Abstract: The distribution of 137Cs and 90Sr in oak, pine and hornbeam stands at different levels of groundwater is analyzed. It is proven that the scale of migration of 137Cs and 90Sr in the vertical profile of the soils is determined by level of ground water in the experimental field: closer to the surface the ground water is found, the less radionuclides is contained on the surface of the soil, and vice versa. Coefficients are determined by “fast” and “slow” quasidiffusion of 137Cs and 90Sr. Description of the contribution of these components to the overall migration of radionuclide transport in the vertical profile of the soil. Coefficients of decreasing of 137Cs and increasing of 90Sr, for the element of overground phytomass by the decreasing of groundwater, is observed.
