If the operator cannot leave the room during an exposure, what is recommended?

• A. Stand behind a protective barrier
• B. Stay in the room without barrier
• C. Hold the exposure switch from the doorway
• D. Stand next to the patient

Answer: (A)

When protecting yourself from radiation, shielding and distance are key. If you can’t leave the room, the safest option is to stand behind a protective barrier. This lead-lined barrier absorbs scatter radiation, greatly reducing the dose you receive while the exposure is taking place.

Staying in the room without any barrier, holding the exposure switch from the doorway, or standing next to the patient would place you in the path of scatter or the primary beam, increasing your exposure and violating safe-practice guidelines. The goal is to maximize shielding and keep as much of your body behind it as possible, while the exposure is being completed.
