在安装扩散曝气系统之前和之后，对整个农村社区的家庭空气和生活供水中的氡进行了测量，该系统将水源处的水氡从大约20000 pCi/L减少到了1000 pCi/L。对空气氡的持续监测表明，一些家庭的用水会产生短期影响。水源中的氡减少后，未观察到住宅中空气氡水平的持续变化。讨论了阻碍水对空气氡贡献检测的环境和分析因素，并对未来研究的设计提出了建议。包括12个参考文献、表格、图表。

Radon in home air and domestic water supplies was measured throughout a rural community before and after the installation of a diffused aeration system that reduced water radon at the source from approximately 20,000 to < 1,000 pCi/L. Continuous monitoring of air radon indicated short-term contributions from water use in some homes. Following reduction of radon in the water source, no consistent changes in the air radon levels in the homes were observed. Environmental and analytical factors that obscured the detection of the contribution of water to the air radon are discussed, and recommendations are made for the design of future studies.
