What type of incident would require an evaluation by the regulatory body?

An evaluation by the regulatory body is necessitated in the event of any significant radiation leak or accident involving a nuclear gauge because such incidents pose a direct threat to public health and safety, as well as the environment. These types of occurrences typically involve the release of radioactive materials, which can have serious consequences if not addressed swiftly and effectively. The regulatory body must assess the situation to determine the extent of the radiation leak, evaluate potential exposure risks, and implement necessary remedial actions.

In contrast, minor equipment malfunctions typically do not have immediate implications for safety, and they may not require the same level of scrutiny or intervention as significant incidents. Scheduled equipment inspections and annual safety audits are routine measures intended to ensure compliance and function without the urgency associated with a radiation leak or accident.
