Abstract

This study focuses on synthesizing and characterizing Mg-doped SnO₂ nanoparticles as a safe substitute for lead-based X-ray shielding aprons. Various molar weight percentages of Mg dopant were utilized during synthesis, and the resulting samples were analyzed using multiple techniques, such as X-ray diffraction, UV–visible, Photoluminescence, Raman spectroscopy, energy-dispersive X-ray spectroscopy, high-resolution transmission and scanning electron microscopes. The nanoparticles were then combined with a nano-epoxy polymer composite and coated onto rexine cloth through drop casting. To assess the X-ray shielding performance, the percentage of attenuation, attenuation coefficient, and half-value layer studies were conducted. Comparative analysis with traditional lead oxide (PbO) aprons revealed that the 3% Mg-doped SnO₂ nanocomposite aprons exhibited superior X-ray attenuation properties. In summary, this study highlights the potential of Mg-doped SnO₂ nanoparticles as an effective, hydrophobic, and lightweight alternative to commercial aprons that are made of toxic, hydrophilic, and heavy lead-based materials.

系统研究掺镁二氧化锡环氧纳米复合材料围裙作为铅商用围裙替代品的潜在 X 射线衰减特性

本研究的重点是合成和表征掺镁二氧化锡纳米粒子，作为铅基 X 射线屏蔽围裙的安全替代品。在合成过程中使用了不同摩尔重量百分比的掺杂镁，并使用多种技术（如 X 射线衍射、紫外可见光、光致发光、拉曼光谱、能量色散 X 射线光谱、高分辨率透射电子显微镜和扫描电子显微镜）对所得样品进行了分析。然后，将纳米粒子与纳米环氧聚合物复合材料结合，通过滴注法涂覆到雷克辛布上。为了评估 X 射线屏蔽性能，进行了衰减百分比、衰减系数和半值层研究。与传统氧化铅（PbO）围裙的比较分析表明，掺杂 3% 镁的二氧化锡纳米复合材料围裙具有更优越的 X 射线衰减性能。总之，本研究强调了掺镁二氧化锡纳米粒子作为一种有效、疏水、轻质的替代品的潜力，可替代由有毒、亲水、重型铅基材料制成的商用围裙。
