The main task for the nuclear shielding design is combining combined barrier against γ Gray and neutron. This paper offers an elaborate description of the types and performances of the currently applied γ Gray and neutron shielding material, and furthermore, roughly discusses the respective principal problems of these materials. The key problem that needs to be settled is the conflict between shielding effectiveness and other performances such as mechanical performance, heat-resistant stable anti-radiation property. At last the review sketches out the prospect of the γ Gray and neutron combined shielding materials, suggesting that the development of structure/function integrated radiation shielding materials is one of the future trends. It is noted that the application of rare earth materials in radiation protection should be the focus of further research.
