FIELD: polymeric compositions based on aqueous solution of polyvinyl alcohol used for normalizing radiation situation.
SUBSTANCE: proposed composition used for normalizing radiation situation has aqueous solution of polyvinyl alcohol and water-soluble salt. Salts of calcium and/or magnesium, and/or barium, and/or cadmium, and/or zinc, and/or nickel (II), and/or lead (II), and/or manganese (II), and/or sodium and/or ammonium rhodanides are used as water-soluble salts, proportion of ingredients being as follows, mass percent: polyvinyl alcohol, 8.0 - 13.0; water-soluble salts, 1.0- 25.0; water, the rest. Such composition is characterized in long life (up to 1.5 years) and makes it possible to solve problems of decontaminating, isolating, and keeping surfaces away from radioactive contaminants.
EFFECT: extended service life and enlarged functional capabilities of proposed composition.
