FIELD: radiation protection. SUBSTANCE: composition containing vanadium pentoxide and mixture of sodium, potassium, and sulfur-containing salts is applied on surface of polluted material. Amount of vanadium pentoxide constitutes 25 to 75% of total weight of composition, K/Na atomic ratio ranges from 0.3384 to 1.8144, and sulfur content in salt mixture is 29.33-33.84 wt %. Covered surface is heated for 10-30 min mainly at 850-950 C, after which resulting scale is removed from the surface. Operation, if necessary, is repeated. EFFECT: increased purification efficiency. 3 cl, 1 tbl
