In February 1940, Glenn Seaborg and Edwin McMillan produced plutonium-239 by bombarding uranium with deuterons. This produced neptunium, element 93, which underwent beta-decay to form a new element, plutonium, with 94 protons. [4] Kennedy built a series of detectors and counters to verify the presence of plutonium.

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]
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 ...

Joseph Gilbert Hamilton, a Manhattan Project doctor in charge of the human experiments in California, [75] had Stevens injected with Pu-238 and Pu-239 without informed consent. Stevens never had cancer; a surgery to remove cancerous cells was highly successful in removing the benign tumor , and he lived for another 20 years with the injected ...
