Abstract Objective Using a sinking X-ray inspection room as a research object, monitoring the radiation dose rate level around the inspection room,the results were analyzed and evaluated in conjunction with relevant standards. To evaluate the advantages and disadvantages of the design of this type of inspection room, and to provide a scientific basis for strengthening the radiation safety supervision of this type of X-ray inspection room.Methods Using appropriate instruments to monitor the ambient dose equivalent rate of the environment around the inspection room, and to carry out theoretical estimation according to the shielding specifications, and to carry out evaluation based on actual measurement results and estimation results.Result The radiation dose rate around the interest points of the sinking type flaw detection room meets the requirements of relevant standards.Conclusion The environmental management of atypical X-ray inspection rooms should be strengthened to prevent the hidden radiation safety hazards.
