A method 20 for decontaminating plastic products and materials which have become radioactively contaminated. The treatment method 20 involves dissolving such plastics in a dissolution tank 28 in an organic solvent and treating the resulting solution by a solvent extraction technique in column 36 to remove particulate and dissolved radioactive contaminants from the plastic. The contaminants can be buried in a low level radioactive waste site and the separated plastic material can be disposed of in a sanitary landfill or recycled into other plastic products.

A method of removing low level radioactive contaminants from plastic materials contaminated in a radioactively contaminated environment in order to concentrate the radioactive contaminants for more compact disposal in a low level radioactive waste disposal facility and in order to be able to recycle

A method of removing low level radioactive contaminants from plastic materials contaminated in a radioactively contaminated environment in order to concentrate the radioactive contaminants for more compact disposal in a low level radioactive waste disposal facility and in order to be able to recycle the plastic materials or dispose of the plastic materials in a conventional manner without restrictions associated with radioactivity contaminated plastic materials, comprising the steps of: dissolving the plastic materials in an organic solvent to produce a feed stream; contacting the feed stream in a solvent extraction device with an aqueous solvent to cause the contaminants to transfer from an organic phase to an aqueous phase.
