Which action reduces exposure to radiological hazards for a responder?

• A. Build a resistance from the radiation source.
• B. Limit the time spent in a radiation hazard area.
• C. Wet their clothing first.
• D. Wear an oxygen mask.

Answer: (B)

The key idea is that radiation dose builds up with the amount of time you spend near the source. The faster you limit your time in the hazard area, the less total dose you receive. While increasing distance and using shielding also help, the option that directly lowers exposure in this set is spending less time in the area. Building resistance to radiation isn’t possible, wetting clothing doesn’t reduce the radiation dose, and an oxygen mask doesn’t protect against ionizing radiation.
