The Austrian Radon Project started in 1992 and ended in 2001. The Austrian Radon Project had two aims: firstly, finding areas of enhanced indoor radon concentration for future radon mitigations, and, secondly, defining areas with elevated radon risk where radon safe construction is necessary for new houses. The project was based on systematic indoor measurements in randomly selected houses using different types of detectors. Successful intercomparison tests were made in a radon chamber, but simultaneous measurements by different detectors normally used in homes deviated sometimes up to a factor of two. We have to assume that this results from manipulations of the detectors by the inhabitants. The mean radon concentration in Austrian homes was found to be 99 Bq m(-3). A radon potential was derived from the results of the measurements and the information received from questionnaires. This radon potential was defined as an expected radon concentration in a standard situation and characterizes the radon risk from ground sources with all the influences of different living situations eliminated. A mean radon potential was computed for every municipality and the information is displayed as a map. The uncertainty and the reliability of the classification of municipalities according to the radon potential are discussed in more detail and compared with results from Switzerland.
奥地利氡项目始于1992年，于2001年结束。该项目有两个目标：其一，找出室内氡浓度升高的区域，以便未来采取氡减排措施；其二，确定氡风险较高的区域，在这些区域新建房屋需要进行氡安全施工。该项目基于使用不同类型探测器对随机选取房屋进行的系统室内测量。在氡室中进行了成功的比对测试，但家庭中通常使用的不同探测器同时进行的测量有时偏差高达两倍。我们不得不认为这是居民对探测器进行操作所致。奥地利家庭中的平均氡浓度为99贝克勒尔每立方米。根据测量结果和问卷调查获得的信息得出了氡潜能。这种氡潜能被定义为标准情况下的预期氡浓度，它表征了在消除不同生活状况的所有影响后，来自地源的氡风险。为每个市镇计算了平均氡潜能，并将信息以地图形式展示。文中更详细地讨论了根据氡潜能对市镇进行分类的不确定性和可靠性，并与瑞士的结果进行了比较。
