Ramsar is one of the highest background radiation areas in the world, whose natural radioactivity is due to (238)U natural series and its decay products, especially (226)Ra and (220)Rn, which have been brought to the surface by water of hot springs. In this study, radon concentration in 14 drinking water sources of the Ramsar region has been measured with the PRASSI system. The results show all of the water supplies have radon concentration greater than 10kBq/m(3) as normal level. Moreover, the estimated mean annual radiation dose to public due to waterborne radon has also been evaluated.
拉姆萨尔是世界上天然本底辐射水平最高的地区之一，其天然放射性归因于（238）U天然系列及其衰变产物，尤其是（226）Ra和（220）Rn，它们通过温泉水被带到地表。在本研究中，使用PRASSI系统测量了拉姆萨尔地区14个饮用水源中的氡浓度。结果表明，所有供水的氡浓度均高于正常水平的10kBq/m³。此外，还评估了公众因水中氡而产生的估计年辐射剂量。
