One of four example estimates of the plutonium (Pu-239) plume from the 1957 fire at the Rocky Flats nuclear weapons plant. The Rocky Flats Plant, a former United States nuclear weapons production facility located about 15 miles (24 km) northwest of Denver, caused radioactive (primarily plutonium, americium, and uranium) contamination within and outside its boundaries.

The Rocky Flats Plant was a United States manufacturing complex that produced nuclear weapons parts near Denver, Colorado. [2] The facility's primary mission was the fabrication of plutonium pits, [3] the fissionable part of a bomb that produces a nuclear explosion.
After sufficient plutonium had been produced, the production reactors were shut down between 1964 and 1971. Many early safety procedures and waste disposal practices were inadequate, resulting in the release of significant amounts of radioactive materials into the air and the Columbia River, resulting in higher rates of cancer in the ...
Watchdogs are raising new concerns about legacy contamination in Los Alamos, the birthplace of the atomic bomb and home to a renewed effort to manufacture key components for nuclear weapons. A ...
Zheleznogorsk is also the location for the production of plutonium, electricity and district heat using graphite-moderated water-cooled reactors. The last reactor was shut down permanently in April 2010. [10] It is the location of a military reprocessing facility and for a Russian commercial nuclear-waste storage facility.
The fourth arming device—the pilot's safe/arm switch—was not activated, preventing detonation. The second bomb plunged into a muddy field at around 700 mph (300 m/s) and disintegrated. Its tail was discovered about 20 feet (6 m) down and much of the bomb recovered, including the tritium bottle and the plutonium. However, excavation was ...
Reddit, which went public in March, last month reported its first profit as a publicly traded company. The social media service also reported that its daily users surged 47% to 97.2 million ...
According to the Trenton Times, “In June 1987, traces of a radioactive substance used in nuclear warheads (americium-241 related to plutonium) were found about one-half mile from the site." [ 14 ] In a 1992 report, the Air Force wrote that the missile launcher from Shelter 204 had been removed from the shelter shortly after the accident, and ...
