These results will make it possible to carry out the final stages of research and to justify the possibility of restoration of certain types of forestry activities in radioactively contaminated territories. The results obtained in the third stage of work: - the specific activity of 137Cs in the samples was measured; - average values of density of radioactive soil contamination are calculated; - the methodology for soil sampling was developed to establish current levels of soil contamination; - the coefficients of transition and accumulation of radionuclides in the aboveground phytomass of the herbaceous and mossy cover of the studied types of forest plant conditions were calculated; - dependences were established between the density of radioactive soil contamination and the specific activity values of 137Cs in the samples to substantiate the possibility of using the studied components by the local population; - the sanitary condition of pine plantations in forests, where forestry activities were stopped, taking into account the productivity and technical suitability of timber, was evaluated.
