In a robust QA program, which activity specifically assesses the integrity of protective barriers?

• A. Shielding integrity assessments.
• B. Patient comfort surveys.
• C. Annual software license audits.
• D. Room color matching.

Answer: (A)

Shielding integrity assessments verify that protective barriers continue to attenuate X-ray exposure as designed, which directly safeguards staff and patients. This activity focuses on the barrier itself—checking walls, doors, leaded glass, and any shielding components for cracks, gaps, wear, or improper installation. It also involves measuring transmitted radiation with calibrated instruments at designated locations to confirm that the barrier’s lead equivalence and attenuation meet the required specs and regulatory limits. Regular shielding checks ensure that the barrier remains effective after construction, renovations, or changes in room usage.

Other options don’t address the barrier’s protective function. Patient comfort surveys gauge the patient experience, not radiation protection. Annual software license audits relate to IT systems, not physical shielding. Room color matching has no impact on shielding or radiation safety.
