| Abstract: | Many kinds of environmental samples including total diet samples, were collected in the Chernobyl (Ukraine) vicinity and in Ibaraki prefecture (Japan). Six radionuclides and twelve stable elements were analyzed. After samples were dry-ashed, radioactivities of137Cs,134Cs,40K,60Co and54Mn were determined by  -ray spectroscopy with a germanium detector. Strontium-90 was determined by low-background  -spectrometry. Stable elements were determined by inductively coupled plasma atomic emission spectrometry (ICP-AES). Comparison of the levels of radionuclides between the Ukraine and Ibaraki showed the former were several times to a few tens of thousands of times higher than the latter, depending on the samples. |
