ABSTRACT:
A method 20 for decontaminating specially selected plastic materials comprised of polymers and copolymers of unsaturated organic acids and other specially selected plastic materials, which have become radioactively contaminated, includes dissolving such plastic materials in an aqueous solvent 34 and treating the resulting solution selectively via filtration 36, ion-exchange absorption 40, and precipitation 44 processes to remove particulate and dissolved radioactive contaminants. The treated aqueous stream may be discharged to a sewage stream and the separated plastic materials can be disposed of in a sanitary landfill or recycled into other plastic products.
