The study of distribution of radioactive pollution of the "Chernobyl trace" the combination of geophysical, geochemical and landscape techniques allows to obtain a comprehensive assessment of the lateral redistribution of Cs-137 in the landscape. A typical catenary of the selected pairing within the landscapes of Predpolesie, Predopolie and Opolie. Based on the data of airgamma survey and field radiation monitoring on the landscape basis are revealed the radionuclide levels of Cs-137 contamination. Landscapes of Opolie are characterized by low contamination. The conducted research allowed to reveal the more intense the lateral migration of 137Cs for both slopes of the southern and South-Western exposure. The role of forest vegetation as a biogeochemical barrier: under the influence of forest vegetation accumulation of radionuclides reaches 30-40%.
