Researchers in the United States have performed thousands of
human radiation experiments to determine the effects of
ionizing radiation and
radioactive contamination on the human body, generally on people who were poor, sick, or powerless. 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, such as feeding radioactive food to mentally disabled children or
conscientious objectors, inserting
radium rods into the noses of schoolchildren, deliberately releasing radioactive chemicals over U.S. and Canadian cities, measuring the health effects of
radioactive fallout from nuclear bomb tests, injecting pregnant women and babies with radioactive chemicals, and
irradiating the testicles of prison inmates, amongst other things. Much information about these programs was
classified and kept secret. In 1986, the
United States House Committee on Energy and Commerce released a report entitled
American Nuclear Guinea Pigs: Three Decades of Radiation Experiments on U.S. Citizens. 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 to monitor government tests; it published results in 1995. Welsome later wrote a book called
The Plutonium Files. Radioactive iodine experiments In a 1949 operation called the "
Green Run", the
U.S. Atomic Energy Commission (AEC) released
iodine-131 and
xenon-133 into the atmosphere near the
Hanford site in Washington, which contaminated a area containing three small towns. In 1953, the AEC ran several studies at the
University of Iowa on the health effects of radioactive iodine in newborns and pregnant women. In one study, researchers gave pregnant women between of iodine-131, and later performed abortions to study the women's embryos in an attempt to discover at what stage, and to what extent, radioactive iodine crosses the
placental barrier. In another study, they gave 25 newborn babies (who were under 36 hours old and weighed from ) iodine-131, either by oral administration or through an injection, so that they could measure the amount of iodine in their thyroid glands, as iodine would go to that gland. In 1953, the AEC sponsored a study to discover if radioactive iodine affected
premature babies differently from full-term babies. In the experiment, researchers from
Harper Hospital in Detroit orally administered iodine-131 to 65 premature and full-term infants who weighed from . In 1962, the Hanford site again released I-131, stationing test subjects along its path to record its effect on them. The AEC also recruited Hanford volunteers to ingest milk contaminated with I-131 during this time. Between 1953 and 1957, at the
Massachusetts General Hospital, Dr. William Sweet injected eleven terminally ill, comatose and semi-comatose patients with uranium in an experiment to determine, among other things, its viability as a
chemotherapy treatment against
brain tumors, which all but one of the patients had (one being a misdiagnosis). Sweet, who died in 2001, maintained that consent had been obtained from the patients and next of kin.
Plutonium experiments From April 10, 1945, to July 18, 1947, eighteen people were injected with
plutonium as part of the
Manhattan Project. Doses administered ranged from 95 to 5,900
nanocuries. had Stevens injected with
Pu-238 and
Pu-239 without informed consent. Stevens never had cancer; a surgery to remove cancerous cells was highly successful in removing the
benign tumor, and he lived for another 20 years with the injected plutonium. which keeps the remains of people who died with
radioisotopes in their body. Three patients at
Billings Hospital at the
University of Chicago were injected with plutonium. In 1946, six employees of a Chicago
metallurgical lab were given water that was contaminated with plutonium-239 so that researchers could study how plutonium is absorbed into the
digestive tract.
