Which protective action(s) are guided by PAGs during a radiological emergency?

• A. Evacuation
• B. Sheltering
• C. Decontamination
• D. All of the above

Answer: (D)

Protective Action Guides establish thresholds to trigger actions that reduce radiation dose to the public during a radiological emergency. They guide when to evacuate people from an area, when to shelter in place to minimize inhalation and external exposure, and when to decontaminate individuals or surfaces to remove radioactive material. The decision levels depend on the specific radionuclide, projected dose, timing, and weather, so actions may change as the situation evolves. Because PAGs cover evacuation, sheltering, and decontamination, all of these protective actions are guided by PAGs.
