Objects of researches are soils, plant-grower products. A research purpose is to identify the factors and their influence on the intensity of radionuclides migration in order to block them in the soil. Determine the transfer factors of radionuclides from soil to plants, their dependence on the quality of the soil. Research methods and equipment is caesium-137 in soil determined by spectrometry method on the analyzer of impulses АІ-1024-95 with the stintillation detector БДЕГ- 2-23; in plants - on the betta-radiometer РУБ-014ПС. Measuring of gamma-background was conducted by а dosimeter РМ1701М. Strontium-90 defined by radio-chemistry method on the device УМФ-2000 and spectrometer "Gamma-plus". Agrochemical researches were spent according to the techniques actual in agroservice. Data of radiological inspection of soils near the 9 settlements on the area of 69.5 thousand hectares was generalized. The density of soils pollution by radiocaesium more than 1 Ci/km2 has been found on 80% of the surveyed areas. Agriculture lands has examined on the area of 3.2 thousand hectares. Weighted average value of pollution is 1.4 Ci/km2. Average level of green mass pollution is 158 Bq/kg and it limits 27-846 Bq/kg. Above the permissible level have been polluted 13% from analyzed products. Pollution of soil by strontium-90 above 0,15 Ci/km2 is revealed on 40% of the surveyed areas, weighted average value of pollution is 0,15 Ci/km2. Pollution of green mass by strontium-90 is in limits 2-199 Bq/kg, having average value of 46 Bq/kg. Potash fertilizers and liming of soils is influenced on the intensity of radionuclides transit from soil to plants (reduces the level of radionuclide accumulation in plants in 1,3-2,8 times). Milk with excess of the permissible level of pollution has been found in 25 locations. It was found that cow's pasture is held on nofarmland, in forests, swamps, where factors of the radionuclide transfer are too high. Assessment of countermeasures effectiveness is implemented. Agrochemicals (liming of soils and mineral fertilizers) provide а reduction of radionuclides in plant produce, together with it increases economic efficiency of crop production. Effect of liming and on crop yields, and on the accumulation of radionuclides with time gradually decreases. For increase the radiation and the economic efficiency of countermeasures necessary to introduce mineral and organic fertilizers and liming of acid soils. Correlation analysis was carried out with results of researches. Informing about received results has been done.
