Novel ceramic tile/lead oxide nanocomposites were designed and assembled based on doping standard ceramic tiles with lead oxide nanoparticles to serve as promising alternative candidates for γ-ray shielding. Various techniques were used to examine the structural properties of the newly formed lead oxide nanoparticles-doped ceramic tile composites. The main parameter tested in order to characterize the mechanical properties of the newly formed nanocomposites was the modulus of rupture. Since the doping material used in this study was lead oxide nanoparticles, it was found that as its content increased in the ceramic body from 0.0 to 10.0 wt%, the modulus of rupture increased from 1.753 ± 0.07 to 2.674 ± 0.11 MPa, respectively. The curvature of the tiles’ edges, the percentage of water adsorption, and their bulk density were among the physical properties examined. The mass attenuation coefficients of the tested samples were evaluated at different γ-ray photon energies (from 59.53 to 1332.50 keV), in terms of the weight percentage of lead oxide nanoparticles. To confirm the γ-rays shielding capabilities of assembled nanocomposites, other shielding parameters were computed, including the mean free path, the effective atomic number, the half value layer, and the effective electron density. It was found that the ceramic tile containing 10.0 wt% lead oxide nanoparticles had the highest value of mass attenuation coefficient, effective atomic number, and effective electron density and the smallest value of half value layer and mean free path, with respect to all studied nanocomposites. This results proved that as the lead oxide nanoparticles content of ceramic-tile nanocomposites increased (from 0.0 to 10.0 wt%), so did their γ-ray shielding ability. Finally, it can be concluded that ceramic tile-loaded-lead oxide nanoparticles exhibited significant improvements in the γ-rays shielding parameters compared to that filled with bulk lead oxide under the same weight percentage.

新型瓷砖/氧化铅纳米复合材料的设计和组装基于用氧化铅纳米粒子掺杂标准瓷砖，作为γ射线屏蔽的有希望的替代候选物。使用各种技术来检查新形成的氧化铅纳米颗粒掺杂瓷砖复合材料的结构特性。为了表征新形成的纳米复合材料的机械性能而测试的主要参数是断裂模量。由于本研究中使用的掺杂材料是氧化铅纳米颗粒，发现随着其在陶瓷体中的含量从 0.0 wt% 增加到 10.0 wt%，断裂模量分别从 1.753 ± 0.07 增加到 2.674 ± 0.11 MPa。瓷砖边缘的曲率，吸水率，并且它们的堆积密度属于所检查的物理性质。根据氧化铅纳米颗粒的重量百分比，在不同的 γ 射线光子能量（从 59.53 到 1332.50 keV）下评估测试样品的质量衰减系数。为了确认组装纳米复合材料的 γ 射线屏蔽能力，计算了其他屏蔽参数，包括平均自由程、有效原子序数、半值层和有效电子密度。结果表明，在所有研究的纳米复合材料中，含有 10.0 wt% 氧化铅纳米颗粒的瓷砖具有最高的质量衰减系数、有效原子序数和有效电子密度，以及最低的半值层和平均自由程值。 . 该结果证明，随着瓷砖纳米复合材料中氧化铅纳米颗粒含量的增加（从 0.0 到 10.0 wt%），它们的 γ 射线屏蔽能力也随之增加。最后，可以得出结论，与填充有相同重量百分比的块状氧化铅的纳米颗粒相比，陶瓷砖负载的氧化铅纳米颗粒在 γ 射线屏蔽参数方面表现出显着改善。
