Which action involves moving people away from danger during a nuclear/radiological incident?

• A. Evacuation
• B. Sheltering
• C. Vaccination
• D. Cleanup

Answer: (A)

Moving people away from danger is evacuation. In a nuclear or radiological incident, the fastest way to lower radiation dose for the population is to increase their distance from the source or contaminated area. Evacuation physically relocates people out of the affected zone, reducing inhalation and external exposure as the plume or contamination moves through or past the area. Sheltering, by contrast, keeps people in place but uses building shielding to lessen exposure, which is useful when evacuation isn’t feasible or safe right away. Vaccination doesn’t affect acute radiation exposure at all; it addresses disease protection rather than immediate radiological risk. Cleanup deals with decontamination after the incident and doesn’t protect people who are still in or near the danger zone. So the action that best describes moving people away from danger is evacuation.
