Features of removal of 137Сs by grain and leguminous crops in conditions of Zhitomir Polissia

Abstract

The purpose. To find out features and character of removal of radioactive nuclides by grain and leguminous crops in Zhitomir Polissia for formation of economically effective and ecologically balanced systems of agrarian production in the region. Methods. Sampling and preparation of samples for measurements was carried out with the help of standard procedures. Results. Variability of correlation between potential ability of agricultural plants to accumulate radioactive nuclides and intensity of torrents of removal of radioactive nuclides with crops is revealed. Efficient fertilizer systems are selected for decrease of accumulation of radioactive nuclides by grain and leguminous crops. Conclusions. Radioecological situation in the low-purity agroecosystems of Ukrainian Polissia owing to termination of counter-measures varies extremely slowly and is completely determined by physical disintegration of radioactive nuclides 137Cs and raise of motility of 90Sr in the system «soil — plant». Therefore it is necessary to possess the full information on properties of soils and density of contamination with the purpose of optimum utilization of resources at conducting counter-measures that, in its turn, demands scientific accompaniment.
