Be warned, the photographs of the man’s injuries are extremely graphic. At a hospital clinic located in Zaragoza, Spain, between the dates of December 10 and December 20, 1990, at least 27 patients who were receiving radiotherapy for cancer were accidentally exposed to high levels of radiation, which resulted in the deaths of 11 patients, and severe injuries to the others. The camera is essentially a metal box with a “source pigtail” which is a pencil-length long braided metal connector that looks nothing at all like something anyone would think contains radioactivity. [1] Scott transported the plutonium from the lab to the hospital where Albert Stevens was being treated for stomach cancer. Plutonium was handled extensively by chemists, technicians, and physicists taking part in the Manhattan Project, but the effects of plutonium exposure on the human body were largely unknown. This amount is beyond the average 300+ millirems of natural sources of radiation and any medical radiation a person has received. You also need to understand the different types of radiation. While there, one of the men sitting in the car draped his one leg over the unit. He was exposed to high levels of radiation and died only a month later. The source became separated from the shielded container used to store it, and the source itself had no markings indicating it was radioactive. This led to the contamination of hundreds of people as well as the environment, which resulted in a six-month radiation clean up. At very low doses of radiation disease, the body reacts to the disease and diarrhea, and sometimes hair loss. That end of the source pigtail is then connected to drive cable. The catheter containing the source was removed from the woman and disposed of as normal medical waste. The third man died six months later. Some of the ashes were transferred to the National Human Radiobiology Tissue Repository at Washington State University,[1] which keeps the remains of people who died having radioisotopes in their body. Some of the contaminated table parts had already been made into finished tables and had to be retrieved from restaurants. [5] Kenneth Scott analyzed the samples, but he never told Stevens the true reason for collecting them; he also recalled that Stevens's sister was a nurse and quite suspicious. [1] When the hospital's pathologist analyzed the materials removed from Stevens during surgery, a startling conclusion was made: Stevens had no cancer. However, radiation is also deadly to humans when not handled properly. The Manhattan Project built mass scale production facilities for the war effort. The subsequent Nuclear Regulatory Commission (NRC) investigation found that 94 individuals at the center, the nursing home and the waste disposal company had been exposed to radiation. When specimens were taken during Stevens's cancer surgery, Earl Miller took them for radiological testing; Scott collected urine and stool samples. Soon a radiographer arrived to take radiographs of the welds and the pipe in order to ensure the pipe was safe to conduct hydrostatic testing. In addition, from sitting on his pants, his wife had a small radioactive burn on her buttock. In 1945, human tracer experiments began with the intent to determine how to properly analyze excretion samples to estimate body burden. The wife noticed a red spot on his thigh and the man went to a local doctor who told him he had a bug bite. [2][8], None of the people at U.C.S.F. Consumer Products Building and road construction materials The error went unnoticed because the staff did not conduct routine inventory checks of all radioactive sources. Slotin was exposed to almost 1,000 rads of radiation, far more than his six other colleagues who survived. Natural background radiation. Before he left work he began to notice a pain in his right thigh. On December 6, 1983, a used metal teletherapy unit (pictured) containing a source container with about 6,000, one-millimeter pellets, each with radioactive cobalt 60, was deliberately opened in a scrap yard in Ciudad Juarez, Mexico. But it was too late for the welder. He was taken for special medical treatment in Minsk, Russia, but died 113 days later. They then gave up and decided to take the unit to a scrap yard. By the time a rescue team was able to move him from the accident site, Ouchi had been exposed to seventeen sieverts of radiation, more than twice what is commonly considered a fatal level of exposure. The patient died 93 hours later, at her nursing home, from exposure to radiation from the source. However, upon examining the radiation injuries of another family member, a physician realized they were all related to radioactivity. As to man made radiation, for most people, 96 percent is from medical X-rays – a chest X-ray delivers 10 mrem, a full-body CT scan 1,000 mrem, and a dental X-ray 1.5 mrem. At the scrap yard, the men asked the scrap yard employee to use a torch to cut open the unit, which he did. [1] About 10 years after the injection, a "radiologist noted 'rather marked' degeneration in the lumbar region of his spine and several degenerating discs. Plutonium was first synthesized in 1940 and isolated in 1941 by chemists at the University of California, Berkeley. hospital and receive free gastro-intestinal lab work by Dr. Robert Stone, a radiologist who performed extensive human experiments in the 