目的陕西关中地热资源丰富,开发利用广泛,了解西安南郊长安区地热温泉水开发利用对室内环境及人体健康的影响。方法通过对西安市长安区地热温泉水样的采集,应用FD-125氡钍分析仪测定地热温泉水中氡的浓度,应用Tracerlab crs-z-s离子色谱分析仪测定温泉水中阴阳离子的浓度。结果发现长安区不同地方的温泉水水中氡含量水平差异较大,区内西北政法大学等高校和滦镇、东大镇各种渔场的温泉水中的氡含量较高,氡含量最高达142.94 kBq·m-3,同时发现离子浓度水平总体偏高。结论使用这些地方的温泉水会对人体产生一定剂量的辐射,应加强防护措施;温泉水中氡浓度与离子浓度呈正相关关系。
Aim Shaanxi Province is rich in geothermal resources and has a wide range of development and utilization. It has an understanding of the impact of the development and utilization of geothermal spring water on the indoor environment and human health in Chang’an District in the southern suburbs of Xi’an. Methods The concentration of radon in geothermal spring water was determined by FD-125 radon-thoron analyzer. The concentration of anion and cation in hot spring water was determined by Tracerlab crs-z-s ion chromatograph. The results showed that radon content in hot spring water varied greatly in different places in Chang’an District. The radon content in spring water of various fishing grounds such as Northwest University of Political Science and Law, Luan and Dongdazhen was high, and the radon content reached 142.94 kBq · m-3, also found that the overall level of ion concentration is high. Conclusion The use of hot spring water in these areas will produce a dose of radiation on the human body, should strengthen protective measures; radon concentration in hot spring water and ion concentration was positively correlated.