Experiments involving other radioactive materials Immediately after World War II, researchers at
Vanderbilt University gave 829 pregnant mothers in Tennessee what they were told were "vitamin drinks" that would improve the health of their babies. The mixtures contained radioactive iron and the researchers were determining how fast the radioisotope crossed into the
placenta. Four of the women's babies died from cancers as a result of the experiments, and the women experienced rashes, bruises, anemia, hair/tooth loss, and cancer. The
University of California Hospital in San Francisco exposed 29 patients, some with
rheumatoid arthritis, to total body irradiation (100–300 rad dose) to obtain data for the military. In the 1950s, researchers at the
Medical College of Virginia performed experiments on severe burn victims, most of them poor and black, without their knowledge or consent, with funding from the Army and in collaboration with the AEC. In the experiments, the subjects were exposed to additional burning, experimental
antibiotic treatment, and injections of radioactive isotopes. The amount of radioactive
phosphorus-32 injected into some of the patients, , was 50 times the "acceptable" dose for a healthy individual; for people with severe burns, this likely led to significantly increased death rates. Between 1948 and 1954, funded by the federal government, researchers at the
Johns Hopkins Hospital inserted
radium rods into the noses of 582
Baltimore, Maryland schoolchildren as an alternative to
adenoidectomy. Similar experiments were performed on over 7,000 U.S. Army and Navy personnel during World War II. In another study at the
Walter E. Fernald State School, in 1956, researchers gave mentally disabled children radioactive calcium and iron tracers orally and intravenously, without informing the children's parents. They also injected radioactive chemicals into malnourished babies and then collected
cerebrospinal fluid for analysis from their brains and spines. In 1961 and 1962, ten
Utah State Prison inmates had blood samples taken which were mixed with radioactive chemicals and reinjected back into their bodies. The U.S. Atomic Energy Commission funded the
Massachusetts Institute of Technology to administer
radium-224 and
thorium-234 to 20 people between 1961 and 1965. Many were chosen from the Age Center of New England and had volunteered for "research projects on aging". Doses were for radium and for thorium. Early in the
Cold War, in studies known as
Project GABRIEL and
Project SUNSHINE, researchers in the United States, the United Kingdom, and Australia tried to determine how much
nuclear fallout would be required to make the Earth uninhabitable. They realized that atmospheric
nuclear testing had provided them an opportunity to investigate this. Such tests had dispersed
radioactive contamination worldwide, and examination of human bodies could reveal how readily it was taken up and hence how much damage it caused. Of particular interest was
strontium-90 in the bones. Infants were the primary focus, as they would have had a full opportunity to absorb the new contaminants. As a result of this conclusion, researchers began a program to collect human bodies and bones from all over the world, with a particular focus on infants. The bones were cremated and the ashes analyzed for radioisotopes. This project was kept secret primarily because it would be a
public relations disaster; as a result parents and family were not told what was being done with the body parts of their relatives. These studies should not be confused with the
Baby Tooth Survey, which was undertaken during the same time period.
Irradiation experiments In 1927, five-year-old
Vertus Hardiman and nine other children from
Lyles Station, Indiana, were severely irradiated during a medical experiment conducted at the local county hospital. To get parental consent, the experiment was misrepresented as a new therapy for the scalp fungus known as
ringworm. Many of the children suffered long-term effects, but Hardiman's were the most pronounced. The radiation disfigured his head and left a large, open wound on the side of his skull. The parents of the children met with a local lawyer and filed a lawsuit against the hospital, but the hospital was found not liable. From 1960 to 1971,
Dr. Eugene Saenger, funded by the
Defense Atomic Support Agency, performed whole body radiation experiments on more than 90 poor, black, advanced stage cancer patients with inoperable tumors at the
University of Cincinnati Medical Center during the
Cincinnati Radiation Experiments. He forged consent forms, and did not inform the patients of the risks of irradiation. The patients were given 100 or more rads (1 Gy) of whole-body radiation, which in many caused intense pain and vomiting. Critics have questioned the medical rationale for this study, and contend that the main purpose of the research was to study the acute effects of radiation exposure. From 1963 to 1973, a leading
endocrinologist, Dr. Carl Heller,
irradiated the testicles of
Oregon and
Washington prisoners. In return for their participation, he gave them $5 a month, and $100 when they had to receive a
vasectomy upon conclusion of the trial. The surgeon who sterilized the men said that it was necessary to "keep from contaminating the general population with radiation-induced
mutants". Dr. Joseph Hamilton, one of the researchers who had worked with Heller on the experiments, said that the experiments "had a little of the
Buchenwald touch". In 1963,
University of Washington researchers irradiated the testicles of 232 prisoners to determine the effects of radiation on testicular function. When these inmates later left prison and had children, at least four of them had offspring born with
birth defects. The exact number is unknown because researchers never followed up on the status of the subjects. ==Chemical experiments==
