    en.wikipedia.org/wiki/Andreev_Bay_nuclear_accident

    The repository, constructed in the early 1960s, is a naval base on the shore of the Zapadnaya Litsa bay. It consists of two piers, a stationary mooring bay, a sanitation facility, spent fuel pools in building #5 (unused since 1989), three 1,000 m 3 (35,000 cu ft) dry storage containers, a 40,000-tonne crane, an open-air field for storing spent nuclear fuel containers, a security checkpoint ...

    en.wikipedia.org/wiki/Industrial_radiography

    Gamma radiation sources, [2] most commonly iridium-192 and cobalt-60, are used to inspect a variety of materials. The vast majority of radiography concerns the testing and grading of welds on piping, pressure vessels, high-capacity storage containers, pipelines, and some structural welds.

    en.wikipedia.org/wiki/Radiation_Portal_Monitor

    First generation RPMs often rely on PVT scintillators for gamma counting. They provide limited information on energy of detected photons, and as a result, they were criticized for their inability to distinguish gamma rays originating from nuclear sources from gamma rays originating from a large variety of benign cargo types that naturally emit radioactivity, including cat litter, granite ...

    en.wikipedia.org/wiki/Ducrete

    DUCRETE (Depleted Uranium Concrete) is a high density concrete alternative investigated for use in construction of casks for storage of radioactive waste. It is a composite material containing depleted uranium dioxide aggregate instead of conventional gravel, with a Portland cement binder.

  6. Radioactive waste - Wikipedia

    en.wikipedia.org/wiki/Radioactive_waste

    The back-end of the nuclear fuel cycle, mostly spent fuel rods, contains fission products that emit beta and gamma radiation, and actinides that emit alpha particles, such as uranium-234 (half-life 245 thousand years), neptunium-237 (2.144 million years), plutonium-238 (87.7 years) and americium-241 (432 years), and even sometimes some neutron ...
