Abstract

Sapropels, hydrolyzed lignin (HL), clay-salt slimes (CSS) and phosphogypsum (PG) have been used as components to develop efficacious and ecologically safe amendments. Methods and models for forecasting effectiveness of countermeasures based on application of such amendments have been proposed. It has been found that 137Cs selective sorption on organo-mineral amendments is enhanced after incubation, as compared with the calculated values on the basis of the fractions of total mass of source components and their own ability for 137Cs selective sorption. The measured RIP(K) value for the mixtures of soddy-gley soil and organo-mineral amendment at 2% was 1.2–1.6 higher than the calculated one, and at 10% 1.5–1.7 times higher than the calculated.
