Protective aprons should be inspected annually for which condition?

• A. Lead integrity
• B. Presence of cracks
• C. Fiber tears
• D. Discoloration

Answer: (B)

Shielding integrity is essential for dental radiography. Protective aprons must stay continuous so they can effectively attenuate scatter radiation. The most important defect to identify during a routine annual check is the presence of cracks in the lead shielding. Hairline cracks or splits break the barrier and create paths where radiation can pass through, reducing protection even if the apron looks fine overall. That direct connection between a crack and reduced shielding is why this is the primary condition to inspect for.

Discoloration or fabric tears might indicate wear, but they do not necessarily reveal a loss of shielding. A general check of lead integrity sounds sensible, but it’s the cracks that most precisely indicate compromised protection, which is why the annual inspection focuses on detecting any cracks and removing the apron from service if found.
