| Abstract: | EGS4 code, a general known Monte Carlo computer simulation package, is introduced in this paper. The application of EGS4 to simulate the radiation dose distribution of the accelerator shielding system for a large object radiation inspecting system(LORIS) is described in the paper. The results obtained by EGS4 are compared with the experiment.Explanation of exceptional dose distribution is given. A new design feature is presented. |
