US Patent:

7662738, Feb 16, 2010

Filed:

May 22, 2006

Appl. No.:

11/419579

Inventors:

Mark P. S. Krekeler - Centreville VA, US
Stephen C. Elmore - Stafford VA, US

Assignee:

George Mason Intellectual Properties, Inc. - Fairfax VA

International Classification:

B01J 29/06

US Classification:

502 63, 588 9

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, which in turn 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 may be collected, heated and analyzed.

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.

International Classification:

A61N 5/00
A61K 51/00

US Classification:

424 111, 600 1

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.
