| Abstract: | Despite its several benefits, cone-beam computed tomography (CBCT) has a significant drawback in terms of the exposure dose required for its diagnostic assessment. The theoretical calculations showed that the risks associated with using CBCT can be evaded by designing effective shielding. Polycarbonate/copper oxide nanocomposites (PC/CuO NCs) that contain carboxymethyl cellulose (CMC), polybutylene terephthalate (PBT) or polyethylene oxide (PEO) polymers, or polymethyl methacrylate (PMMA) polymer can be effective alternatives to the X-ray shielding materials which are based on toxic lead. The mass attenuation coefficient (MAC) and linear attenuation coefficient (LAC) were calculated for the PC/PMMA/CuO, PC/CMC/CuO, PC/PBT/CuO and PC/PEO/Cuo polymer NCs using the Phy-X/PSD program. The half value layer (HVL) and tenth value layer (TVL) were then calculated using the attenuation coefficients. Additionally, the mean free path (MFP) of the examined samples was calculated. To cover a wide range of energy that interacts with the investigated substances, all of these shielding characteristics were computed for the X-ray incidence energy range between 0.015 and 15 MeV. When compared to PC/PMMA/CuO, PC/PBT/CuO, and PC/PEO/CuO polymer NCs, the results showed that the PC/CMC/CuO polymer NCs had the superior X-ray shielding qualities. As a result, we came to the conclusion that the PC/CMC/CuO polymer NC would be a suitable candidate for X-ray shielding. [ABSTRACT FROM AUTHOR] |
