Information
has gloss	eng: The Church Rock Uranium Mill Spill occurred in New Mexico, USA, in 1979 when United Nuclear Corporation's Church Rock uranium mill tailings disposal pond breached its dam. Over 1,000 tons of radioactive mill waste and millions of gallons of mine effluent flowed into the Puerco River. Local residents used river water for irrigation and livestock and were not immediately aware of the toxic danger. In terms of the amount of radiation released the accident was comparable in magnitude to the Three Mile Island accident of the same year and has been reported as the largest radioactive accident in U.S. History.
