Which statement is true about radiological alarms in the plant?

• A. They are decorative.
• B. They monitor only environmental outside the plant.
• C. They are used in the plant to monitor radiological conditions and sample air in the plant.
• D. They do not affect safety.

Answer: (C)

Radiological alarms are a part of the plant’s safety system that continuously monitor radiation levels and sample the air inside work areas. This setup provides early warning of elevated radiation or airborne radioactive contaminants, so workers can take protective actions quickly—like pausing operations, increasing ventilation, or evacuating if needed. That capability to monitor conditions and sample air inside the plant is why this statement is true. They are not decorative, they aren’t limited to outside monitoring, and they do affect safety by guiding timely responses.
