Abstract. From the sanitary and hygienic point of view it is necessary to study not only the chemical composition of soils (macro- and microelements), but also the content of natural and anthropogenic radionuclides regardless of the anthropogenic load on the territory. Active development of nuclear industry since the middle of XX century, nuclear tests all over the world and as a consequence of global increase of radiation background still requires deep radiationgeochemical studies of various landscapes. Radiation-geochemical studies of not only anthropogenic, but also natural radionuclides have an important scientific and applied significance. Specific effective activity of natural (40K, 226Ra, 232Th) and anthropogenic (137Cs, 90Sr) radionuclides in the profile of dark gray forest soils of the Uporovsky district of the Tyumen region. In the work the zones of accumulation and dispersion of natural and anthropogenic radionuclides in the profile of the studied soils of agrocenoses and conditionally background soils of dark gray forest soils are identified and analyzed, and the character of their interaction with macro- and microelements is outlined.
