Abstract
The paper presents the results of a radiation survey of sod-podzolic and gray forest soils of reference agricultural plots of the Vladimir region. The study established background values of specific activities of the studied radionuclides in the soils of reference sites. According to the density of contamination of the arable horizon of gray forest and sod-podzolic soils 137Cs and 90Sr, it was determined that all reference areas of the region belong to uncontaminated territories. The power of the exposure dose of gamma radiation of soils and the contribution of radionuclides of gamma emitters to the formation of the gamma background of soils are determined. Using correlation analysis, the influence of individual physical and chemical properties of soils on the behavior and distribution of radionuclides in soils and the relationship between the content of radionuclides was determined. Based on the values of the specific activity of 137Cs and 90Sr in plant products grown on the soils of reference sites, rows of crops were constructed according to the decreasing ability to accumulate radionuclides from the soil. All grown plant products for all types of crops fully met the veterinary requirements for the content of 137Cs and 90Sr in plant feeds (hay, green mass and feed grain). According to the transition coefficients, it was found that the process of transition of 90Sr from both types of soils to plants proceeded more intensively than the transition of 137Cs. The calculated coefficients of linear correlation between the values of the specific activity of 137Cs and 90Sr in soils and plants revealed the strength of the relationships and the nature of the dependencies.
