Which type of examination is specifically noted for requiring additional protection for the gonads?

Pelvic x-rays are specifically noted for requiring additional protection for the gonads due to the anatomical location and the potential exposure to reproductive organs. During a pelvic x-ray, the lower abdominal region is imaged, which is close to the gonads in both males and females. The use of protection, such as lead aprons or gonadal shields, is critical during these procedures to minimize radiation exposure and protect sensitive tissues that can be affected by ionizing radiation.

In contrast, chest x-rays primarily focus on the thoracic cavity and do not pose a significant risk to the gonads. Dental x-rays involve imaging the mouth and surrounding areas and typically do not require specific gonadal protection since the area of interest is far removed from the reproductive organs. Similarly, hand x-rays focus on the extremities and are unlikely to result in any meaningful exposure to the gonads, thus reducing the urgency for protective measures.
