Other statutes provide the EPA with authority to establish standards for specific wastes or facilities. These include the Nuclear Waste Policy Act, Waste Isolation Pilot Plant Land Withdrawal Act and the Energy Policy Act of 1992, that affect development an

    The Center for Advanced Subsurface Earth Resource Models (CASERM) represents a colorative venture between Mines and Virginia Tech aimed at solving research challenges in the development of 3D subsurface geological models for mineral deposits, particularly as these models integrate diverse geoscience data to inform decision making and minimize geological risk, beginning with locating and

  • Uranium: How is it Mined

    Open Pit MiningUnderground MiningMillingIn-Situ RecoverLinks to More InformationOpen pit mining, also known as strip mining, is the removal of surficial soils and uneconomic rock to get at the ore below. Ore grades are normally less than 0.5%. This is type of mining is only possible if the uranium ore is near the surface (normally less than 400 ft). The Jackpile Mine on Laguna Pueblo was once the world's largest open pit uranium mine.Waste rock or overburden (the material removed over the ore body) usua在geoinfo.nmt.edu上查看更多信息

    The Basis of Radiation Protection StandardsAchieving Effective Radiation SafetyRadiation Safety Regulation in AustraliaNotes & ReferencesIn pract, radiation protection is based on the understanding that small increases over natural levels of exposure are not likely to be harmful but should be kept to a minimum. To put this into pract, the International Commission for Radiological Protection (ICRP) has established recommended standards of protection (both for s of the public and radiation ers) based on three basic principles: 1. Justification.No pract involving exposure to radiation should be adopted unless it produces a net ben
  • Radioactive Waste Management Nuclear Waste Disposal

    Types of Radioactive WasteWhere and When Is Waste producedTreatment and ConditioningStorage and DisposalFunding Waste ManagementHow Much Waste Is producedNotes & ReferencesRadioactive waste includes any material that is either intrinsically radioactive, or has been contaminated by radioactivity, and that is deemed to have no further use. Government policy dictates whether certain materials such as used nuclear fuel and plutonium are categorised as waste.Every radionuclide has a half-life the time taken for half of its atoms to decay, and thus for it to lose half of its radioactivity. Radionuclides with long half-lives tend to be alpha and beta emitters –
  • Ecological Effects of Subsurface Mining dummies

    Subsurface mines are probably what you envision when you think of mining: systems of tunnels and vertical shafts with elevators to take miners underground where they can retrieve the valuable resources.. Subsurface mines produce large amounts of environmentally hazardous acid mine drainage.To keep the underground system of tunnels and mine shafts clear, mining companies have to pump out large
