中文摘要	以内蒙古东乌旗地区为例，分析地下水化学成分、同位素D，^18O和^3H以及铀、氡元素含量，研究干旱地区地下水水化学类型、成因、年龄和放射性环境问题。结果表明：①东乌旗地区地下水类型有HCO3-Na型，主要为氧化环境的潜水；SO4·Cl·HCO3-Na、SO4·Cl-Na型，主要为氧化-还原环境混合成因承压水；Cl-Na，Cl·SO4-Na型，为还原环境水化学特征；②同位素D，^18O组成特征表明，地下水来自大气降水渗入补给，又表现出不同于大气降水中D，^18O的差异性；③放射性同位素^3H显示裂隙水、层间承压水可能主要来源于20世纪60年代以前，潜水主要是近期降水结果；④地下水存在一定的放射性危害，作为饮用水水源的砂岩含水层水，应加强对生活水源铀、氡含量检测；⑤地下水中的氡具有两面性。
英文摘要	In this paper, the chemical composition of groundwater and the contents of D, ^18O and ^3H as well as uranium and radon in groundwater in Dongwu Banner, Inner Mongolia Autonomous Region, are analyzed, and the chemical types, formation causes, age and emissive environment of groundwater in arid areas are researched. The results are as follows：（1） Groundwater in Dongwu Banner is dominated by HCO3-Na type, and it is manly phreatic water under the oxidation environment; secondly dominated by SO4·Cl·HCO3-Na, SO4·Cl-Na type, and it is mainly pressure water under the oxidation-deoxidization environment and mixed formation causes; and then by Cl-Na, Cl·SO4-Na type, and it is reflected by the chemical properties of deoxidization environment; （2） The composition characteristics of isotopes of D and ^18O reveal that groundwater in the study area is recharged by infiltration of precipitation, but they are different from that of precipitation to some extent; （3） The content of ^3H reveals that the crevice-water and pressure water was possibly recharged before the 1960s, and phreatic water was manly recharged by precipitation recently; （4） There is certain emissive harmfulness in groundwater, as a drinking water source, the detection on contents of uranium and radon in the sandstone aquifer should be enhanced so as to avoid the harmfulness to people＇s health from drinking water sources with uranium mineralization; （5） The effect of radon in groundwater has two aspects, on the one hand radon in drinking water is harmful to people＇s heath if its content is higher than the standard, but the drinking water standard can be achieved if water is stored in open air or boiled; on the other hand the bath with radon-water can cure some sicknesses, so radon-water can be regarded as resources to exploit and utilize.
