The International Nuclear Event Scale (INES) is a tool used to communicate the safety significance of nuclear and radiological events. It categorizes incidents on a scale from Level 1 (an anomaly) to Level 7 (a major accident), helping the public and authorities understand the potential impact of an event. Developed by the International Atomic Energy Agency (IAEA), the INES provides a standardized way to assess and report incidents. This scale aids in international communication and response, ensuring that information about nuclear safety is clear and consistent across different countries and organizations.
