Makhon'ko, V. Medvedev] The mechanism of vertical migration of radionuclides along the soil profile is studied. For large averaging, the process can be described by the sum of the rates of effective diffusion and vertical advection of a radionuclide. The results of theoretical calculations of the137Cs concentration profiles in light and heavy soils for actually observed atmospheric fallout in 1954-1999 are compared with the experimental profiles in mountain frozen-taiga and mountain frozen-forest tundra soils of southern Transbaikal. The rate of vertical migration is estimated and the reasons for the high137Cs contamination density of soil in this region are discussed. 4 figures, 27 references.
