Title: COMPOSITION FOR DUST SUPPRESSION AND CONTAINMENT OF RADIOACTIVE PRODUCTS OF COMBUSTION
Abstract:
The invention relates to means for protecting the environment from the consequences of fires complicated by a radiation factor. A composition for dust suppression and containment of radioactive products of combustion after a fire with a radiation factor has been extinguished comprises, as a surface-active substance, a mixture of an anionic, a non-ionic and an amphoteric surface-active substance, and has the following ratio of components: 3.0-7.0 % by weight of an aqueous solution of polyvinyl alcohol (in terms of a mass fraction of dry product); 0.1-0.3 % by weight of plasticizer; 11.0-29.0 % by weight of surface-active substance; with water making up the remainder. The invention makes it possible to carry out dust suppression and containment of radioactive products of combustion which are formed on surfaces, including at elevated temperatures, after a fire has been extinguished.
