Church Rock Uranium Mill Spill
The Church Rock uranium mill spill occurred in the U.S. state of New Mexico on July 16, 1979, when United Nuclear Corporation's tailings disposal pond at its uranium mill in Church Rock breached its dam. The accident remains the largest release of radioactive material in U.S. history, having released more radioactivity than the Three Mile Island accident four months earlier. The mill, which operated from June 1977 to May 1982, was located on privately owned land about north of Gallup, New Mexico, and was bordered to the north and southwest by Navajo Nation Tribal Trust lands. The milling of uranium ore produced an acidic slurry of ground waste rock and fluid (tailings) that was pumped to the tailings disposal area. The breach released more than of solid radioactive mill waste and of acidic, radioactive tailings solution into the Puerco River through Pipeline Arroyo. An estimated of uranium and 46 curies of alpha contaminants traveled downstream to Navajo County, Arizona, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Effects Of The Chernobyl Disaster
The 1986 Chernobyl disaster triggered the release of radioactive contamination into the atmosphere in the form of both particulate and gaseous radioisotopes. , it was the world's largest known release of radioactivity into the environment. The work of the Scientific Committee on Problems of the Environment (SCOPE), suggests that the Chernobyl incident cannot be directly compared to atmospheric tests of nuclear weapons by simply saying that it's better or worse. This is partly because the isotopes released at Chernobyl tended to be longer-lived than those released by the detonation of atomic bombs. The economic damage caused by the disaster is estimated at $225 billion. Radiation effects on humans According to a 2009 United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) study, the Chernobyl accident had by 2005 caused 61,200 man- Sv of radiation exposure to recovery workers and evacuees, 125,000 man-Sv to the populace of Ukraine, Belarus, and R ...

Chernobyl Disaster
The Chernobyl disaster was a nuclear accident that occurred on 26 April 1986 at the No. 4 reactor in the Chernobyl Nuclear Power Plant, near the city of Pripyat in the north of the Ukrainian SSR in the Soviet Union. It is one of only two nuclear energy accidents rated at seven—the maximum severity—on the International Nuclear Event Scale, the other being the 2011 Fukushima nuclear disaster in Japan. The initial emergency response, together with later decontamination of the environment, involved more than 500,000 personnel and cost an estimated 18 billion roubles—roughly US$68 billion in 2019, adjusted for inflation. The accident occurred during a safety test meant to measure the ability of the steam turbine to power the emergency feedwater pumps of an RBMK-type nuclear reactor in the event of a simultaneous loss of external power and major coolant leak. During a planned decrease of reactor power in preparation for the test, the operators accidentally drop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goiânia Accident
The Goiânia accident was a radioactive contamination accident that occurred on September 13, 1987, in Goiânia, Goiás, Brazil, after a forgotten radiotherapy source was stolen from an abandoned hospital site in the city. It was subsequently handled by many people, resulting in four deaths. About 112,000 people were examined for radioactive contamination and 249 of them were found to have been contaminated. In the consequent cleanup operation, topsoil had to be removed from several sites, and several houses were demolished. All the objects from within those houses, including personal possessions, were seized and incinerated. ''Time'' magazine has identified the accident as one of the world's "worst nuclear disasters" and the International Atomic Energy Agency (IAEA) called it "one of the world's worst radiological incidents". Description of the source The radiation source in the Goiânia accident was a small capsule containing about of highly radioactive caesium chlori ...

