The Radiation Experiments
On March 24, 1945, a black, 53-year-old cement worker named Ebb Cade had a car accident near Oak Ridge, Tennessee. Suffering from broken bones in his right arm and both legs, Cade was taken to the nearby Manhattan Project Army Hospital. Because Cade’s injuries required several operations to properly set the bones, he was kept in the hospital for a few weeks. It was long enough, also, for Cade-code-named “HP [human product] 1”—to become the first of eighteen patients to be injected with plutonium, 4.7 micrograms, on April 10, 1945.
