Role of fuel particles in contamination of cereal production with 90Sr in Ivankiv district of Kyiv region

Abstract

In the year 2011 sampling of soil and grain in Ivankiv district of Kyiv region at all fields adjacent to the ChNPP exclusion zone was carried out, where the cereal crops were planted. In all samples 137Сs and 90Sr activities were measured. Besides, in the soil samples the exchangeable fractions of 90Sr and calcium and acidity of the soil solu-tion were determined. Dependence of 90Sr soil-grain transfer factors was specified.
