摘　　要：利用苯乙烯磺酸钠阳离子交换树脂制备树脂纳米硫酸钡 ,利用X 射线CT扫描装置精确测定物体的CT值 ,获得树脂纳米硫酸钡对X 射线高能量电磁波的吸收率并与普通硫酸钡的吸收率进行比较 ,研究树脂包复的纳米硫酸钡粒度与衰减X 射线能力的相依性 ,探索研究硫酸钡粒度大小对X 射线衰减的影响 ,为制备高性能强防辐射材料提供行之有效的方法及表征手段。The resin encapsulated nanometer barium sulfate was prepared w ith cation exchange resin-sodium styrene sulfonate. Its computed tomography ( CT) value was precisely determined by means of X-ray CT scanning device, the co mparison of obtained absorption rate of resin encapsulated nanometer barium sulf ate to high energy electromagnetic wave with ordinary barium sulfate was made so as to investigate the dependence of granularity of resin encapsulated nanometer barium sulfate on the attenuation ability and the effect of size of granule of barium sulfate on its X-ray attenuation ability to high energy electromagnetic wave. This paper provides an effective preparative and characteristic means for strong radiation protective material with high performance.
