From 1944 to 1974, the US government conducted over 4,000 radiation experiments on unwitting citizens. Plutonium was injected into 18 patients without consent, pregnant women at Vanderbilt University were fed radioactive iron, mentally disabled children at Fernald State School were fed radioactive oatmeal, and prisoners had their testicles irradiated. President Clinton's 1994 Advisory Committee documented the full scope.
