Which shielding device is worn when the lower jaw or larynx is X-rayed?

• A. Thyroid shield
• B. Eye shields
• C. Lead gloves
• D. Lead apron

Answer: (B)

Radiation protection focuses on shielding organs that are most sensitive to ionizing radiation in the area being imaged. When the lower jaw or larynx is X-rayed, the eyes lie close to the field and the lenses are highly radiosensitive, so shielding the eyes with leaded eyewear helps reduce the dose to the lenses and lowers the risk of radiation-induced cataracts.

Other shields protect different areas (a thyroid shield guards the neck’s thyroid, a lead apron protects the torso, and lead gloves protect the hands), but for this head and neck exposure, eye protection addresses the particular risk most directly.
