As part of the national survey to evaluate natural radioactivity in the environment, concentration levels of total radioactivity and natural uranium have been analysed in drinking water samples. A survey to study natural radioactivity in drinking waters was carried out in the Van province, East Turkey. Twenty-three samples of drinking water were collected in the Van province and analysed for total α, total β and (238)U activity. The total α and total β activities were counted by using the α/β counter of the multi-detector low background system (PIC MPC-9604), and the (238)U concentrations were determined by inductively coupled plasma-mass spectrometry (Thermo Scientific Element 2). The samples were categorised according to origin: tap, spring or mineral supply. The activity concentrations for total α were found to range from 0.002 to 0.030 Bq L(-1) and for total β from 0.023 to 1.351 Bq L(-1). Uranium concentrations ranging from 0.562 to 14.710 μg L(-1) were observed in drinking waters. Following the World Health Organisation rules, all investigated waters can be used as drinking water.
作为评估环境中天然放射性的全国性调查的一部分，已对饮用水样本中的总放射性和天然铀浓度水平进行了分析。在土耳其东部的凡省开展了一项研究饮用水中天然放射性的调查。在凡省采集了23份饮用水样本，并分析了总α、总β和²³⁸U活度。总α和总β活度通过多探测器低本底系统（PIC MPC - 9604）的α/β计数器进行计数，²³⁸U浓度通过电感耦合等离子体质谱法（赛默飞世尔科技Element 2）测定。样本根据来源分类：自来水、泉水或矿泉水。总α活度浓度范围为0.002至0.030 Bq L⁻¹，总β活度浓度范围为0.023至1.351 Bq L⁻¹。在饮用水中观察到铀浓度范围为0.562至14.710 μg L⁻¹。按照世界卫生组织的规定，所有调查的水均可作为饮用水使用。
