Дезактивация радиоактивных отходов, образующихся при ликвидации последствий радиационных аварий

Abstract

In this work we compare effectiveness of use of natural aluminosilicates, sorbents based on them and synthetic sorbents for deactivation of radioactive waste generated after liquidation of consequences of radiation accidents. The PF-hydrated titanium dioxide showed cesium distribution coefficient higher than 2.0 • 103 ml / g in deactivation solutions after reagent purification of soil (solution 1M ammonium acetate). In case of deactivation solutions containing EDTA, synthetic sorbents T-35, NPF-hydrated titanium dioxide and natural aluminosilicates (clinoptilolite and glauconite) were effective at the same degree.
