Abstract:
Objective To summarize and statistically analyze the automatic monitoring data of environmental gamma dose rates in Beijing, 2020-2024, identify the main influencing factors of the monitoring data, and inform management decisions and public services. Methods A statistical analysis was performed using data collected from national automatic radiation environment monitoring stations. Results For five environmental monitoring stations, the annual mean gamma dose rates from 2020 to 2024 ranged from 60.9 to 90.3 nGy/h. The overall annual mean was 71.4 nGy/h, with a standard deviation of 11.3 nGy/h. All values were within the range of statistical fluctuations of the local natural background radiation. The gamma dose rates of monitoring stations followed the order of E > A > D > B > C. Conclusion The gamma radiation levels at all monitoring stations were stable, and the monitoring results were closely related to their surrounding environments.
