Migration behavior of released radionuclides in the river system in the exclusion zone of the Chernobyl nuclear power plant
[en]This work has been carried out for assessment of secondary migration of the Chernobyl-derived radionuclides through a river system in terms of their amount and forms of the mobile component. It would contribute: a) to clarify controlling factors which cause remobilization/immobilization of the released radionuclides for the river system in the vicinity of the Chernobyl Nuclear Power Plant; and also, b) to find effective countermeasures to prevent secondary contamination in a river system after a nuclear accident. With the objectives described above, migration behavior of the radionuclides in the river system in the exclusion zone was investigated for suspended solid, bottom sediment and river water. In this paper: i) the result of radiochemical analyses for dissolved radionuclides; and, ii) physical form of 137Cs in river waters are described and discussed
