If a gauge is missing from the back of a truck upon return to the office, what should you do immediately?

Contacting the Radiation Safety Officer (RSO) and the regulatory agency is the appropriate immediate action if a gauge is missing. This step ensures that the situation is addressed according to established safety protocols and regulatory requirements.

The RSO is trained to handle incidents involving radiation safety, and their involvement is crucial in determining the best course of action. Additionally, notifying the regulatory agency is often a legal requirement when it comes to the loss of radiation sources. They can provide guidance and support in locating the gauge and managing any potential risks associated with its absence.

Prompt reporting is essential in such situations to ensure the safety of personnel and the public, maintain compliance with regulations, and facilitate a thorough and effective response to the loss.
