Wireless positioning and 5G transmission technologies provide opportunities for real-time monitoring of personal dosimetry and location in nuclear facilities.By employing Ultra-Wideband(UWB) positioning and 5G communication technology, a real-time monitoring system for personal dosimetry and location was developed.Targeting the application scenarios in nuclear power plant radiation-controlled areas, this study designed and implemented wireless positioning algorithms, data transmission and fusion methods, and developed wireless positioning and 5G communication modules, which were integrated with traditional electronic personal dosimeters.Test environments were established in both laboratory settings and nuclear power plant radiation-controlled areas to evaluate the positioning accuracy and real-time data transmission performance.The results demonstrated that the positioning accuracy reached 0.496 m in the laboratory and 0.463 m in the radiation-controlled area, meeting practical application requirements.The research findings confirm that the proposed system can leverage 5G private networks in nuclear power plants to achieve the real-time monitoring of personnel dosimetry and location information.
