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 ...
Downwinders. Downwinders were individuals and communities in the intermountain West between the Cascade and Rocky Mountain ranges primarily in Arizona, Nevada, New Mexico, and Utah but also in Oregon, Washington, and Idaho who were exposed to radioactive contamination or nuclear fallout from atmospheric or underground nuclear weapons testing ...
Radiation poisoning, also called "radiation sickness" or a "creeping dose", is a form of damage to organ tissue due to excessive exposure to ionizing radiation. The term is generally used to refer to acute problems caused by a large dosage of radiation in a short period, though this also has occurred with long-term exposure to low-level radiation.
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 ]
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 ...
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. As of 2024, it was the world's largest known release of radioactivity into the environment.
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.
On 19 June 2012 Minister of Science Hirofumi Hirano said that Japan would review the decision of the Science Ministry and the Nuclear-Safety Agency in 2011 to ignore the radiation maps provided by the United States. He defended his ministry's handling of the matter with the remark that its task was to measure radiation levels on land.
