Calculation of the acceptable radionuclide level in irrigation water during irrigation by the method of rain

Abstract

According to the results of many years radioecological studies, the analysis was performed of the formation of radioecological environment on the territory of irrigated agriculture ecosystems where irrigation is carried out by water from the basins of the Dnieper and Southern Bug rivers. Influence of the purging and filtration waters of technological reservoirs with high content of 137Cs and 3H on the formation of radioecological situation in reservoirs of irrigated agriculture ecosystems is shown. According to the results of a full-scale experiment on the study of the transition of radionuclides to agricultural crops under irrigation and on the results of field studies on the agricultural lands of this irrigation ecosystems in the south of Ukraine, the permitted levels of 134Cs, 137Cs, 89Sr, 90Sr, 106Ru, 54Mn, 58Co, 110mAg, 65Zn, 3Н in irrigation water were determined. The results of studies can supplement the environmental criteria of the quality of irrigation water standards of the content of radioactive substances.
