Method of treating waste material containing radioactive cesium isotopes

Patent ·
OSTI ID:5115929

A method is described for treating waste materials containing radioactive cesium isotopes. The process involves mixing an aqueous solution of an alkali metal silicate (sodium is the most desireable alkali metal), a hardening agent (Portland cement is readily available), and a plurality of shale particles with the waste materials. Once the mass has solidified, it may then be exposed to the leaching action of an aqueous environment. Results have shown that the leachability of cesium from a solidified mass is greatly reduced when shale is present in the solidified material. 14 claims.
