Final answer:
Personnel wear lead aprons in the X-ray room during fluoroscopic examinations primarily to protect them from ionizing radiation.
Step-by-step explanation:
Personnel in the X-ray room wear lead aprons during fluoroscopic examinations to shield themselves from ionizing radiation emitted by the X-ray machine. Lead's effectiveness in absorbing and attenuating ionizing radiation makes it an essential protective material. The lead apron serves as a barrier, intercepting and reducing the dose of radiation reaching the wearer's body. This preventive measure is crucial to minimize the potential health risks associated with prolonged or repeated exposure to ionizing radiation. By providing a reliable shield, lead aprons contribute to the safety of medical personnel who routinely operate or assist in fluoroscopic procedures, ensuring their well-being and adherence to radiation safety practices.
