International Nuclear Events Scale

An international nuclear event scale is like a way to measure the severity of a nuclear accident. It was created by the International Atomic Energy Agency (IAEA) and starts from 0 (no safety significance) and goes up to 7 (major nuclear accident). Each number means a different level of seriousness; for example, a level 5 is an 'accident with wider consequences', which means that some people may have been exposed to radiation and there could be environmental damage. The scale is used to help people understand just how dangerous a nuclear event is, and it helps government officials and energy companies respond quickly to the situation.
