Proposed Radioactive Waste Site in Nevada

400728 04: A "no trespassing" sign warns people to stay away from the proposed nuclear waste dump site of Yucca Mountain (L) February 7, 2002 at Nellis Air Force Base, located approximately 90 miles north of Las Vegas, NV. In January, the U.S. Department of Energy endorsed a plan to transport vast amounts of radioactive waste from nuclear power plants across the nation for burial under Yucca Mountain, where it will take 10,000 years to decay. U.S. President George W. Bush could annouce his support for the plan, which is opposed by many in Nevada, as early as this week. (Photo by David McNew/Getty Images)