1940s. Radiation sickness is not caused by common imaging tests that use low-dose radiation, such as X-rays or CT scans.Although radiation sickness is serious and often fatal, it's rare. On the morning of February 20, 1999, a welder and his assistant began to conduct repairs on a pipe. The tele therapy unit had been taken out of service by the hospital many years previously, and had been in storage, along with several other pieces of radioactive machinery, in another location. The pigtail is inserted into the camera with one end protruding slightly. The device was taken out of service and disposed of, in 1996. They were able to open the container and expose themselves to the radiation from the source. According to Earl Miller, acting chief of radiology at the time, he was chosen for this study because "he was doomed" to die. Left unsecured for two years, it was eventually located by scrap hunters scavenging for metal. Due to their levels of radioactivity, her papers from the 1890’s are considered too dangerous to handle. Her laboratory is preserved at the Musee Curie. The hazards of radiation have not always been acknowledged. After aggressive treatment in Peru, the man was flown to France for some of the most cutting edge treatment available. [2] According to Kenneth Scott, a scientist who worked at the U.C. It weighed about 280 pounds. Historical Hazards of Radiation 1. [1], According to Stevens's surviving son Thomas, Stevens kept samples in a shed behind his house for storage; an intern and a nurse would pick them up once a week. Tragically, this was not the first, nor would it be the last incident involving a source which had become stuck in such a facility. Albert Stevens (1887–1966), also known as patient CAL-1, was a victim of a human radiation experiment, and survived the highest known accumulated radiation dose in any human. [5] The injection consisted of 0.2 micrograms of 238Pu and 0.75 micrograms of 239Pu. Australians are constantly exposed to ionising radiation from a variety of natural and artificial sources. "[6] The hospital staff reacted with disbelief. The Manhattan District decided to pay for his urine and stool samples to keep him close to San Francisco on the pretext that his "cancer" surgery and remarkable recovery were being studied. The unit was started again the following day, December 10.

Our daughters received a hundred times more radiation while camping a few days in Glacier National Park. While he was gone the wife breastfed their infant child and two other young children played in the area where the pants, and the pigtail in the pocket, were laying on the floor. But, by then, many patients had been exposed to higher than expected, and unsafe, levels of radiation. On May 14, 1945, he was injected with 131 kBq (3.55 µCi) of plutonium without his knowledge or informed consent.. Before the error was caught in September, 1996, 115 patients who had been treated using the instrument had been exposed to significantly higher levels of radiation than expected. Listed in chronological order, here are ten more examples of tragedies involving radioactive materials that resulted in death. Chen Lu had already been experimenting for … In August, 1996, a radioactive cobalt-60 source was replaced in an Alcyon II radiotherapy instrument, at the San Juan de Dios Hospital, in San Juan, Costa Rica. The opportunity to select a human patient was relatively easy: Hamilton was not only a physicist assigned to U.C. Soon afterward, the penetrating properties of the rays began to be exploited for medical purposes, with no inkling that such radiation might have deleterious effects. For example, polonium (another alpha emitter) research indicated that test sample contamination was a major concern, which is why a cleanroom had to be established at Los Alamos in February 1945 in the Medical Labs Building.[2]. He bypassed the safety systems designed to prevent an operator from being exposed, and came up with procedures so that he could enter the irradiation room and free the blockage. In addition, the husband of the scrap yard owner died of his injuries. All of the patients showed classic signs and symptoms of over exposure to radiation. Radiation Levels: Cosmic Radiation. A second employee of this scrap yard was positioned behind the employee who used the torch to cut thorough the stainless steel box and lead cylinder. In general, the following man-made sources expose the public to radiation: Medical Exposures (by far, the most significant man-made source) Diagnostic x-rays; Nuclear medicine procedures (iodine-131, cesium-137, technetium-99m etc.) However, the extent of his injuries are so severe there is little doubt that if he is still alive, he will eventually die as a result. Not knowing what they had, the scavengers took the unit home, tried to open it and in the process, damaged the cesium-137 source. The affected patients immediately suffered skin burns and effects to internal organs and their bone marrow. Later calculations would estimate the over exposure at 50-60% greater levels of radiation than intended. The applicability of risk estimates based on studies of external radiation exposure to a population exposed mainly to internal sources, and to I-131 in particular, has been debated for many years. [2] During this time, cancer researchers were attempting to discover whether certain radioactive elements