Radiation protection in radiology is important because radiation may cause harm to the human body. The equipment for radiation protection is essential to ensure safe operations. Currently, there is widespread research on lead-free radiation shielding material. The aim of this research was to study lead-free material containing epoxy and iodine contrast media that was easy to form, low in cost, and environmentally friendly. The results showed that 2-cm material thickness with a concentration of 20% iodine had the greatest properties of radiation attenuate in the peak potential applied at technique 60-120 kVp, but the structure and strength of the shielding materials were decreased in accordance with increasing concentrations of iodine contrast media. It can be concluded that the lead-free epoxy radiation-shielding materials are able to absorb radiation at energy levels of 60-120 kVp. However, with improvement on homogeneity in the future, it could be used as a refractory shielding material in the radiology department.
放射学中的辐射防护很重要，因为辐射可能会对人体造成伤害。辐射防护设备对于确保安全操作至关重要。目前，关于无铅辐射屏蔽材料的研究广泛开展。本研究的目的是研究含环氧树脂和碘造影剂的无铅材料，该材料易于成型、成本低且环保。结果表明，在60 - 120 kVp的技术峰值电位下，厚度为2厘米、碘浓度为20%的材料具有最大的辐射衰减性能，但屏蔽材料的结构和强度会随着碘造影剂浓度的增加而降低。可以得出结论，无铅环氧辐射屏蔽材料能够吸收60 - 120 kVp能量水平的辐射。然而，随着未来均匀性的改善，它可作为放射科的耐火屏蔽材料使用。
