If an exposure device is stolen, what should be the operator's first action?

When an exposure device is stolen, the operator's first action should be to notify the Radiation Safety Officer (RSO) or Radiation Protection Officer (RPO) as it is critical to ensure that the proper response protocols are initiated immediately. The RSO/RPO is responsible for overseeing safety measures associated with radiation hazards and has the authority and expertise to address emergencies related to radioactive material.

Prompt notification enables them to assess the situation, implement necessary security measures, and coordinate with law enforcement or regulatory agencies if needed. This action prioritizes safety and compliance with regulations, ensuring that the situation is managed by trained professionals who can mitigate potential risks associated with the theft of radioactive materials.

Other actions like investigating the theft or checking security cameras may seem sensible but should come after ensuring that the appropriate safety protocols and notifications have been made. Resuming regular duties in such a critical situation would disregard the potential hazards involved and could lead to serious repercussions.