might be useful to treat cancer. Inside the metal container was a radioactive source. The treating physician noticed the people were suffering from apparent radiation exposure, and contacted Thailand authorities who dispatched two health physicists to investigate. Within the Manhattan Project, plutonium was referred to often by its code designation "49" (from its atomic number 94 and its atomic mass 239) or simply the "product." Unlike the case of radium, which can be detected quite easily, there are no gamma rays to detect from outside the body. The first reports of X-ray injury to human tissue came later in 1896. One of the findings of the 1975 study was that Stevens and five others injected with plutonium had endured "doses high enough to be considered carcinogenic. [1], Stevens was injected with a mixture of plutonium isotopes having the Pu(VI) chemical species (Pu+6) as the nitrate PuO2(NO3)2. I included the Yanango incident even though, as far as I have been able to determine, the exposed man has not yet died. He was exposed to deadly gamma and neutron radiation that flashed in a blue blaze. This did not happen in the Mayapuri event, and orphan sources, as we have seen, are potentially deadly. Had all of the plutonium given to Stevens been the long-lived Pu-239 as used in similar experiments of the time, Stevens's lifetime dose would have been significantly smaller. The radiation exposure killed one of the three brothers, and led to the exposure of many others. The hospital manager blamed the technician, and the Spanish Health Minister blamed GE, the manufacturer of the instrument. The man said his hands felt “itchy” while holding the pieces. A high energy cobalt-60 radioactive source was being used at just such a plant in Soreq, Israel, in June, 1990, when the source used in the irradiation process became stuck in its rack. The sun is a major source of cosmic radiation, or radiation originating from space.Airline flights and skiing at high altitudes are activities that will increase exposure to this cosmic radiation. an average of 5.7 μSv/h. The Spanish Nuclear Safety Board inspected the unit, and found the power of the electron accelerator was set too high, and it was taken out of service on December 20, 1990. [1] On May 14, 1945, he was injected with 131 kBq (3.55 µCi) of plutonium without his knowledge or informed consent.[2]. They lived from six days up to 44 years past the time of their injection. Only "occupationally" exposed workers are included in the summary data presented here. [1] Thomas Stevens, Albert's son, always filled out medical forms indicating that there was a "history of cancer" in his family because his father had been led to believe that the "treatment" for his cancer had worked.[1]. All of the pieces of the source were eventually recovered in mid-April, and sent to a nuclear power station. There is no evidence that Stevens had any idea that he was the subject of a secret government experiment in which he would be subjected to a substance that would have no benefit to his health. Radiation - Radiation - Historical background: Within weeks after Röntgen revealed the first X-ray photographs in January 1896, news of the discovery spread throughout the world. By July, 1997, nine months after the accident, 42 of those patients had died. Pulitzer Prize–winning author Eileen Welsome wrote extensively about Stevens and other unwitting subjects of similar experiments in The Plutonium Files: America's Secret Medical Experiments in the Cold War in 1999. In the process, all three received high doses of radiation. * People are exposed to natural radiation of 2-3 mSv a year. The amounts of radiation were trivial. He had checked into the University of California Hospital in San Francisco with a gastric ulcer that was misdiagnosed as terminal cancer. There had been no reason for surgery, although the size of the inflammation was extraordinary. The amount of radiation absorbed by the body — the absorbed dose — determines how sick you'll be.Radiation sickness is also called acute radiation syndrome or radiation poisoning. Tragically, many of these incidents (though not all) occur in underdeveloped countries, through the recycling and sale of scrap metal. [2] A few mishaps in 1944 had caused certain alarm amongst project leaders, and contamination was becoming a major problem in and outside the laboratories. Over time, the radioactive source was handled by multiple people, and led to the exposure to high levels of radiation of at least 245 people. We know that the human body can repair itself after damage done by low levels of radiation. Plutonium solution was poured into a cylindrical container with dangerous geometry. Of the three nuclear weapons made during the war, two of them used plutonium as their fissile material. After the thunder god Thor thwarted a Chinese military incursion into India, the Chinese government called upon its scientists and military strategists for a way to retaliate against Thor. The source was used to radiograph welds – a non destructive analysis where ionizing radiation is used to look for defects in the metal that cannot be seen any other way. Plutonium remained present in his body for the remainder of his life, the amount decaying slowly through radioactive decay and biological elimination. As a result, the operator entered the room and was, himself, irradiated. In