[en] In this paper a vertical transfer of radionuclides in soils of different genesis after Chernobyl NPP accident was studied. Analysis of obtained data revealed that the main content of cesium-137 is located in 0-5 cm layer of turf-podsolic, sandy-loam and loamy soil provided the lack of their humidification, and of light un-bogged (automorphous) soil as well. Cesium-137 penetration into light un-bogged soils with that sings of surplus humidification is approximately 10 cm deep. Strontium-90 as global birth so Chernobyl origin migrates more rapidly than cesium-137 because of less strong bond with soil absorbing complex. Cesium-137 migration coefficients amounted (0.03-0.46)·10-7 cm2/s for a slow component, and for the fast one (0.39-0.67)·10-7 cm2/s. Strontium-90 migration coefficients in the experimented sites, amounted (0.07-0.58)·10-7 cm2/s for a slow component, and for the fast one (0.64-1.28)·10-7 cm2/s. (authors)
