Essay

Work is devoted to consideration of technogeneous radionuclides geochemistry in the affected zone of Chernobyl NPP. It is established that isotopic composition of U in soils of near zone of Chernobyl NPP is shifted toward enriching by U-234 and U-235 isotopes relatively to a natural constant because of accumulation of dispersed reactor fuel, U-236 was found in the same soils. An amount of reactor U fuel contaminated soils of near zone of Chernobyl NPP is commensurable with amount of the natural U contained in them. It is experimentally shown that U-236 and Pu-239, 240 are inadequately distributed in the system "soil - solution", Pu demonstrates higher sorption ability, than that of U.
