INES (International Nuclear Event Scale)

The International Nuclear Event Scale (INES) is a tool used to communicate the severity of nuclear incidents and accidents. It categorizes events from Level 0 (deviation with no safety significance) to Level 7 (major accidents with widespread consequences). The scale helps ensure clear, consistent reporting worldwide, considering factors like radioactive releases, safety system failures, and impact on people and the environment. This standardized system aids regulators, operators, and the public in understanding the seriousness of nuclear events, supporting safety awareness and response planning.
