What is the minimum lead equivalent required for a fluoroscopic protective curtain?

• A. 0.20 mm Pb eq
• B. 0.25 mm Pb eq
• C. 0.30 mm Pb eq
• D. 0.35 mm Pb eq

Answer: (B)

Protective curtains in fluoroscopy act as a secondary shield to intercept scattered radiation from the patient. The curtain must meet a minimum lead equivalent to ensure sufficient attenuation of those scattered photons before they reach staff. The standard minimum is 0.25 mm Pb eq. This value provides a good balance between effective protection and practicality, given the typical energies involved in fluoroscopy. Lower values would not meet safety guidelines, while higher values would offer more shielding but aren’t required for curtains in ordinary use. Thus, the minimum lead equivalent required for a fluoroscopic protective curtain is 0.25 mm Pb eq.
