M, Registration Date 20-02-2001 Organization Radioecological Center of Ukrainian Nathional Academy of Sciences popup.description2 Research objects: the following reclamation drainage systems: Prypiatska, Chystogalovska, Khabne.The aim: Ground and work out system of measures to renew of regulation capacity of land reclamation systems for improvement quality of surface flow with the Exclusion Zone. Methods: the natural research,experiments, laboratory studies . Degree underflooding of reclamation systems was analyzed. The chemes of formation of hydrochemical and radionuclides composition in surface waters under conditions of retaining, run-off control and pass without retaining were determined. A range of laboratory experiments, directed on radionuclides' leaching charactiristics assesment, described. Patterns of solid phases for the experiments had been collected from the right of Pripiat' river in the different subdivisions of micro landscapes. Duration oof the laboratory experiments was comparable with periods of seasonal floodplains sinking. The share of leaching Cs-137 and Sr-90 significantly depends on soils moistuning regim e, hydrodinamic conditions and specifics of landscapes.
