Abstract IIn this paper, starting from the research status and requirements of γ-ray protection materials, nuclear radiation protection materials containing MWCNTs and lead was prepared, and its mechanical properties and radiation protection properties were tested.Use high-dose rate gamma radiation to shear the carbon nanotubes to make them functional, and use the mechanical blending method as the main processing method to prepare the lead-containing EVA polymer resin radiation protection sheet containing chopped carbon nanotubes. Based on the principle of radiation cross-linking of polymer compounds, the composite material is modified by radiation cross-linking using a high-energy electron beam accelerator, the mechanical properties of the finished product are characterized by tensile testing, and the shielding performance of the finished product is tes-ted through radiation shielding experiments,verify and discuss the modification principle and radiation shielding mechanism of short-cut carbon nanotubes added to the sheet. The prepared gamma-ray radiation protection material has light weight, flexibility, environmental protection and high quality attenuation characteristics for gamma rays, which can well meet the protection effect and the application background of light weight and portability. It is a reference for the design of flexible radiation protection materials.
