While testing out and trying to harness the power of the atomic bomb, U.S. scientists also secretly tested the bomb's effects on humans.
During the Manhattan Project, which gave way to the atomic bomb that destroyed Hiroshima and Nagasaki, U.S. scientists resorted to secret human testing via plutonium injection on 18 unsuspecting, non-consenting patients.
This included injecting soldiers with micrograms of plutonium for Project Oak Ridge along with later injecting three patients at a Chicago hospital. Imagine you're an admitted patient, helpless in a hospital bed, assuming that nothing is wrong when the government suddenly appears and puts weapons-grade plutonium in your blood.
Out of the 18 patients, who were known only by their code-names and numbers at the time, only 5 lived longer than 20 years after injection.
Along with plutonium, researchers also had fun with uranium. At a Massachusetts hospital, between 1946 and 1947, Dr. William Sweet injected 11 patients with uranium. He was funded by the Manhattan Project.
And in exchange for the uranium he received from the government, he would keep dead tissue from the body of the people he killed for scientific analysis on the effects of uranium exposure.
