The Cs-137 intake in agricultural crops from soils differing in the degreeof soil development

摘要

The accumulation of Cs-137 in agricultural crops grown on old arable and newly developed leached chernozems and dark-gray forest soils has been studied. Significant differences were found between the accumulation of radionuclides in crops depending on the soil properties, degree of soil development, and biological features of plants. The Cs-137 intake in cereal crops from the newly developed leached chernozems was 5.8-7.2 times higher than from the old arable soils. Maximum accumulation of Cs-137 was in grain legumes and legumes, minimum in cereals.
