A re-creation of the experiment involved in the 1945 incident. The sphere of plutonium is surrounded by tungsten carbide blocks acting as neutron reflectors.. The demon core was a sphere of plutonium that was involved in two fatal radiation accidents when scientists tested it as a fissile core of an early atomic bomb.
Manhattan District The Trinity test of the Manhattan Project on 16 July 1945 was the first detonation of a nuclear weapon.

A major accident might result in loss of life and severe health effects, and Groves was concerned that even a minor one could disrupt vital war production – particularly of aluminum – or require evacuation of the Manhattan Project's isotope separation plants. But spreading the Oak Ridge facilities over a larger area would involve the ...
Over thirty small communities were removed from Soviet maps between 1958 and 1991. [67] (INES level 6) [32] October 1957: Windscale fire, UK. Fire ignites a "plutonium pile" (an air cooled, graphite moderated, uranium fuelled reactor that was used for plutonium and isotope production) and contaminates surrounding dairy farms.
Louis Alexander Slotin (/ ˈ s l oʊ t ɪ n / SLOHT-in; [1] 1 December 1910 – 30 May 1946) was a Canadian physicist and chemist who took part in the Manhattan Project.Born and raised in the North End of Winnipeg, Manitoba, Slotin earned both his Bachelor of Science and Master of Science degrees from the University of Manitoba, before obtaining his doctorate in physical chemistry at King's ...
Some real metallurgy was carried out, but the name was intended as a cover for its activities. The University of Chicago had been considering establishing a research institute into metals, and indeed would do so after the war, so its creation attracted little attention. Compton's plutonium project then became known as the Metallurgical Project ...
On July 16, 1945, Manhattan Project staff conducted the first-ever nuclear test, which, according to the National Park Service, spread radioactive fallout over an area approximately 250 miles long ...
The Plutonium Files: America's Secret Medical Experiments in the Cold War is a 1999 book by Eileen Welsome. It is a history of United States government-engineered radiation experiments on unwitting Americans, based on the Pulitzer Prize -winning series Welsome wrote for The Albuquerque Tribune .
