The Radiation Shielding Design Of X-Ray Velocimeter

In this paper, the basic principle of the velocity measurement of the intermediate ballistic velocimeter on X-ray is introduced. Based on the optimization principle of radiation protection for the limitation of the second category of limited equivalent (i.e., 0.1mSv per week for standard), it gives the structure of the radiation shielding of X ray velocimeter, and analysis and obtains. The design method and design formula of the thickness selection of the shielding structure. The experimental results show that the design method is reliable, and it has guiding significance to the related design work.
