FIELD: cleaning after emergency on nuclear power plants. SUBSTANCE: method involves distribution of material which is solved in water and precipitates with iodine and its compositions. This material is distributed in air as powder or melt drops which size is about 5 mcm or as water solution in aerosol particles which size is not greater than 60 mcm. When material is distributed in air, it is affected with ultrasound. Since distributed material is solved in water, contaminated vapor is condensed on distributed particles, which size provides effective treatment of all volume of distributed material. EFFECT: increased safety.
