ABSTRACT:
A method is provided for treating waste materials containing radioactive cesium isotopes which comprises mixing an aqueous solution of an alkali metal silicate, a silicate hardening agent and a plurality of shale particles with such waste material and then solidifying the mixture to form a solidified mass which when subjected to an aqueous environment is characterized by the relatively low leachability of cesium isotopes therefrom.
