Which set of steps is used to reduce radiation exposure to patients and personnel?

• A. Beam Restriction, Shielding, High kV, Low mA
• B. High kV and Low mA
• C. Beam Restriction Only
• D. Shielding Only

Answer: (A)

The main idea is to minimize exposure by combining several protective and optimization steps. Restricting the X-ray beam to the area of interest lowers patient dose and reduces scatter, while shielding protects radiosensitive tissues from stray exposure. Using higher kVp with lower mA decreases the overall dose required to achieve sufficient receptor exposure, without sacrificing image quality when balanced correctly. When these methods are used together—beam restriction, shielding, and optimized technique (high kVp with low mA)—exposure to both patients and personnel is reduced more effectively than any single measure alone. The other approaches rely on only one or two strategies, which either don’t sufficiently limit exposure or risk compromising image quality.
