Lead aprons used in fluoroscopy must be at least:

• A. 0.5-mm Lead
• B. 0.25-mm Lead
• C. 0.25-mm Lead Equivalent
• D. 0.1-mm Lead

Answer: (A)

Shielding effectiveness is described by lead equivalent thickness. For fluoroscopy, the protective apron should provide enough attenuation to guard against scatter from the procedure. A thickness of 0.5 mm of lead (0.5 mm Pb equivalent) is the minimum recommended to achieve meaningful protection for the wearer. Thinner options, like 0.25 mm lead or 0.1 mm, offer much less attenuation and expose the operator to more radiation, especially in interventional settings with significant scatter. So the standard minimum is 0.5 mm lead equivalent, making that choice the best one.
