[Comparative evaluation of biological availability of 137Cs in soil of various types of forest ecosystems].
On five forests plots varying in species composition of woody plants and soil properties, 137Cs vertical distribution and 137Cs forms occurring in different horizons of forest soils have been studied. It was found that bulk 137Cs and contents of physico-chemical forms of this radionuclide in different horizons of forest soils vary considerably within both plots with different characteristics and individual horizons. The reported regularities can explain observed differences in 137Cs distribution in forest ecosystems of various types.
