Abstract

With the advancement in diagnostic imaging, providing shielding against X-rays has become a significant concern. While Lead has been extensively used as the shielding material, it is costly and toxic to humans and the surrounding environment. This study aims to evaluate the feasibility of eggshells as alternative shielding material against diagnostic X-rays. To this end, the eggshells were collected, ground, sieved and mixed with cement and water with an increasing amount. Radiographic analysis was utilized to measure the performance of the shields. The results showed that increasing the number of eggshells increased its shielding performance; however, more shielding is required at higher X-ray energies. Nevertheless, the performance of the standard Lead shield and the shield with the highest number of eggshells yielded a comparable result. The eggshells can be used as alternative shielding material against diagnostic X-rays.
