摘要：

Trends in Cs-137 distribution over the parts of coniferous (Pinus sylvestris L.) and deciduous (Betula pendula Rocht.) trees are described. The trees have been selected in the stationary experimental plots located in southwestern Bryansk Oblast, Russian Federation. The distribution of Cs-137 in the wood along the trunk height is shown to be nonuniform. The effects of Cs-137 content in the xylem sap on the accumulation of this radionuclide in the leaves and needles are assessed. The factors controlling, Cs-137 accumulation in the components of woody plants are revealed, and their significance is estimated.
