Multicomponent X-ray Shielding Using Sulfated Cerium Oxide and Bismuth Halide Composites.

ABSTRACT: Lead is the most widely used X-ray-shielding material, but it is heavy (density ≈ 11.34 g/cm³) and toxic. Therefore, the replacement of Pb with lightweight, ecofriendly materials would be beneficial, and such materials would have applications in medicine, electronics, and aerospace engineering. However, the shielding ability of Pb-free materials is significantly lower than that of Pb itself. To maximize the radiation attenuation of non-Pb-based shielding materials, a high-attenuation cross-section, normal to the incoming X-ray direction, must be achieved. In this study, we developed efficient X-ray-shielding materials composed of sulfated cerium oxide (S-CeO₂) and bismuth halides. Crucially, the materials are lightweight and mechanically flexible because of the absenc
