Abstract

A method for concentrating and/or entrapping radioisotopes from an aqueous solution, said method comprises mixing the aqueous solutions with at least one inorganic salt under conditions in which said salt forms at least one stable hydrate, incorporating the tritium as water of crystallisation. Said hydrate will neither react nor degrade for extended periods of time, and accordingly a method of stabilising large amount of radioactive waste is provided.
