Abstract
Regardless of the time after the Chernobyl disaster, the problem of radioactive contamination is very urgent. At present, 6.7 million hectares of our country remain contaminated, of which 1.2 million hectares of land are contaminated with 137Cs with a density of 42 to 589 kBq/m2 (1–15 Ci/km2). There are 2,161 settlements in the radioactively contaminated territories, where there are about 3 million inhabitants. For the inhabitants of rural areas of these settlements, the main part of food products belongs to the products obtained from the land, so the definition of plant contamination by artificial radionuclides 137Cs and 90Sr on the lands affected by radioactive contamination. The Chernobyl accident is relevant, since the internal dose of radiation is formed due to consumed products, grown in private plots. Reducing the transition of radionuclides 137Cs and 90Sr from soil to crop production is one of the main tasks of agricultural production on contaminated radionuclide lands. The realization of these researchers will clarify the current state of migration of data of radionuclides in the soil-vegetation link in the agro eco systems of the Central Forest-steppe of Ukraine. From the moment of the Chernobyl accident, leading scientists conducted a sufficiently large number of scientific studies on the migration of 137Cs and 90Sr in agricultural production facilities, their accumulation in food products and the assessment of human exposure doses. The focus of the scholars focused on the territory of Polissya. Preferably migration of 137Cs and 90Sr in separate links and systems of the trophic chain. In addition, somewhat more attention is paid to 137Cs, which is the main dose-forming radionuclide. In addition, in forest-steppe areas that are radioactively contaminated, a significant proportion of pollution occurs at 90Sr, whose migration rate, according to scientists, will gradually increase. All these data led to the need for a detailed study of the state of migration of 137Cs and 90Sr in the soil-vegetation chain of agro eco systems of agricultural enterprises and private parts of the central forest-steppe affected by radioactive contamination because of the Chornobyl accident in the remote period. The purpose of these studies was to study the migration of 137Cs and 90Sr in the chain of soil plants in the villages Yosypivka and Tarasivka of the Kyiv region of the central forest-steppe of Ukraine, as well as the determination of the coefficients of transition of 137Cs and 90Sr from typical black soil to vegetable products for the next prognostication. The investigated areas of the Bila Tserkva district are located in the north-eastern part of the right-bank forest-steppe region of Ukraine and are represented mainly by typical low-humus black soil in the forests within the boundary plains. In order to achieve this goal, selection of samples of crop production and soil was carried out on private plots of peasants of Yosypivska and Tarasivska...Keywords
