Which item is typically used to avoid gonadal exposure to x-rays?

The use of a lead apron is essential in radiology for minimizing radiation exposure, particularly to sensitive areas like the gonads. Lead aprons are designed to absorb x-rays and prevent them from reaching the reproductive organs, which can be especially vulnerable to the harmful effects of radiation. This protective measure is important during diagnostic procedures that involve x-ray imaging, ensuring the safety and health of patients, particularly in scenarios involving children or individuals of childbearing age.

In contrast, safety glasses primarily protect the eyes from physical hazards or debris rather than radiation. A dental bib serves a different purpose by keeping patients dry and clean and does not provide any radiation protection. Adjustment tools may be used for equipment calibration or positioning during imaging but have no relation to protecting against radiation exposure. Thus, the lead apron stands out as the appropriate answer for reducing the risk of gonadal exposure during x-ray procedures.
