A year-long investigation of air radon concentration at Beishan URL site and its surrounding areas was carried out using solid-state nuclear track detectors at 24 points,with quarterly sampling and measurements conducted. The results indicated that the annual radon concentration in the region ranged from 10 to 64 Bq·m-3,with a geometric mean (GM) of 27 Bq·m-3. The overall radon levels exhibited distinct seasonal variations, with the highest concentrations occurring from April to June and the lowest from January to March. The differences in radon concentrations between different areas were small and remained relatively stable. Construction disturbances in the active construction zones had a localized impact on radon concentrations,but due to favorable air diffusion conditions,this effect did not result in a widespread increase in radon levels. This suggests that the direct impact of human activities on regional radon concentrations is limited. According to the Pearson correlation coefficient analysis,a significant positive correlation was observed between temperature and radon concentrations,with radon levels increasing as temperatures rose at most measurement points. In contrast,the influence of wind speed on radon concentrations was more complex,with considerable variability in correlation across different points,likely influenced by other factors,warranting further investigation. This study provides data support and practical insights for long-term radon monitoring and health risk assessment at the Beishan URL.
