included 61 laboratories located in 29 countries, and statistical evaluation of their data yield recommended values for these four radionuclides. Additional radionuclides reported were 226Ra and 232Th, however insufficient data exists to statistically determine recommended values for these radionuclides. The recommended values for radionuclide determination are: 134Cs: 15.5 Bq/kg; 137Cs: 72.6 Bq/Kg; 40K: 552 Bq/kg; 90Sr: 3.3 Bq/kg. Tabs
