摘要：

Depth profiles of the long-lived radionuclides, Cs-137, Sr-90, Pu isotopes and Am-241 were examined in undisturbed sandy, peaty and Podsol soils in the Chernobyl 30 km exclusion zone sampled around 10 years after the accident. Two Podsol soils, which have different radioactive deposition characteristics, have also been examined. Activity ratios of Pu-239,Pu-240/Cs-137, Sr-90/Cs-137, and Am-241/Cs-137 in the 0-1 cm layer of the two Podsol soils differed very much. Speciation of the radionuclides by sequential selective extraction was examined in the soils. Depth profiles of the soils have been analyzed according to the speciation results and soil characteristics.
