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]
disputed. Kyshtym disaster. 1957, September 29. An improperly stored underground tank of high-level radioactive waste exploded. Death count unknown, estimates range from 50 to more than 9,000. 78. Chernobyl disaster. 1986, April 28. At least 78 are believed to have been directly killed by the disaster (31 due to the explosion, 28 due to ...

2 July 1956 – Sylvania Electric Products explosion in Queens, New York City. Explosions of thorium slugs resulted in the death by toxic heavy metal poisoning of one plant employee. [7] June, 1958 – Y-12 National Security Complex criticality incident – Eight workers injured in the incident.
The International Nuclear and Radiological Event Scale (INES) was introduced in 1990 [1] by the International Atomic Energy Agency (IAEA) in order to enable prompt communication of safety significant information in case of nuclear accidents. The scale is intended to be logarithmic, similar to the moment magnitude scale that is used to describe ...
The Three Mile Island accident was a partial nuclear meltdown of the Unit 2 reactor (TMI-2) of the Three Mile Island Nuclear Generating Station on the Susquehanna River in Londonderry Township, near Harrisburg, Pennsylvania. The reactor accident began at 4:00 a.m. on March 28, 1979, and released radioactive gases and radioactive iodine into the ...
Demon core. A re-creation of the experiment involved in the 1945 incident. The sphere of plutonium is surrounded by tungsten carbide blocks acting as neutron reflectors. The demon core was a sphere of plutonium that was involved in two fatal radiation accidents when scientists tested it as a fissile core of an early atomic bomb.
Cancer induction. Cancer induction is the most significant long-term risk of exposure to a nuclear bomb. Approximately 1 out of every 80 people exposed to 1 Gray will die from cancer, in addition to the normal rate of 20 out of 80. About 1 in 40 people will get cancer, in addition to the typical rates of 16-20 out of 40.
