Name the typical PPE used to limit external exposure and contamination in radiology.

• A. Lead aprons and thyroid shields, lead gloves, lead glasses, shoe covers; sometimes dosimeter collars.
• B. Leather gloves and safety goggles; protective hat.
• C. Fire-resistant lab coat and PPE; no shielding required.
• D. Cotton clothing with no shielding.

Answer: (A)

In radiology, protecting workers from radiation relies on shielding between the source and the wearer, with lead-based gear providing the most effective attenuation of X-rays. The typical equipment used to limit external exposure and prevent contamination includes a lead apron to protect the torso, a thyroid shield for the neck, lead gloves for the hands during close-proximity tasks, leaded glasses to reduce eye lens dose, and shoe covers to help maintain cleanliness and limit spread of contamination. Sometimes a dosimeter collar is worn to monitor exposure to the thyroid area. Other options lack the necessary shielding (for example, leather gloves, ordinary safety goggles, or cotton clothing) and do not provide meaningful protection against ionizing radiation.
