Researchers in the United States have performed thousands of human radiation experiments to determine the effects of atomic radiation and radioactive contamination on the human body. Most of these tests were performed, funded, or supervised by the United States military, Atomic Energy Commission, or various other U.S. federal government agencies. The experiments included a wide array of studies, involving things like feeding radioactive food to mentally disabled children, deliberately releasing radioactive chemicals over U.S. and Canadian cities, measuring the health effects of radioactive fallout from nuclear bomb tests, and irradiating the testicles of prison inmates, among other things. Much information about these programs was classified and kept secret. In the 1990s Eileen Welsome's reports on radiation testing for The Albuquerque Tribune prompted the creation of the Advisory Committee on Human Radiation Experiments by executive order of president Bill Clinton in order to monitor government tests; it published results in 1995.
