FIELD: treatment of radioactive wastes; recovery of radionuclide-contaminated air cleaners in radiation- hazard industries. SUBSTANCE: fibrous layers disposed within water-repelling filter element are acted upon by aerosol of binder based on solution of epoxy-containing hydrocarbon and hardener. Fibrous layers treated in this way are hardened, stacked in briquettes, subjected to heat compression, and transformed to environmentally friendly solid phase. Binder material solution is first dispersed in air flow. EFFECT: enhanced degree of waste decontamination. 5 cl, 1 tbl, 4 ex
