Gonadal shielding may reduce exposure to male gonads by up to what percentage?

• A. 10%
• B. 95%
• C. 75%
• D. 50%

Answer: (B)

Gonadal shielding is meant to protect the reproductive organs by blocking scatter radiation during imaging. When a properly placed shield is used for male patients, especially in pelvic or abdominal exams, the dose to the testes can be reduced very substantially—up to about 95% in ideal conditions. This large reduction comes from the shield intercepting photons that would otherwise reach the gonads, particularly scatter photons produced as X-rays pass through the body. The exact amount of reduction depends on how well the shield is positioned, the field size, and the imaging geometry; if the shield is misaligned or the beam geometry doesn’t favor the shield, the benefit will be less. So the maximum reliable figure you should recall is about a 95% reduction, recognizing that real-world results may vary.
