Patent ID: 6936745

Claim:
A method of partially or completely encapsulating radioactive particles comprising: exposing radioactive particles or material, alone or in combination with other materials, to a precursor monomer solution that is capable of polymerizing in situ due to the inherent radiation of the radioactive material, whereby the radioactive material is partially or totally encapsulated in the resultant polymer wherein the precursor monomer solution comprises one or more monomers selected from the group consisting of water-soluble, ethylenically-unsaturated acids and acid derivatives; and a crosslinking agent; and wherein the crosslinking agent is selected from the group consisting of methylenebisacrylamide, ethylenebisacrylamide, any water-soluble N,N′-alkylidene-bis(ethylenically unsaturated amide), 1,3,5-Triacryloylhexahydro- 1,3,5-triazine, and combinations comprising at least one of the foregoing crosslinking agents.
