What is the final step in the series of actions a radiographer should take if their camera is lost?

The final step a radiographer should take if their camera is lost is to call the Radiation Safety Officer (RSO). This action is critical because the RSO is responsible for ensuring compliance with safety regulations and managing incidents involving radiation sources. Notifying the RSO allows them to assess the situation, initiate appropriate emergency protocols, and help mitigate any potential risks related to the loss of the camera, such as contamination or exposure to the public.

Informing the RSO also ensures that proper documentation and investigation can be carried out, which are essential for understanding how the loss occurred and preventing future incidents. This step is part of professional responsibility in maintaining safety standards in environments that handle radiological materials.

Other options like leaving the area, asking for help, or sending an email do not provide the same level of immediate action and accountability as contacting the RSO directly. These actions could be part of the process, but they do not address the critical need for formal reporting and management of the radiological hazard posed by a lost camera.
