If your direct reading dosimeter goes off scale while operating an exposure device, what is your next step?

When a direct reading dosimeter goes off scale while operating an exposure device, the appropriate response is to stop work and contact your Radiation Safety Officer (RSO) or Radiation Protection Officer (RPO). This course of action is critical because an off-scale reading indicates exposure levels that could be dangerously high. Continuing to work could lead to potential overexposure to radiation, which poses serious health risks.

Notifying the RSO or RPO is essential as they have the training and authority to assess the situation and determine the necessary safety measures or actions needed to protect personnel and maintain safe operating conditions. They can provide guidance on how to proceed and ensure that the exposure device operation complies with safety protocols and regulatory requirements.

Other options, such as continuing to work carefully or adjusting the dosimeter's settings, could lead to significant risks and are not advisable under circumstances where there is potential for high radiation exposure. Notifying only another team member does not adequately address the immediate risks and does not involve the appointed safety authority who can manage the situation effectively.