fact, the source pigtail contained an iridium-192 radioactive source. However, no bone tumors have yet appeared. In October, 1991, in Nesvizh, Belarus, a cobalt-60 source became jammed in the product transport system and the operator entered the facility to clear the blockage, once again, bypassing several safety systems. The source became active for about one minute and the operator was exposed to high levels of radiation as a result. [2] Eight of the 18 died within two years of the injection. Eventually, three of these units were moved to a garage and it was there that the one tele therapy unit was stolen for sale as scrap metal. The female owner of the scrap yard came out and ordered the men to take the unit back to their house, and continue working on it there. Numerous analytic methods were devised by the lead doctors at the Met Lab (Chicago), Los Alamos, Rochester, Oak Ridge, and Berkeley. However, scientists are unsure whether low levels of radiation dosage are really harmful to us or not. As a result of cutting the source into pieces, eight people were hospitalized due to radiation exposure, and one died. While most cosmic radiation is absorbed by the atmosphere, a small amount reaches the earth's surface to which we are exposed. Authorities then spent many days carefully removing pieces of scrap metal until they were finally able to locate the actual source and safely remove it. While at the hospital, "both a radiologist and a surgical consultant concluded that Albert probably had cancer but suggested a gastroscopy be done to confirm the diagnosis. People exposed to low levels of radiation face increased risk of cancer. As long as a person is alive, the simplest way to detect plutonium would be to analyze a person's excretion through urine and feces. Dr. Chen Lu was a respected nuclear physicist for the People's Republic of China. By mid February all had developed signs of radiation sickness, and had been admitted to hospitals. The last fatality occurred on December 25, 1991. 4 at the Chernobyl Nuclear Power Plant, near the now-abandoned town of Pripyat, in Northern Soviet Ukraine, on 25th and 26th of April 1986, remains the worst nuclear disaster in human history. Inside they found a metal container and removed it from the facility. Somehow, the pigtail fell out of the camera (there were locks in place that should have prevented this from happening, but still, the pigtail fell out). Later, the plant operator came to the man’s house asking if he had seen the missing source. The device involved in this incident was a Gammatron-3 teletherapy unit, originally installed in a Bangkok, Thailand, hospital, in 1969. "[6], Tracer experiments were begun in 1944 with rats and other animals with the knowledge of all of the Manhattan project managers and health directors of the various sites. The cobalt-60 radioactive source was cut into several pieces by the scrap metal workers, one of whom took a piece and put it in his wallet. Radioactive sources have many uses, and not just for medical purposes. Turn autoplay off. In Sinola, Mexico, authorities had to destroy 109 homes that had been built with the contaminated rebar. Eighteen people aged 4 to 69 were injected with plutonium. How much radiation exposure can I get from building materials? TEPCO found radiation of 25 sieverts an hour on a duct, which connects reactor buildings and the 120-meter-tall ventilation pipe. In November 1943, the X-10 Graphite Reactor at the Oak Ridge National Laboratory began producing significant amounts of the element, and industrial–scale production began in March 1945 with the commissioning of the B Reactor at the Hanford Site in Washington State. Few outside of the Manhattan Project would have known of plutonium, much less of the dangers of radioactive isotopes inside the body. * In a CT scan, the organ being studied typically receives a radiation dose of 15 mSv in an adult to 30 mSv in a newborn infant. The first patient died on February 16, 1991. Along with a fourth man, they drove the unit to the scrap yard, but first stopped at one man’s home. She is interred at the cemetery in Sceaux, alongside her husband Pierre. [2], As the Manhattan Project continued to use plutonium, airborne contamination began to be a major concern. It comes from rocks, walls, earth, sun, and nothing warmer than 0 degrees emit radiation. Building materials that are made up of sandstone, concrete, brick, natural stone, gypsum, and granite are highly unlikely to contain radioactive material that will increase radiation dose above the low levels of background radiation … One of these subsequently died from their injuries. [1] The annual, whole-body dose currently permitted to radiation workers in the United States is 5 rem;[10] Steven's total dose was approximately 60 times this amount. Radiation levels aboard the vessel deteriorated. The pellets were scattered throughout the scrap yard, and a magnetic loader further dispersed the radioactive pellets, when the scrap metal was converted to steel products on December 10, 1983. Stevens received approximately 6400 rem (64 Sv) in the 20 years after his injection, or about 300 rem (3 Sv) per year. [8] This was then converted to the bone's surface dose, which was 7,420 rad. Turn … [2], Plutonium-238 and plutonium-239 are exceedingly difficult to detect inside the body because they are alpha particle