FIELD: power industry.
SUBSTANCE: chemical decontamination method of radioactive materials involves surface treatment of materials with water solution of chemical reagents. As water solution of chemical reagents there used is the solution containing sodium hydroxide, potassium hydroxide, calcium hypophosphite, pine rosin and water as its base and having the following component ratio (wt %): sodium hydroxide - 4.14-4.16, potassium hydroxide - 1.15-1.17, calcium hypophosphite - 0.16- 0.18, pine rosin- 0.87-0.89, water - up to 100.
EFFECT: invention allows developing easier, more effective and environmentally friendly method of chemical decontamination of radioactive contaminated materials using environmentally friendly composition of chemical reagents.
