What is the appropriate response to a Continuous Air Monitor (CAM) alarm?

The appropriate response to a Continuous Air Monitor (CAM) alarm involves a series of critical steps that prioritize safety and effective communication in a potentially hazardous radiation situation. Noticing an alarm from a CAM indicates an elevated level of airborne radioactive materials, which requires immediate action.

The correct response to stop work, warn others, exit the area, and notify Radiation Control (Rad Con) emphasizes a proactive approach to managing potential exposure to radiation. Stopping work ensures that no further activity occurs that could increase the risk of inhalation or contact with radioactive materials. Warning others is vital for ensuring that all personnel are aware of the potential hazard, allowing them to take necessary precautions and protect themselves. Exiting the area minimizes the risk of exposure to elevated radiation levels, while notifying Rad Con allows trained professionals to assess the situation and implement safety measures.

In contrast, options like evacuating the site or assuming the alarm is merely due to natural background radiation are not appropriate initial responses as they do not ensure the safety of personnel in the immediate vicinity or acknowledge the seriousness of the alarm. These alternatives can lead to increased risk for those still present in the area, as they fail to address the potential danger effectively.
