In Austria a comprehensive study on radiation exposure in waterworks was conducted. The aim of this study was to evaluate the risks for the affected employees. On the basis of geographical, geological and hydrological aspects, 21 waterworks were selected. A total of 85 passive short-term measurements and measurements with active devices for the detection of 222Rn were conducted and compared regarding their applicability to waterworks. Additionally, the results of 47 passive combined 222Rn/220Rn measurements for the detection of 220Rn are part of this paper. 222Rn was determined in row water samples. The influences of water flow rates and of the 222Rn activity concentration in water on the 222Rn activity concentration in indoor air of water supplies were investigated. On the basis of the results of radon measurements at 165 points, the annual effective doses for 74 persons of the staff were determined.
在奥地利，针对自来水厂的辐射暴露开展了一项全面研究。该研究的目的是评估受影响员工面临的风险。基于地理、地质和水文方面的因素，选取了21家自来水厂。总共进行了85次被动式短期测量以及使用主动式设备检测222Rn的测量，并就其在自来水厂的适用性进行了比较。此外，本文还包含47次用于检测220Rn的被动式222Rn/220Rn联合测量结果。在原水样中测定了222Rn。研究了水流速率以及水中222Rn活度浓度对供水室内空气中222Rn活度浓度的影响。根据165个点的氡测量结果，确定了74名工作人员的年有效剂量。
