Isophthalic polyester resin was reinforced by using different metal oxides (lead(II)oxide, tungsten(VI)oxide and ferric oxide) and different reinforcement ratios (10–50%). Ionizing electromagnetic radiation shielding performance of the composites were determined by gamma spectrometric techniques for three different ionizing electromagnetic radiation (IEMR) energy regions (60–392, 662–898, 1173–1836 keV). Density evaluation, FTIR analysis, SEM studies were carried out. The IEMR attenuation performances of the composites were determined with gamma spectroscopy and found to be satisfying. These composites give better performance with respect to reference lead, especially in the case of the applications that weight of IEMR shield is important.

制备、表征和比较电离电磁辐射性能：第 I 部分——金属氧化物增强聚合物复合材料

通过使用不同的金属氧化物（氧化铅（II）、氧化钨（VI）和氧化铁）和不同的增强率（10-50%）来增强间苯二甲酸聚酯树脂。复合材料的电离电磁辐射屏蔽性能通过伽马光谱技术对三个不同的电离电磁辐射 (IEMR) 能量区域 (60-392、662-898、1173-1836 keV) 进行测定。进行了密度评价、FTIR分析、SEM研究。复合材料的 IEMR 衰减性能由伽马光谱确定，结果令人满意。这些复合材料相对于参考铅具有更好的性能，尤其是在 IEMR 屏蔽重量很重要的应用中。
