Objective:To develop a simulation program by the name of“Shielding Calculation Software of Medical electron accelerator Treating room”, which based on the common model of radiation protection shielding calculation. We can use this program to estimate the thickness of shield when Medical electron accelerator is work on the Electron model and X-ray model, avoiding onerous work and error by handwork calculation. Methods:Considering the available radiation protection shielding calculation experience, and analyzing the hazard factor to staff and public, when we finish the program, we may contrast the simulation results with the actual shielding results. Results:The simulation program was completed, and the simulation results were carried out by this program. By considering the actual shielding effect, we find that the simulation results are very close to the results based on the empirical formulation. Conclusion:This computer method is very convenient to estimate the thickness of shield, and the simulation results are credible.
