Abstract: Investigation of the distribution of 137Cs and 90Sr in pine plantations in different edaphic conditions. Confirms that the stock of radionuclides in the forest litter depends on the range of the contamination and varies from 10 to 70% for 137Cs and 20 to 60% for 90Sr. With increasing moisture in soil, in each gradation of trophic network, increases R 137Cs in wood and reduces 90Sr. The stock of 137Cs and 90Sr in the wood of pine plantations in various edaphotopes depends on state of plantation and the levels of accumulation of radionuclides.

Keywords: forest radioecology, 90sr, vegetation, soil
Abstract:The algorithm of display of 90Sr’s behavior mechanism in forest ecosystems by method of imitating modeling is developed. Distinctive features of algorithm: the 90Sr contents in vegetation is subdivided into two parts (outside and internal pollution), whose dynamics is considered separately; dynamics of radionuclide is considered in connection with dynamics of organic substance; it is supposed, that 90Sr’s behavior in plants is similar to Ca behavior; the biological availability 90Sr contained in a soil, is integrated function of time and physico-chemical properties of the given soil. On the basis of offered algorithm the model is constructed which is used for realization of a number of numerical experiments, including reconstruction of a situation of pollution of forest ecosystem on grey forest soils in result of Kyshtym accident. The quantitative estimations of intensity of 90Sr redistribution between stand components and soil are received. The modern problems of creation of prognostication models of 90Sr dynamics in the forest ecosystems are discussed.

Keywords: density of contamination of soil, ecotop, trophotop
Abstract:The studies of 137Cs and 90Sr accumulation characteristics by birch wood (Betula pendula Roth.) growing in different edaphic conditions. Describes the increase in soil fertility from trophotops A to D results in 5-fold 137Cs transfer factor decrease and 2-fold decrease of 90Sr. Soil humidity increase for each grade of trophic net results in the increase of 137Cs transfer factors to wood and decrease for 90Sr. Total activity of 137Cs and 90Sr in birch wood plantation depends on productivity of plantation and on radionuclide transfer factors depending on different plantation conditions. In the most prevailing edaphotops (B2, ВЗ, С2 and C3) birch wood accumulates 0.6-1.2% of 137Cs and 13-19% of 90Sr from total activity of radionuclides in biogeocenosis.

Abstract: Chernobyl accident has influenced greatly all spheres of life of the affected territories, changing the life-style of the local population. [1, 2]. Investigation of the radionuclides behavior in natural conditions becomes more and more important which is connected with the fact that radionuclides are drawn into substances rotation and are actively accumulated by the plants and animals, that means that they become integral link of the food chains and are of a great importance in the functioning of the ecosystems. Deposition of radionuclides in the forest system is often higher than in agricultural arrears. Specific ecological features of the forests often lead to the high degree of accumulation of contaminating radionuclides. Organic matter high content in the forest soil and its stability increase the transfer of radionuclides from soil into plans which lead to high content of radionuclides in lichens, mosses, mushrooms and berries. Radionuclides transfer to game in such conditions could bring to the situation when some people actively consuming game meet will be highly exposured
