A B Stratofortress carrying two Mark 39 nuclear bombs broke up in mid-air, dropping its nuclear payload in the process. Eight fatalities and more than 30 people were over-exposed to radiation.

The crisis is generally regarded as the moment in which the Cold War came closest to turning into a nuclear conflict [60] and is also the first documented instance of mutual assured destruction MAD being discussed as a determining factor in a major international arms agreement.

Wood River Junction criticality accident. Resulted in 1 fatality The KC was completely destroyed when its fuel load ignited, killing all four crew members. The BG broke apart, killing three of the seven crew members aboard. The non-nuclear explosives in two of the weapons detonated upon impact with the ground, resulting in the contamination of a 2-square-kilometer acre 0.

The aircraft was carrying four hydrogen bombs when a cabin fire forced the crew to abandon the aircraft.

Six crew members ejected safely, but one who did not have an ejection seat was killed while trying to bail out. The bomber crashed onto sea ice in Greenlandcausing the nuclear payload to rupture and disperse, which resulted in widespread radioactive contamination.

Soviet submarine K reactor near meltdown. On August 27, an uncontrolled increase of the reactor's power occurred following work to upgrade the vessel. One of the reactors started up automatically when the control rods were raised to a higher position. Power increased to 18 times its normal amount, while pressure and temperature levels in the reactor increased to four times the normal amount.

The automatic start-up of the reactor was caused by the incorrect installation of the control rod electrical cables and by operator error.

Radiation levels aboard the vessel deteriorated. Plutonium solution was poured into a cylindrical container with dangerous geometry.

One person died, another took a high dose of radiation and radiation sickness, after which he had two legs and his right arm amputated. Lucens reactor in Switzerland undergoes partial core meltdown leading to massive radioactive contamination of a cavern.

Columbus radiotherapy accident, 10 fatalities, 88 injuries from cobalt source. Anatoli Bugorski was working on Uthe largest Soviet particle acceleratorwhen he accidentally exposed his head directly to the proton beam. He survived, despite suffering some long-term damage.

Over 1, tons of radioactive mill waste and millions of gallons of mine effluent flowed into the Puerco Riverand contaminants traveled downstream.

Ina small capsule containing highly radioactive caesium was found inside the concrete wall of an apartment building. The accident was detected only after the residents called in a health physicist.

Houston radiotherapy accident, 7 fatalities.

Radiation accident in Moroccoeight fatalities from overexposure to radiation from a lost iridium source.The Fukushima nuclear disaster is a series of ongoing equipment failures, reactor meltdowns, and releases of radioactive materials at the Fukushima Daiichi Nuclear Power Plant, following the Tōhoku earthquake and tsunami on March 11, The plant has six separate Nuclear reactors maintained by the Tokyo Electric Power Company (TEPCO).

The accident is the second biggest nuclear accident. The accident at the Chernobyl nuclear power plant in Ukraine has been described as the worst nuclear disaster the world has ever seen.

Chernobyl Accident (Updated April ) The Chernobyl accident in was the result of a flawed reactor design that was operated with inadequately trained personnel.

Chernobyl was by far the worst nuclear power plant accident in history. The explosion and subsequent release of radioactivity forced the long-term evacuation of nearly , people from a kilometer exclusion zone surrounding the plant [1].

The Chernobyl accident is the most serious accident in the history of the nuclear industry. Indeed, the explosion that occurred on 26 April in one of the reactors of the nuclear power plant, and the consequent fires that lasted for 10 days, led to huge amounts of radioactive materials being released into the environment and a radioactive cloud spreading over much of Europe.
