• To overcome the impediment against practical utilization of the technically already available process of solidifying low- and intermediate-level radioactive wastes for disposal in ocean bottom, arising from the regulatory minimum density of 1.2 prescribed for such solidified wastes, a method is proposed of thickening the polyethylene with 3638 w/0 sodium sulfate anhydride to raise the density above 1.2. The resulting thickened polyethy-lene loaded with simulated radioactive waste showed a monoaxial compressive strength far exceeding 150 kg/cm<SUP>2</SUP>, and proved to possess good stability in deionized water in immersion tests lasting 400 days. Polyethylene was also found to provide a volume reduction factor far higher than obtained with cement or asphalt solidification.
