Locality: Hanford Site area, Benton County, Washington, U.S.A.
Nine reactors were eventually built along the Columbia River, and Hanford produced nearly two-thirds of the plutonium used in the U.S. nuclear weapons stockpile. Since the 1989 Tri-Party Agreement between the U.S. Department of Energy, the EPA and the Washington State Department of Ecology, the site's main mission has been cleanup. Today the Hanford Site is managed by the U.S. Department of Energy as one of the largest environmental cleanup projects in the country; Energy Northwest's Columbia Generating Station, a commercial nuclear power plant, operates on land leased from DOE at the site. B Reactor has been preserved as a National Historic Landmark and is part of the Manhattan Project National Historical Park.
The Hanford Site in southeastern Washington was established in 1943 as part of the Manhattan Project to produce plutonium. Its B Reactor, built by DuPont from designs tested by Enrico Fermi, was the world's first full-scale plutonium production reactor. Plutonium made there was used in the Trinity test on July 16, 1945, and in the atomic bomb dropped on Nagasaki on August 9, 1945.
Leaded glass, like lead crystal glassware, starts out clear and colourless, which is why it is widely used for windows in radiation shields. According to the Oak Ridge Associated Universities radiation museum, prolonged radiation exposure turns ordinary leaded glass dark amber-brown. Adding a small amount of cerium prevents this darkening but gives the glass a yellowish colour.
Hanford glass is sold as leaded shielding-window glass from a hot cell at the Hanford Site in Washington, U.S.A., though the history of an individual piece can't be independently documented. Hot cells are heavily shielded rooms where workers handled radioactive materials remotely, watching through thick viewing windows built from layers of dense lead glass. Radiation gradually darkens ordinary lead glass to amber-brown. A yellow tint in shielding glass usually comes from added cerium, which helps the glass resist that darkening. It is a man-made industrial glass, not a natural mineral.
Contains a high level of lead oxide. Handle with care, wash your hands after handling, and keep away from children and pets. Not for jewellery or skin contact.
