Abstract:
The present invention relates to synthetic nanoparticle soil materials that comprises about 0.5% to about 20% metal powder by mass, and about 0.5% to about 30% mineral powder by mass, mixed together with quartz-rich sand and a polymorph mineral of aluminum silicate, creating a sand mixture that may be mixed with a silicic acid solution. The ratio of quartz-rich sand to the polymorph mineral of aluminum silicate is between 1:99 and 99:1. The polymorph mineral of aluminum silicate can be kyanite, andalusite, sillimanite, mullite or any variant or substitute of these minerals. The silicic acid solution can be made by mixing silicic acid powder to water in a ratio being 1:99 to 99:1. The ratio of sand mixture to silicic acid solution can be between 1:99 to 99:1.

Abstract:
A radioactive containment composition may be created for containing radionuclides from a radioactive material by mixing a clay mineral with water. This mixture may form an aqueous clay suspension. The mixture can be refined by filtering to remove coarse material. The aqueous clay suspension may be applied to a radioactive material, allowing the radionuclides to be exchanged with cations in the aqueous clay suspension. The resulting aqueous slurry, a silver-based solution may be added to produce a suspension. The suspension may be collected, heated and analyzed.

Abstract:
A radioactive material sequestration system may include a radionuclide containment composition dispenser and a sorption based media container. The radionuclide containment composition dispenser may be configured for holding a radionuclide containment composition and be capable of dispensing the radionuclide containment composition to remove radionuclides from a radioactive material. The radionuclide containment composition is a mixture of a clay mineral and water. The sorption based media container may be configured for holding a sorption based media; receiving dispensed radionuclide containment composition; and sequestering the radionuclides. The radioactive material sequestration system may also include a probe.

US Classification:
588254
Abstract:
The compound is a clay aqueous suspension made of at least one 2:1 layer phyllosilicate clay mineral, at least one 1:1 layer phyllosilicate clay mineral, and water that can be used to sequester asbestos, such as chrysotile, as well as dust and other fibrous particles, at all scales of contamination.
