FIELD: chemical technology for rare- earth elements. SUBSTANCE: method used for decontaminating water- soluble salt wastes to reduce amount of non-radioactive ballast in wastes to be disposed involves melt dissolving in water and chemical settling of radioactive components on barium sulfate sediment. Prior to dissolving, metal chlorides are thermally volatilized from salt waste melt by atomizing and/or stirring the melt at temperatures of 480-550 C. EFFECT: reduced volume of radioactive wastes to be disposed. 2 cl, 1 tbl, 6 ex
