Water (226)Ra concentration in springs was measured in regions with high indoor radon: Ural, North Caucasus (Russia), Niska Banja (Serbia), Piestany (Slovakia), and Issyk-Kul (Kyrgyzstan). This paper presents the results for (226)Ra concentration above 0.03 Bq l(-1). Radium in water could indicate indoor radon problem in the region and water investigation is useful at the initial stage of radon survey. Even low (226)Ra concentration in water (0.1-0.6 Bq l(-1)) caused high (226)Ra activity in travertine (up to 1500 Bq kg(-1)), which resulted in indoor radon concentration above 2000 Bq m(-3) (Niska Banja).
在室内氡含量较高的地区，如乌拉尔、北高加索（俄罗斯）、尼斯卡巴尼亚（塞尔维亚）、皮耶什佳尼（斯洛伐克）和伊塞克湖（吉尔吉斯斯坦），对泉水的镭 - 226浓度进行了测量。本文展示了镭 - 226浓度高于0.03 Bq l⁻¹ 的测量结果。水中的镭可能表明该地区存在室内氡问题，并且在氡调查的初始阶段，对水的调查是有用的。即使水中镭 - 226浓度较低（0.1 - 0.6 Bq l⁻¹），也会导致钙华中有较高的镭 - 226活度（高达1500 Bq kg⁻¹），这使得室内氡浓度高于2000 Bq m⁻³（尼斯卡巴尼亚）。
