| Abstract: | This paper describes the intercomparison results on radioactivity measurements of radioactive nuclides in ALMERA SOIL 1 (soil) and ALMERA SED 1 (lake sediment) environmental samples. The intercomparison was organized by International Atomic Energy Agency (IAEA). The measurements of activities were completed with a HPGe low background anticompton Gamma spectrometer using the methods of relative comparison and efficiency curve. Nine nuclides in ALMERA SOIL 1 and six nuclides in ALMERA SED 1 were measured respectively. The measured values of the activity concentration agreed with the overall mean within the range of experimental uncertainties except for the activity of 60 Co in ALMERA SOIL 1 sample. It also discusses the reasons why some nuclides were not detected and few measured values were divergent. ( |
