Abstract Objective To know the evaluation situation and existing problem of occupational disease hazard radiation protection evaluation of nuclear medical treatment project in Hebei province, and put forward some feasible suggestions. Method To collect relevant information and official reports on the occupational hazard radiation protection evaluation in 32 nuclear medical construction projects commissioned from 2011 to 2018, mainly from the general situation of project, site selection and surrounding situation, layout process and radioactive waste management, and put forward feasible opinions and suggestions. Results Among the 32 nuclear medicine construction projects, 23 were pre-evaluated and 9 were evaluated for the control effect. Nuclear medicine construction projects are mainly concentrated on tertiary hospitals, with 13 (72.33%), followed by 3 private hospitals (16.67%). Five (15.6%) of the projects were not properly located. It is suggested that project units should strengthen shielding protection and strengthen the management of radioactive waste and patients after drug administration. In the layout flow chart of the initial submission, it was found that there were 79 problems such as the intersection of medical, patient and nuclide routes, the lack of functional rooms, and the confusion in the division of the three zones. After the radiation protection evaluation, the number of related problems was reduced to 18. Among them, the division of the three zones and the intersection of internal routes have been resolved. Some problems in the management of gaseous radioactive waste in the initial data of the project have been well solved after radiation protection evaluation. Conclusion Radiation protection assessment of occupational disease hazards in construction projects is an important measure for nuclear medical construction projects to control radioactive pollution and protect personnel and environment safety at the source, which needs to be paid great attention by the construction units and relevant administrative departments.
