On March 28, 1941, Seaborg, physicist Emilio Segrè, and Kennedy demonstrated not only the presence of plutonium, but that it was also fissile, an important distinction that was crucial to the decisions made in directing Manhattan Project research. Arthur Wahl then began exploring the chemistry of the newly discovered element. [5]
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 ...

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 ...
The 1945 photo shows Manhattan Project physicist Harold Agnew holding the heart of one of the most devastating weapons in the world.
The demon core (like the core used in the bombing of Nagasaki) was, when assembled, a solid 6.2-kilogram (14 lb) sphere measuring 8.9 centimeters (3.5 in) in diameter.. It consisted of three parts made of plutonium-gallium: two hemispheres and an anti-jet ring, designed to keep neutron flux from "jetting" out of the joined surface between the hemispheres during implosi
The project was a key part of the Manhattan Project, the United States nuclear weapons development program during World War II. Its purpose was to convert natural (not isotopically enriched) uranium metal into plutonium-239 by neutron activation , as plutonium is simpler to chemically separate from spent fuel assemblies, for use in nuclear ...
Plutonium was handled extensively by chemists, technicians, and physicists taking part in the Manhattan Project, but the effects of plutonium exposure on the human body were largely unknown. [2] A few mishaps in 1944 had caused certain alarm amongst project leaders, and contamination was becoming a major problem in and outside the laboratories. [2]
