Which shielding device is worn when the skull is X-rayed?

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

Answer: (A)

In radiography, protecting radiosensitive tissues from scatter radiation is essential. The thyroid gland, located in the neck just under the jaw, is particularly vulnerable and lies near the skull imaging field. A thyroid shield is worn to intercept scatter radiation reaching the thyroid during skull X-rays, reducing the gland’s radiation dose without interfering with the diagnostic image. Lead aprons protect the torso, eye shields protect the lenses, and lead gloves protect the hands, but none of those are specifically used for shielding during a skull exam.
