Abstract: A method of removing radioactivity from the interior of a building by transporting radioactive material within a slurry comprising water and metal salt hydrate, precipitating out or otherwise filtering out the then contaminated material outside the building, thus removing it in a continuous fluid recirculation system, and storing the precipitated out material while providing shielding of radiation, thereby to provide radiation protection without requiring conventional large mass to block the radioactivity. A toxic waste storage facility includes a building having a portion located below ground level, walls for bounding an interior space in the building, and recirculating fluid for removing thermal energy from the building and for providing radioactive shielding and absorption at least at part of the roof of the building.

Abstract: A method of coating a substrate, for example, to abate asbestos or lead paint by encasement, includes dispersing particulate solids in at least one liquid thermosetting resin, about 100% of said solids having a U.S. Standard mesh size of about 225 mesh or smaller and at least about 10% of said solids having a U.S. Standard mesh size of about 325 mesh or smaller; dispersing an effective amount of at least one catalyst in said resin to cure said resin within a determined period of time, the resulting mixture being a curable resin system; and spraying said curable resin system on to said substrate using an airless spray system. A product made by such method and an article comprised of such a coating.

Abstract: A foamed polymeric material is coated with a fire protective thermal barrier product. The polymeric material, thus protected, is used for on-site application on walls, ceilings, decks and roofs of buildings. The thermal barrier product (hereafter "thermal barrier" for brevity) is also used to protect foam plastics in fire-resistant factory-made building panels, the exteriors of tanks and other vessels, and the coverings over pipes. The thermal barrier comprises a normally fluent thermosetting synthetic resinous material in which is dispersed an effective amount of hydrated magnesium sulfate and, optionally, inert inorganic fillers, pigments and the like.
