| Abstract: | 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. |
