The radioactive wastes (RW) of the near-surface storage facility of the Chepetsky Mechanical Plant SC (Glazov, Udmurt Republic, Russia) uranium refinery, which was operated from 1951 to 1980, were studied. It was determined the first 2–3 m of waste mainly consist of rock-forming minerals: SiO2, various aluminosilicates, feldspars, and zeolites. Wastes occurring after 3 m of depth are represented by calcium compounds: carbonate, sulfate, fluoride. The content of uranium in the RW varies in a wide range from 0.001 to 0.5 wt%. The specific activity of most wastes is determined by 226Ra and raised with increasing depth from 0.05 to 70 kBq kg−1.
