Study on the radiation shielding for room of industrial X-ray radiography

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. (authors)
