Radiology · Radiation safety and radiobiology: leaded eyewear for lens protection
Sample itemCataract is the radiation tissue reaction of main concern to interventional operators. Which item most directly reduces this risk?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
B. Leaded eyewear
The lens is among the most radiosensitive tissues in the head and is not covered by an apron or collar. Wrap-around leaded glasses cut scatter reaching the eyes, and ceiling-mounted shields add protection.
Option by option
A. Lead gloves
Lead gloves reduce dose to the hands but not to the lens.
B. Leaded eyewear (correct)
Correct. Leaded glasses shield the lens that other garments leave exposed.
C. Lead apron with higher equivalence
A heavier apron covers the trunk and does not protect the eyes.
D. Thyroid collar
A thyroid collar protects the thyroid and not the eyes.
