The ~(137)Cs intake in agricultural crops from soils differing in the degree of soil development

摘要

The accumulation of ~(137)Cs 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 ~(137)Cs 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 ~(137)Cs was in grain legumes and legumes, minimum in cereals.
