Seashell as Radiation Shielding Material

About the Project

This study investigates the potential of seashell waste as an alternative sustainable material for radiation shielding applications. Seashells, which contain high concentrations of calcium carbonate (CaCO₃), will be processed into fine powders and incorporated into a suitable binding matrix to fabricate shielding samples with different compositions. The physical, structural, and morphological properties will be characterized using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). Radiation attenuation performance will be evaluated using selected radioactive sources. The linear attenuation coefficient and half-value layer will be determined to assess shielding effectiveness and potential applications in radiation protection.
