Abstract Objective To discuss calculation method of radiation protection of radiography room from industrial X-ray, provide scientific basis for control of occupational exposure, and accumulate experience of shielding radiation.Methods Based on the method given by occupational health standard GBZ/T 250, the shielding design of a radiography room was optimized.Results According to the calculation in this paper, the shielding designs of the wall, the roof, and the radiation-shielded door of the radiography room all could be improved.Conclusion Based on GBZ/T 250, the optimization of shielding design of radiography room could be realized.
