§ Congressional findings and purposes; SUBCHAPTER I—REMEDIAL ACTION PROGRAM (§§ – ) SUBCHAPTER II—STUDY AND DESIGNATION OF TWO MILL TAILING SITES IN NEW MEXICO (§§ – ). Many of the findings related to occupational exposures and adverse health outcomes presented in this chapter are based on studies of uranium and hard-rock miners (e.g., worker-based radon studies) for periods of disease risk when the magnitude of the exposures was much greater than the exposures reported at most mines and processing facilities in North America today.

a uranium mine/mill complex in the United States occurred near Church Rock, New Mexico, in June A breach of an earthen dam containing solid and liquid tailings caused the release of 1, tons of radioactive mill waste and 95 million gallons of mine effluents. Uranium Mill Tailings and Associated Wastes Mill tailings and associated wastes present radiological and nonradiological hazards. Among the radioactive elements found in tailings are forms of uranium, thorium, and radium. Other nonradiological but potentially toxic ingredients include lead, arsenic, cadmium, chloride, fluoride, and various.

Radon is a noble gas that escapes easily into the atmosphere from unstabilized mill tailings, whereas radium, its parent, is a potential pollutant of surface groundwaters. Due to the long half-life of thorium, the parent of radium, the quantity of radon and radium in the tailings will diminish by only one-half in roug years.

The federal Bureau of Mines investigated the absorption of radium and thorium from waste uranium leach liquor by clays and other materials. This work was conducted in support of the Bureau's goal of minimizing the environmental conflicts, impacts, and occupational hazards associated with mining and mineral processing operations.

Uranium mining is the process of extraction of uranium ore from the ground. The worldwide production of uranium in amounted to 60, tonnes. Kazakhstan, Canada, and Australia are the top three producers and together account for 70% of world uranium production.

Other important uranium producing countries in excess of 1, tons per year are Niger, Russia. This is a fantastic and comprehensive overview of the systematic minerology of uranium and thorium minerals, including an overview of all the major ore deposits around the world.

It is splendidly illustrated with pictures of almost every described species, /5(10). Backgrounder on Uranium Mill Tailings Printable Version.
