The operator should stand behind a wall or barrier when taking x-rays on a patient.

• A. True
• B. False
• C. Not sure
• D. Sometimes

Answer: (A)

Protecting the operator hinges on shielding and distance. When an x-ray is taken, the patient is in the beam, but some radiation scatters off the patient and surrounding tissues. Standing behind a wall or other lead-shield barrier places the operator in the path of far fewer photons, because the barrier attenuates the scattered radiation. This setup keeps you out of the direct beam and at a safer location, aligning with the ALARA principle to minimize occupational exposure. If a barrier isn’t available, maximize distance and use any portable shields while adhering to safety guidelines.
