(222)Rn measurements in water samples collected from 27 wells and 19 taps that were supplied from the investigated wells were conducted using the AlphaGUARD PQ 2000PRO radon gas analyser at sites across several geologic formations within the city of Bursa, Turkey. The measured radon concentrations ranged from 1.46 to 53.64 Bq l(-1) for well water and from 0.91 to 12.58 Bq l(-1) for tap water. Of the 27 sites sampled, only 7 had radon levels above the safe limit of 11.1 Bq l(-1) recommended by the USEPA. In general, all determined concentrations were well below the 100 Bq l(-1) revised reference level proposed by the European Union. These values of radon concentrations in water samples are compared with those reported from other countries. Doses resulting from the consumption of these waters were calculated. The minimum and the maximum annual mean effective doses due to (222)Rn intake through water consumption were 0.02 µSv a(-1) and 1.11 µSv a(-1), respectively.
在土耳其布尔萨市多个地质构造区域的不同地点，使用AlphaGUARD PQ 2000PRO氡气分析仪，对从27口水井以及由这些调查水井供水的19个水龙头采集的水样进行了（222）Rn测量。井水的测量氡浓度范围为1.46至53.64 Bq l⁻¹，自来水的测量氡浓度范围为0.91至12.58 Bq l⁻¹。在采样的27个地点中，只有7个地点的氡水平高于美国环境保护局推荐的11.1 Bq l⁻¹安全限值。总体而言，所有测定浓度均远低于欧盟提出的100 Bq l⁻¹修订参考水平。将水样中的这些氡浓度值与其他国家报告的值进行了比较。计算了饮用这些水所产生的剂量。通过饮水摄入（222）Rn导致的最低和最高年平均有效剂量分别为0.02 µSv a⁻¹和1.11 µSv a⁻¹。
