Abstract: Studies of the radionuclides behavior in the soils of Red Forest landfill in the nearest 5-km ChNPP zone were carried out during 2014 - 2015. The parameters of vertical migration and halftimes of upper 5-cm soil layer decontamination were obtained. Forms of occurrence of 90Sr and 137Cs, as well as the disperse composition of the Chernobyl origin fuel particles were evaluated. Behavior of radionuclides described in conditions of the convection-diffusion model and the parameters of the model slightly changed over the past decade.

Keywords: contamination, vertical migration, radionuclides, speciation of radionuclides, dispersed distribution of the fuel particles.
