The Northern-Crimean Canal as a model object for radioecological study of the Chernobyl radionuclides transport to the Black Sea

“…2) were by 1.7 -3.4 times lower than those in the water before irrigation on the model polygons 1 and 2 (stations 4 and 5) (Fig. 2) Sr concentration in the NCC water demonstrates that its decrease to the pre-accidental level will continue up to 2030 [13]. By that time the amount of 90 Sr in the NCC water will decrease by 3.8 times in comparison with the time of existence of 97% of its atoms.…”

“…By that time the amount of 90 Sr in the NCC water will decrease by 3.8 times in comparison with the time of existence of 97% of its atoms. Total activity of strontium in water used for agricultural irrigation in the Crimea was about 5900 GBq [12,13]. At that time 90 Sr concentration in the NCC water did not achieve maximum permissible concentration for drinking water accepted in Ukraine in 1991 -1997.…”

“…Оно определялось хроническим вторичным поступлением 90 Sr с водами Днепра через сбросные ответвления СКК (Мирзоева, 2013;Gulin et al, 2013;Mirzoyeva et al, 2013) Известно (Понизовский, 1965), что хло-риды щелочных металлов и другие соли резко повышают растворимость стронциевых солей.…”
