Which action requires moving people to a safer location during a radiological incident?

• A. Evacuation
• B. Isolation
• C. Clearance
• D. Triaging

Answer: (A)

Evacuation is moving people away from the radiation source, plume, or contaminated area to a location with lower exposure. This protective action directly reduces radiation dose by relocating individuals to safer surroundings and helps prevent both external exposure and potential internal contamination. Isolation would keep people out of or from entering a contaminated area to limit spread, not necessarily relocate them to safety. Clearance is about determining when an area can be reoccupied after decontamination or when restrictions can be lifted. Triaging focuses on prioritizing medical care for casualties, not relocation. So when the goal is to move people to a safer location, evacuation is the action that fits.
