The thermosetting plastic on the base of shale phenols, namely, althiein, is suggested for radioactive waste solidification. The ecological safety of spent ion exchange resins localization in althein determined according to radionuclide washing from the solidified products and the strength of these products under different storage conditions, is evaluated. The radionuclide release into environment from fixed blocks does not exceed 0.05-0.15% in respect to the initial radioactivity
