Therefore, effective alternatives to Pb shielding materials are needed to provide adequate radiation protection for radiosensitive organs while maintaining diagnostic accuracy and does not compromise clinical objectives of the examination. In pediatric patients, in particular, dose reduction to protect radiosensitive organs is of prim importance. Dose reduction has classically been a significant factor in diagnostic imaging. Because the restlessness or movement of young children during the examination may result in poor organ shielding and reduced diagnostic accuracy, repeat radiography may be needed, which increases the radiation dose, careful consideration of gonadal shielding is warranted. Pelvic radiography, which is one of the more frequent and high-dose examination for children, the radiosensitive organs in the lower abdomen, especially the gonads, is exposed to ionizing radiation. However, lead (Pb) is shown to obscure important anatomical structures during imaging and produce artifacts necessitating repeat radiology. Radiation using conventional X-ray is associated with exposure of radiosensitive organs and typically requires the use of lead for protection.
