The experiments began in 1945, when Manhattan Project scientists were preparing to detonate the first atomic bomb. Radiation was known to be dangerous and the experiments were designed to ascertain the detailed effect of radiation on human health. Most of the subjects, Welsome says, were poor, powerless, and sick.
Joseph G. Hamilton was the primary researcher for the human plutonium experiments done at U.C. San Francisco from 1944 to 1947. [1] Hamilton wrote a memo in 1950 discouraging further human experiments because the AEC would be left open "to considerable criticism," since the experiments as proposed had "a little of the Buchenwald touch."
Behind this human experiment with plutonium was Dr. Joseph Gilbert Hamilton, a Manhattan Project doctor in charge of the human experiments in California. [8] Hamilton had been experimenting on people (including himself) since the 1930s at Berkeley. He was working with other Manhattan Project doctors to perform toxicity studies on plutonium.

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.
The 1945 photo shows Manhattan Project physicist Harold Agnew holding the heart of one of the most devastating weapons in the world.
Concern was expressed over the safety of Manhattan Project laboratory personnel working with newly isolated plutonium in 1944. Hamilton led a team to conduct toxicity experiments on rats. Finding the results unsatisfactory, Hamilton participated in the decision to continue the trials with human subjects.
The Manhattan Project National Historical Park includes historic B Reactor at the Hanford nuclear site. It is open for bus tours for part of 2024. Tours will be offered only until construction ...
