 The main goal of the work is the development of means and methods for assessing the results of the redistribution of subsurface contamination due to wind uplift of radioactive aerosols in the Chornobyl Exclusion Zone, taking into account the spatial heterogeneity of the territory and the location of the main anthropogenic sources of radioactive aerosol, nature use under normal and extreme meteorological conditions. During the execution of the work, in particular, a complex of mathematical models was built to assess and forecast the level of radioactive contamination of the atmosphere, the redistribution of radionuclides in the components of the environment due to natural processes and man-made influences in the Chornobyl Exclusion Zone and beyond. Based on data from satellite measurements of radiation power, a method for estimating the intensity of radionuclide emission into the atmosphere during forest fires in radioactively contaminated territories is proposed. Methodological recommendations have been developed for determining the beta activity of "hot" particles and their distribution by activity based on autoradiography of contaminated surfaces. Contamination by radioactive aerosols of the surface layer of the atmosphere of the near zone of the Chornobyl NPP after the construction of the New Safe Confinement was investigated. The results of the work have been implemented in the Nature Reserve "Drevlyanskyi" of the Ministry of Environmental Protection and Natural Resources of Ukraine, which allows quickly assessing radiation conditions on the territory of nature protection departments and determining the expediency and scope of necessary measures for radiological protection of the environment, workers and the population.
