What lead thickness is required for bucky slot covers on fluoroscopy systems?

• A. 0.15 mm Pb
• B. 0.25 mm Pb
• C. 0.50 mm Pb
• D. 0.35 mm Pb

Answer: (B)

Scatter control around fluoroscopy equipment is essential for protecting staff. Bucky slot covers intercept scatter and leakage that can escape from the patient area as the beam is used. The shield thickness chosen for these covers must balance effective attenuation with practicality like weight and cost. The standard choice is 0.25 mm lead equivalent because it provides adequate attenuation of scatter at typical fluoroscopy energies (the beams used are usually in the higher kVp range, with scatter having lower effective energy) while keeping the shield reasonably light and affordable. Thinner options would not reliably reduce exposure to acceptable levels, and thicker shields, while offering more attenuation, add unnecessary weight and cost for this application. So, 0.25 mm Pb is the appropriate and commonly adopted thickness for bucky slot covers.
