Unveiled: Shocking Secret Files Expose Americans as Unwitting Test Subjects

Newly revealed declassified documents have exposed a disturbing chapter in U.S. history, where the government deliberately injected unsuspecting Americans with radioactive materials.

Between 1945 and 1947, 18 hospital patients were covertly administered plutonium as part of clandestine U.S. nuclear experiments. These experiments aimed to understand the movement and impact of radioactive substances within the human body during the early years of World War II and the Cold War.

The startling revelations first surfaced in 1995 under the Clinton administration, which directed the Department of Energy to release details of these secret experiments. The initiative sought to shed light on the radiation dangers faced by workers involved in atomic bomb production.

One of the initial victims was Ebb Cade, an African American cement worker. Following a car accident in 1945, Cade was unknowingly injected with plutonium while hospitalized.

Cade’s case was merely the tip of the iceberg. The declassified files uncovered nearly 4,000 federally sanctioned human radiation experiments carried out over three decades, from 1944 to 1974.

Most of these experiments involved low doses of radioactive tracers given to adults for medical research, which were likely harmless, but some included riskier tests like exposing children to radioisotopes or irradiating prisoners’ bodies.

Other experiments tied to national defense, such as studying soldiers’ reactions to nuclear blasts or monitoring fallout on uranium miners and residents in the Marshall Islands, often prioritized secrecy over ethics.

The fallout included immediate sickness or deaths in some cases, long-term health damage, including increased cancer chances and a deep erosion of public trust due to the lack of informed consent and government cover-ups.

Doctors attached to the Manhattan Project, the secret WWII effort to create an atom bomb that would be dropped on Japan, began work on the injection program near the end of the war and continued the project until July of 1947.

Eileen Welsome, who won a Pulitzer for her reporting on the experiments, wrote in her book The Plutonium Files: ‘One minute I was reading about beagle dogs that had been injected with large amounts of plutonium and had subsequently developed radiation sickness and tumors. Suddenly there was this reference to a human experiment. I wondered if the people had experienced the same agonizing deaths as the animals.’

Cade was in the back of a car with his brothers when their vehicle was involved in a head-on collision. 

The passengers were taken to Oak Ridge Army Hospital and Ebb was diagnosed with a fractured right kneecap, right forearm, and left femur.

Four days after the accident, a small amount of plutonium was sent to Oak Ridge and injected into Ebb’s left arm.

One of the declassified documents stated: ‘Care was taken to avoid leakage.’

Joseph Howland, Assistant Chief of Medical Research at Oak Ridge, wrote: ‘I injected a five-microcurie dose of plutonium into a human and studied his clinical experience. (I objected but in the Army, an order is an order.)’

The dose was reportedly five times larger than scientists believed could be absorbed by the the human body without causing harm and 80 times larger than what the average person absorbed in one year.

Scientists at Chicago’s Met Lab wrote: ‘Since people were of necessity exposed to some degree of plutonium and since plutonium is known to be very radiotoxic it was obviously desirable to have some method of determining whether or not a given person had any plutonium in him.’

‘Animal experiments were used to procure as much data as possible. Some human studies were needed to see how to apply the animal data to the human problems.’

Cade died at the age of 63, almost eight years to the day after he was injected. 

His brothers and sisters outlived him by decades, with one sister, Nanreen Cade Walton, living to 107.

Albert Stevens, a 58-year-old house painter diagnosed with stomach cancer and given six months to live was also injected with a large dose of plutonium during the experiments.

He secretly received a shot of Plutonium-238, an isotope 276 times more radioactive than Plutonium-239.

When doctors removed half of Stevens’s left lobe of the liver, the entire spleen, most of his ninth rib, lymph nodes, part of the pancreas, and a portion of the omentum – an apron of fat covering the internal organs – they discovered he did not have cancer.

What Stevens had was a ‘benign gastric ulcer with chronic inflammation.’

Astonishingly, despite being injected with a supposedly lethal dose of plutonium, he survived for another 21 years. 

One woman, Janet Stadt, who received radiation in the hospital died of malnutrition from cancer of the larynx, with her family only learning that she had been injected with the plutonium after being called by US Energy Secretary Hazel O’Leary in 1994.

Records show a collection of different experiments continued, with military personnel involved in tests until above-ground nuclear testing was banned decades later.

In the 1970s, cancer patients were exposed to vast doses of radiation in supposedly ‘therapeutic’ trials which also fed information to the military and led some to agonizing deaths. Children were also injected with smaller doses of radioactive tracing agents.

The experiments were conducted by Manhattan Project scientists, the Department of Energy’s Atomic Energy Commission, Pentagon officials, hospitals, and universities throughout the Cold War with the Soviet Union.

They were classified top secret to avoid public outcry, with a 1947 memo from the Atomic Energy Commission stating that information on the injections should not be released because they would have ‘an adverse effect on public opinion.’

However, it was clear from the outset that many of the scientists knew full well what they were doing.

In a classified speech in 1946, researcher Stafford Warren, inventor of the mammogram, said: ‘You need only to absorb a few micrograms of plutonium and other long-life fission materials, and then know that you are going to develop a progressive anemia or a tumor in from five to fifteen years.’

‘This is an insidious hazard and an insidious lethal effect hard to guard against.’

In 1994, the Advisory Committee on Human Radiation Experiments concluded: ‘Between 1944 and 1974 the federal government sponsored several thousand human radiation experiments.’ 

The investigation noted that even tracer dosages in amounts similar to those used today for therapeutic purposes led to severe radiation sicknesses.
