In listing civilian radiation accidents, the following criteria have been followed: There must be well-attested and substantial health damage, property damage or contamination. The damage must be related directly to radioactive materials or ionizing radiation from a man-made source, not merely taking place at a facility where such are being used.
In listing civilian nuclear accidents, the following criteria have been followed: Notably severe: there must be well-attested and substantial health damage, property damage or contamination; if an International Nuclear Event Scale (INES) level is available, of at least two.
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 Windscale fire resulted when uranium metal fuel ignited inside plutonium production piles; surrounding dairy farms were contaminated. [33] [34] The severity of the incident was covered up at the time by the UK government, as Prime Minister Harold Macmillan feared that it would harm British nuclear relations with America, and so original reports on the disaster and its health impacts were ...

Between March and July 1962, a radiation incident in Mexico City occurred when a ten-year-old boy took home an industrial radiography source that was not contained in its proper shielding. Five individuals received significant doses of radiation from the 200-gigabecquerel cobalt-60 capsule, [1] four of whom died. [2]
It was the worst civilian nuclear radiation accident in Japan prior to Fukushima (2011). [10] The incident exposed the surrounding population to hazardous radiation after the uranium mixture reached criticality. Two of the three technicians mixing fuel were killed.
