FIELD: radioactive pollution prevention. SUBSTANCE: method involves mixing waste with clay using water-hardening ratio of 1.5-3.0, keeping suspension for at least ten minutes and mixing it with binder using weight ratio of clay and binder in range of (15-50):(50-85) and water-hardening ratio of 0.5- 1.6. Clay may be kaolin, bentonite or spondylite. Binder may be hydrate lime, clinker Portland cement or thin-ground clinker with additional 2.5-5 % of clinker or Portland cement. EFFECT: low leaching rate, increased mechanical strength. 2 tbl
