Russell worked on the Manhattan Project from 1942 to 1946 at the University of Chicago's Met Lab, researching the isolation and extraction of plutonium-239 from uranium. [3] In 1947 to 1953, Edwin served as chairman of the Division of Science at Allen University in Columbia, SC.
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 ...
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.
Doctors left his fractures untreated for 20 days until after plutonium injections began on 10 April 1945. Cade received the injections at the Oak Ridge Hospital on the Clinton Engineer Works reservation without his consent or knowledge. He became known as HP-12 (Human Product-12) and was the first person to be injected with Plutonium-239.
Within the Manhattan Project, plutonium was referred to often by its code designation "49" (from its atomic number 94 and its atomic mass 239) or simply the "product". Few outside of the Manhattan Project would have known of plutonium, much less of the dangers of radioactive isotopes inside the body.
From 1945 to 1947, 18 people were injected with plutonium by Manhattan project doctors. Ebb Cade was an unwilling participant in medical experiments that involved injection of 4.7 micrograms of plutonium on April 10, 1945 at Oak Ridge, Tennessee. [4] [5] This experiment was under the supervision of Harold Hodge. [6]
