- Аннотация: The results of retrospective assessment of the density of radionuclide deposition as result of theChernobyl accident for pine plantations growing on a northern highway of the Belarusian sector of the 30-kilometer zone around the station are presented. A decrease in the total density of soil contamination and theproportion of radionuclides of the fuel component of emissions was found with growing distance from theChernobyl NPP. A change in the contribution to the absorbed dose rate from external β- and γ-radiationalong the height of woody plants depending on the time and location of experimental objects in relation tothe Chernobyl NPP is analyzed. The important role of external β-radiation in the formation of irradiation ofcrowns of woody plants in first months after radioactive fallout is shown. The decrease in the absorbed doserate from external β- and γ-radiation in the studied plantings is proportional to the contribution of short-livedradionuclides to the total radioactive contamination. Up to 40% of the radiation dose absorbed by crowns ofwoody plants was accumulated in the first month after radioactive emissions, and up to 60% was accumulatedduring the next two months. The results of a retrospective assessment of the formation of the radiation situ-ation in the first year after emergency fallout in pine plantings can be used to assess the long-term conse-quences of irradiation for living organisms.
