Abstract： In order to ensure the sufficient penetration ability, the highenergy Xrays generated by the accelerator device are often used to accurately measure the internal defects of depleted uranium materials. High energy photons produce neutrons when they collide with the matter with high atomic number. Neutrons have highly destructive radiobiological effects. The shielding mode of neutron ray is also significantly different from that of Xray. Considering the safety of radiographic testing, it is necessary to study the properties of neutrons produced in activation of depleted uranium materials by highenergy Xrays. Through theoretical analysis and mathematical model establishment, the lower energy limit of neutrons generated in the interaction between Xrays with different energy and depleted uranium alloy was investigated. The study could provide safety guidance for the selection of upper energy limit of ray source in product internal defect detection.
