Which measures reduce staff exposure to scatter radiation during radiographic procedures?

• A. Stand farther from the source
• B. Wear protective apparel
• C. Use shielding devices
• D. All of the above

Answer: (D)

Reducing staff exposure to scatter radiation relies on three practical measures that work together: increasing distance from the x-ray source, wearing protective apparel, and using shielding devices. Standing farther away from the source significantly lowers dose because radiation intensity drops sharply with distance. Protective apparel—lead aprons and thyroid shields—attenuates scatter, with effectiveness determined by the lead equivalent of the gear. Shielding devices, such as portable barriers or fixed shields, intercept scatter before it can reach you.

Using all these together gives the greatest overall reduction in exposure, since distance lowers the amount reaching you, protective clothing blocks what would reach you, and shields provide a physical barrier between you and the scatter field.
