Description
Summary: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.
