PREPARATION OF RESIN NANO-CERIUM SHIELDING RADIATION COMPOSITE AND ITS PROPERTIES RESEARCHING

An Jun, Liu Jihua, Xin Yinchang (College of Chemistry, Chemical Engineering and Material Science, Shan Dong Normal University, Jinan 250014, China)  
Resin nano-cerium composite was prepared with a styrene sulfonic acid sodium cation exchange resin, which was used to shield middle and low energy X-ray radiation. The transmission electroscope test results showed that the nano-cerium was evenly distributed in the composite and its diameter was about 20 nm. The attenuation to X-ray was measured by X-ray CT scanning machine. It was found that the property of attenuation to X-ray of nano-cerium was much better than that of typic cerium nitrate.Otherwise, it was a multinomial properties shielding radiation composite, which could be used as intensifying screen because of its small size affect and special tracks.
