Abstract

Purpose

Variations in radon emissions have been reported during geophysical events, particularly earthquakes. Therefore, the present study aimed to determine the concentration of radon in groundwater drinking sources following the Sarpol-e Zahab earthquake in western Iran.

Methods

This study was conducted at 20 groundwater wells and springs in Sarpol-e Zahab City following the Ezgeleh earthquake. Radon concentration in the collected water samples was measured using an RTM 1688-2 radon monitor. The results were compared with pre-earthquake data as well as measurements obtained in 2024. In addition, the annual effective dose due to radon exposure through inhalation and ingestion was estimated. Statistical analyses were performed using SPSS version 16.

Results

Radon concentrations ranged from 3.566 to 15.829 Bq/L. The maximum annual effective doses were estimated to be 0.00332 mSv/year for inhalation and 0.0398 mSv/year for ingestion. Statistical analysis revealed no significant association between dissolved radon concentration and water temperature. Moreover, in all sampling locations, the estimated annual effective doses were below the reference level recommended by the World Health Organization (WHO).

Conclusion

Although the estimated annual effective doses were below the WHO reference level, the observed variations in groundwater radon concentrations before and after the earthquake suggest that seismic activity may influence dissolved radon levels. These findings support the inclusion of radon monitoring in post-earthquake groundwater quality surveillance programs in seismically active regions.

伊朗西部Sarpol-e Zahab及周边村庄地震后地下饮用水源中氡浓度的变化。

目的：在地球物理事件，特别是地震期间，已经报告了氡排放的变化。因此，本研究旨在确定伊朗西部Sarpol-e Zahab地震后地下水饮用源中的氡浓度。方法：在Ezgeleh地震后对Sarpol-e Zahab市的20口地下水井和泉水进行了研究。使用RTM 1688-2型氡监测仪测量所收集水样中的氡浓度。结果与地震前的数据以及2024年的测量结果进行了比较。此外，还估计了通过吸入和摄入接触氡的年有效剂量。采用SPSS 16进行统计分析。结果：氡浓度范围为3.566 ~ 15.829 Bq/L。估计吸入的最大年有效剂量为0.00332毫西弗/年，摄入的最大年有效剂量为0.0398毫西弗/年。统计分析显示，溶解氡浓度与水温无显著相关性。此外，在所有抽样地点，估计的年有效剂量都低于世界卫生组织（卫生组织）建议的参考水平。结论：虽然估计的年有效剂量低于世卫组织参考水平，但观测到的地震前后地下水氡浓度变化表明，地震活动可能影响溶解氡水平。这些发现支持将氡监测纳入地震活跃地区的震后地下水质量监测方案。图片摘要：补充信息：在线版本包含补充材料，可在https://doi.org/10.1007/s40201-026-01005-y上获得。