1990 Clinic Of Zaragoza Radiotherapy Accident
The 1990 Clinic of Zaragoza radiotherapy accident was a radiological accident that occurred from 10 to 20 December 1990, at the Clinic of Zaragoza, in Aragon, Spain. In the accident, at least 27 patients were injured, and 11 of them died due to the overexposure, according to International Atomic Energy Agency (IAEA). All of the injured were cancer patients receiving external beam radiotherapy. Chronology On 7 December 1990, a technician performed maintenance on an electron accelerator at the Clinic of Zaragoza. On 10 December, it returned to service after the repairs. Affected patients immediately suffered burns on the skin of the irradiated area, as well as inflammation of the internal organs and bone marrow. The first overexposed patient died on 16 February 1991, two months after irradiation. Fatalities increased until, on 25 December 1991, the last of a total of 25 patients died. The IAEA established that 11 of the deaths were due to the faulty maintenance. On 19 December ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1996 San Juan De Dios Radiotherapy Accident
The radiotherapy accident in Costa Rica occurred with the Alcyon II radiotherapy unit at San Juan de Dios Hospital in San José, Costa Rica. It was related to a cobalt-60 source that was being used for radiotherapy in 1996. An accidental overexposure of radiotherapy patients treated during August and September 1996 was detected. During the calibration process done after the change of 60Co source on 22 August 1996, a mistake was made in calculating the dose rate, leading to severe overexposure of patients. The error of calibration was detected on 27 December 1997. In the course of the accident, 114 patients received an overdose of radiation and 13 died of radiation-related injuries. In 2001, the radiophysicist whose mistake caused the radiation overdoses was charged with 16 culpable homicides and sentenced to six years in prison.

Tokaimura Nuclear Accident
There have been two noteworthy nuclear accidents at the Tōkai village nuclear campus, Ibaraki Prefecture, Japan. The first accident occurred on 11 March 1997, producing an explosion after an experimental batch of solidified nuclear waste caught fire at the Power Reactor and Nuclear Fuel Development Corporation (PNC) radioactive waste bituminisation facility. Over twenty people were exposed to radiation. The second was a criticality accident at a separate fuel reprocessing facility belonging to Japan Nuclear Fuel Conversion Co. (JCO) on 30 September 1999 due to improper handling of liquid uranium fuel. The incident spanned approximately 20 hours and resulted in radiation exposure for 667 people and the death of two workers. Nuclear power in Japan Nuclear power was an important energy alternative for natural-resource-poor Japan to limit dependence on imported energy, providing approximately 30% of Japan’s electricity up until the Fukushima nuclear disaster of 2011, a ...

Fukushima Daiichi Nuclear Disaster
The was a nuclear accident in 2011 at the Fukushima Daiichi Nuclear Power Plant in Ōkuma, Fukushima, Japan. The proximate cause of the disaster was the 2011 Tōhoku earthquake and tsunami, which occurred on the afternoon of 11 March 2011 and remains the most powerful earthquake ever recorded in Japan. The earthquake triggered a powerful tsunami, with 13–14-meter-high waves damaging the nuclear power plant's emergency diesel generators, leading to a loss of electric power. The result was the most severe nuclear accident since the Chernobyl disaster in 1986, classified as level seven on the International Nuclear Event Scale (INES) after initially being classified as level five, and thus joining Chernobyl as the only other accident to receive such classification. While the 1957 explosion at the Mayak facility was the second worst by radioactivity released, the INES ranks incidents by impact on population, so Chernobyl (335,000 people evacuated) and Fukushima (154,000 evacu ...

Airborne Radioactivity Increase In Europe In Autumn 2017
Airborne radioactivity was detected in Europe during autumn 2017, starting from the last days of September. The source is widely suspected to be in Russia; the Russian government, however, denies that any nuclear mishaps occurred that could have caused the radiation spike. The radioactive isotope detected was ruthenium-106; across Europe, it was found to be in small quantities (from microbecquerels to a few millibecquerels per cubic metre of air), not significant for the health of the population far away from the source. It is estimated, however, that the radiation released posed a danger to any employees or residents within several kilometers of the currently unknown source. Radioactivity detected European monitoring networks declared increased radioactivity levels in Europe, coming from Eastern Europe, in the first days of October: * the Swiss Federal Office of Public Health (FOPH) reported increase of radioactive particles of ruthenium-106 from 25 September * The Institute ...
