During which condition is it acceptable to operate a nuclear gauge without proper supervision?

Operating a nuclear gauge without proper supervision is never acceptable due to the inherent safety risks involved in handling radioactive materials. Proper supervision ensures that safety protocols are followed, minimizing the risk of accidents and ensuring that the operator can respond appropriately to any potential hazards. Supervised operations are particularly important in environments where strict regulatory compliance and safety measures must be maintained to protect both the operator and the public from exposure to radiation. Supervision by a qualified individual ensures that safety procedures are adhered to and that the operator has immediate access to guidance in case of an emergency.

While it may seem that experience or proximity to a certified colleague could mitigate risk, these factors do not substitute for the continuous oversight required for safe operation. Prior experience does not guarantee adherence to current safety protocols, and having a training session scheduled does not equate to being ready or certified to operate safely.
