International Nuclear Event Scale
scale to enable communication of safety information in nuclear accidents / From Wikipedia, the free encyclopedia
The International Nuclear Event Scale (INES) is a system introduced by the International Atomic Energy Agency (IAEA). It was introduced to allow people to communicate how serious a nuclear accident is. Other people are then able to react faster to take protection measures. For each level, there is a list of things that must be there, for the accident to be of that level.
There are 7 levels on the INES scale:
7
Major accident
(maximum credible accident)