emitters. San Francisco. This time the orphaned source was an iridium-132 source. The welder continued to work for another three hours, then boarded a bus with multiple other workers and went home. Nonetheless, most people are not aware of all the natural and man-made sources of radiation in our environment. On January 24, 2000, two men purchased the tele therapy unit as scrap metal, and drove it through Bangkok to their home. Elihu Thomson, an American electrical engineer, deliberately exposed … Shortly after the article was published in November 1993, the Secretary of Energy, Hazel O'Leary, publicly stated that the government should compensate victims. The legs and feet of two of the men were so burned by the radiation that they had to be amputated. Large accidents and disasters, like the Chernobyl nuclear reactor explosion and the Fukushima Japan nuclear power plant catastrophe, get the headlines and, justifiably, make the public nervous about the use of radioactive fuel to generate electricity in nuclear power plants. Others are related to industrial accidents, and even medical treatment errors. One person died, another took a high dose of radiation and radiation sickness, after which he had two legs and his right arm amputated. In a 1975 study of the eighteen people who received plutonium injections in Manhattan Project experiments, CAL-1 (Albert Stevens) was shown to have received by far the highest dose to his bones and liver, calculated as 580 and 1460 rad, respectively. or those who treated Stevens ever explained to Stevens that he did not have cancer, nor did they disclose to him that he was a part of an experiment; his wife and daughter "figured they were using him for a guinea pig," but that the experimental treatment had worked. The current annual permitted dose for a radiation worker in the United States is 0.05 Sv (or 5 rem), i.e. Once Stevens was out of surgery, his urine and stool samples were analyzed for plutonium activity. On September 13, 1987, at Goiania, Brazil, a radioactive source was removed from an abandoned hospital in the city. The man, who was in his 50s, died of lung cancer as a result of being exposed to radiation, Japanese national broadcaster NHK reports. Consider these five examples of what happens when we fail to practice precaution when it comes to ionizing radiation, lessons that may prove valuable when we consider the proliferation of non-ionizing radiation. Radiation exposure levels are worsening in Japan. In some cases, a few of these people die as a result of accidental exposure to high radiation levels. [2], The plutonium experiments were not isolated events. There had also been no therapeutic intent for the experiment,[6][9] although surgeons assumed that Stevens had received radioactive phosphorus for "special studies."[1]. Twenty of those showed sign of radiation exposure and needed hospital treatment. They come from radio and television broadcasts, WiFi and Bluetooth devices, cell phones (and cell phone towers), and other sources. The tele therapy unit has a source holder and shield made from lead, and surrounded by stainless steel. * People are constantly exposed to some level of natural radiation. [8] The fact that he had the highly radioactive Pu-238 (produced in the 60-inch cyclotron at the Crocker Laboratory by deuteron bombardment of natural uranium)[8] contributed heavily to his long-term dose. Radioactivity, especially radioactivity used in cancer treatment and diagnostic testing, saves the lives of thousands of people every year. Any increase in cancer risk depends on radiation dose - increasing dose = increasing risk. Later the pigtail was safely retrieved and the street and house decontaminated. We are all exposed to radiation levels in our daily life. Stevens died of heart disease some 20 years later, having accumulated an effective radiation dose of 64 Sv (6400 rem) over that period, i.e. The service man who repaired the instrument incorrectly increased output power, so patients that should have received therapy at 7 million electron volts (MeV) were instead treated at 40 MeV. An aerial survey of the Ciudad Juarez area in March of that year, located 21 contaminated zones including a pickup truck with children playing on it. At least four people died. The welders resumed their work. Thyroid cancer risks from external radiation are related to gender and to age at exposure, with by far the highest risks occurring among women exposed as young children. He is one of the two fatalities of Tokaimura nuclear accident that exposed him to, perhaps, the highest amount of radiation any human had exposed so far. San Francisco radiologist Earl Miller injected the plutonium into Albert's body. [6] Hamilton had been experimenting on people (including himself) since the 1930s at Berkeley. But the radiation won't linger in your body, it's not going to make you "glow".. What can become a danger for others is radioactive dust or particles that stick to your clothes and skin.By hugging or touching somebody you could transfer that radioactive material. In November, 1992, an 82 year old patient was undergoing brachytherapy radiotherapy treatment at the Indiana, Pennsylvania, Regional Cancer Center. The plutonium produced by the B-reactor was earmarked for the implosion-type, plutonium cored nuclear weapons that were being developed as part of the Manhattan Project.
