In Japan, people wear personal radiation dosimeters to enter radiation controlled areas for occupational radiation exposure management. The cumulative value for one month is the occupational radiation exposure dose value. Managers want to make appropriate announcements to medical staff with high occupational radiation exposure doses to make them awareness of radiation protection, but it is difficult to do so based on occupational radiation exposure doses alone. In this study, we developed an occupational exposure information system that collects and analyzes sensor information and DICOM (Digital Imaging and Communications in Medicine) data to know the situations (location, time, etc.) at that time. In the trial use of the system, it was possible to know the situations (location, time, etc.) at that time.
