The Nevada National Security Sites (N2S2[1] or NNSS), popularized as the Nevada Test Site (NTS) until 2010, [2] is a reservation of the United States Department of Energy located in the southeastern portion of Nye County, Nevada, about 65 mi (105 km) northwest of the city of Las Vegas. Formerly known as the Nevada Proving Grounds of the United ...
13. Radiotherapy accident in Costa Rica. 1996. 114 patients received an overdose of radiation from a cobalt-60 source that was being used for radiotherapy. [13]: 299, 303. 11. Radiotherapy accident in Zaragoza, Spain. 1990 December. Cancer patients receiving radiotherapy; 11 fatalities and 27 patients were injured.
A nuclear and radiation accident is defined by the International Atomic Energy Agency (IAEA) as "an event that has led to significant consequences to people, the environment or the facility." Examples include lethal effects to individuals, large radioactivity release to the environment, or a reactor core melt. [ 6 ]
Acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation in a short period of time. [1] Symptoms can start within an hour of exposure, and can last for several months. [1][3][5] Early symptoms are usually ...
The Rocky Flats Plant, a former United States nuclear weapons production facility located about 15 miles (24 km) northwest of Denver, caused radioactive (primarily plutonium, americium, and uranium) contamination within and outside its boundaries. [ 1 ] The contamination primarily resulted from two major plutonium fires in 1957 and 1969 ...
Soldiers suffered radiation poisoning and burns. They were eventually traced back to training sources abandoned, forgotten, and unlabeled after the dissolution of the Soviet Union . One was a 137 Cs pellet in a pocket of a shared jacket which put out about 130,000 times the level of background radiation at a one-metre (3.3 ft) distance.
According to a 2010 survey of energy accidents, there have been at least 56 accidents at nuclear reactors in the United States (defined as incidents that either resulted in the loss of human life or more than US$50,000 of property damage). The most serious of these was the Three Mile Island accident in 1979.
The reported health effects are consistent with high doses of radiation, and comparable to the experiences of cancer patients undergoing radio-therapy [ 15 ] but have many other potential causes. [ 14 ] The effects included "metallic taste, erythema, nausea, vomiting, diarrhea, hair loss, deaths of pets, farm and wild animals, and damage to ...
