  • Conventional Uranium Mills NRC.gov

    This is because the mill tailings contain the heavy metal ore constituents, as well as a residual amount of radium, which is produced during the radioactive decay of uranium. The radium, in turn, decays to produce a radioactive gas, known as radon, which may then be released to the environment. Because this radon is a radioactive gas, which may be inhaled and deposited in the respiratory tract, some

    2016-2-22  Due to the long half-lives of the radioactive constituents involved, safety of the deposit has to be guaranteed for very long periods of time. After rainfall, erosion gullies can form; floods can destroy the whole deposit; plants and burrowing animals can penetrate into the deposit and thus disperse the material, enhance the radon emanation and make the deposit more susceptible to climatic erosion.
