What is the proper response if a survey instrument alarms during a contamination survey?

In the context of radiological safety, if a survey instrument alarms during a contamination survey, the proper response is to stop work and notify Radiological Control personnel. This is critical for maintaining safety protocols and ensuring that any potential hazards are assessed and handled by trained professionals.

The alarm indicates the presence of contamination or radiation levels that exceed safe limits, which could pose risks to personnel. By halting work immediately, personnel can prevent further exposure or contamination and allow experts to evaluate the situation. Notifying Radiological Control personnel is essential because they possess the expertise to determine the appropriate follow-up actions, including decontamination or further investigation of the alarm's cause.

Other responses, such as continuing to work despite the alarm or merely checking the instrument settings, could lead to unsafe conditions and potentially endanger health and safety. Moving to a safe location might seem prudent, but without immediate action to address the alarm, individuals may still be exposed to hazards that require prompt attention. This emphasizes the need for a coordinated response in radiological surveys to prioritize safety.
