What action should be taken if radiation levels exceed acceptable limits during a survey?

When radiation levels exceed acceptable limits during a survey, it is crucial to immediately notify your supervisor and secure the area. This action ensures that safety protocols are followed and minimizes the risk of exposure to individuals who may be in the vicinity. Securing the area prevents unauthorized access to a potentially hazardous environment, thus protecting not only the personnel involved in the radiography but also others who might be affected.

This procedure is a fundamental safety measure in radiation protection practices. It allows supervisors to initiate appropriate responses, which may include evacuating personnel, implementing corrective actions, or assessing the cause of the radiation spike. Therefore, the prompt reporting and securing of the area are critical in managing potential radiation exposure incidents effectively and maintaining a safe working environment.

Other options, such as increasing exposure time, reducing the number of surveys, or continuing work with increased caution, do not prioritize safety in the same way. These options could potentially expose individuals to unnecessary risk, making immediate notification and area security the most responsible and effective course of action.
