Which barrier is designed to reduce leakage and scatter radiation to adjacent areas?

• A. Lead apron
• B. Primary protective barrier
• C. Bucky slot cover
• D. Secondary protective barrier

Answer: (D)

When shielding in radiography, the aim is to protect people and areas from radiation by using barriers that block the beam and barriers that reduce radiation that escapes to nearby spaces. The barrier designed to cut down leakage and scatter radiation reaching adjacent areas is the secondary protective barrier. It targets photons that escape from the tube housing (leakage) and photons produced by interactions in the patient or surroundings (scatter) so they don’t reach neighboring rooms or corridors. The lead apron is personal shielding worn by staff or patients, not an architectural barrier. The Bucky slot cover reduces leakage and scatter through the Bucky slot itself, but it isn’t the general barrier guarding adjacent areas. The primary protective barrier blocks the direct primary beam, not primarily leakage or scatter to other areas.
