There were designed methods and materials for effective deactivation directed on the removal of radiation and chemical pollution and minimization of secondary radioactive waste (including minimization of liquid radioactive waste):
- by formation of colloidal solutions of solid particles with their further fixation in the form of a special foam, “dry foam” or gel;
- by transferring pollutions into the water-soluble state, fixation in the form of stable complexes, followed by adsorption of porous material or pumping out with the use of special pump nozzles;
- by transferring pollutions into volatile compounds absorbed by special materials with the use of special technical substances (for pollution cleaning stuck in cracks and pores).
All proposed methods are based on the use of commercially available raw materials and materials.
Substances are intended to deactivate pollution from surfaces which are located horizontally, vertically, under the slope, ceilings, equipment of various geometric shapes. Surfaces can be metal, wooden, glass, concrete, covered with ceramic tile, plaster, oil paint, etc. These surfaces may have cracks and splits (including asphalt surfaces), to be moist or oily with varying degrees of radiation and / or chemical pollution.
