Optimal Design and Preparation of Novel Radiation Shielding Materials Used for Low Energy γ/X-Ray

The radiation shielding abilities of functional particles (Sm2O3, Er2O3, WO3 and Bi2O3) were simulated and proved to have a stronger absorption region and a weaker absorption region respectively. Four kinds of functional particles/epoxy radiation shielding composites used for low energy ��/X-ray were designed based on the edge absorption and synergistic absorption. By optimizing the proportion of functional particles in epoxy composites, the radiation shielding abilities bad been further improved. According to the results of optimal design, a kind of Sm2O3/Er2O3/WO3/Bi2O3/Epoxy composite was prepared and proved to be very efficient to shield low energy ��/X radiation. ?
