2007 ISO radioactivity danger symbol intended for IAEA Category 1, 2, and 3 sources defined as dangerous sources capable of causing death or serious injury.
This article lists notable civilian accidents involving radioactive materials or involving ionizing radiation from artificial sources such as x-ray tubes and particle accelerators. Accidents related to nuclear power that involve fissile materials are listed at List of civilian nuclear accidents. Military accidents are listed at List of military nuclear accidents.
Scope of this article
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.
- To qualify as "civilian", the operation/material must be principally for non-military purposes.
- The event is not an event involving fissile material or a nuclear reactor.
