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.
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 ...
The accident was attributed to a zirconium fragment that obstructed a flow-guide in the sodium cooling system. Two of the 105 fuel assemblies melted during the accident, but no contamination was recorded outside the containment vessel.

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 ]
Globally, there have been at least 99 (civilian and military) recorded nuclear reactor accidents from 1952 to 2009 (defined as incidents that either resulted in the loss of human life or more than US$50,000 of property damage, the amount the US federal government uses to define major energy accidents that must be reported), totaling US$20.5 billion in property damages.

[There were no deaths due to deterministic effects (i.e., people receiving a high dose of radiation, rapidly becoming ill, and dying); the 100–240 figure is an estimate of the number of people who died later in life due to cancer caused by radiation from the accident [29]]. 95–4,000+ [30] [31] 26 April 1986 Chernobyl disaster.
