【摘要】 随着核工业和技术的快速发展，核安全受到日益广泛的关注，针对核辐射屏蔽材料的研究也越来越受到重视。相较于传统的屏蔽材料，高分子基辐射防护材料具有密度低、易成型等优点，成为目前科学研究的重点。本文首先介绍了X射线、γ射线和中子射线的特性和屏蔽机理，分别阐述了具有X射线、γ射线和中子防护功能的高分子基复合材料的研究进展，最后总结并展望了新型高分子基屏蔽材料的未来发展趋势。更多还原

【Abstract】 The study on nuclear radiation shielding materials has attracted more and more attention, as nuclear safty becomes a growing concern with the rapid development of nuclear industry and technology. Polymer-based shielding materials have been investigated due to the advantages of low density and easy molding which the traditional shielding materials lack. In this paper, the characteristics and radiation shielding mechanisms of X-ray, γ-ray and neutron were discussed. Then the latest research development of polymer-based composites for X-ray shielding, γ-ray shielding and neutron shielding were also reviewed. Finally, the future development of polymer-based materials for radiation shielding were prospected.更多还原
