Radiological assessment of bottled mineral waters and thermal spring waters collected from various natural sources in Turkey was carried out using gross alpha and gross beta counting techniques. For 40 samples of bottled mineral water, the mean gross alpha activity concentration was determined to be 164 mBq l(-1) (min.:7 mBq l(-1); max.: 3042 mBq l(-1)), whereas the gross beta activity concentration was found to be 555 mBq l(-1) (min.: 21 mBq l(-1); max.: 4845 mBq l(-1)). For 24 samples of thermal spring water, the mean gross alpha activity concentration was obtained to be 663 mBq l(-1) (min.: 18 mBq l(-1); max.: 3070 mBq l(-1)). The gross beta activity concentration for these samples, on the other hand, was determined to be 3314 mBq l(-1) (min.: 79 mBq l(-1); max.: 17955 mBq l(-1)). These values lead to the average annual effective doses of 313 µSv for mineral waters and 1805 µSv for thermal spa waters, which are found to be higher than those recommended for drinking waters by the World Health Organization. It should be noted, however, that one will get less dose from mineral waters since the daily consumption is much lower than 2 l that these calculations assume.
采用总α和总β计数技术，对从土耳其不同天然水源采集的瓶装矿泉水和温泉水进行了放射学评估。对于40份瓶装矿泉水样本，测定的总α活度浓度平均值为164 mBq l(-1)（最小值：7 mBq l(-1)；最大值：3042 mBq l(-1)），而总β活度浓度为555 mBq l(-1)（最小值：21 mBq l(-1)；最大值：4845 mBq l(-1)）。对于24份温泉水样本，总α活度浓度平均值为663 mBq l(-1)（最小值：18 mBq l(-1)；最大值：3070 mBq l(-1)）。另一方面，这些样本的总β活度浓度测定为3314 mBq l(-1)（最小值：79 mBq l(-1)；最大值：17955 mBq l(-1)）。这些数值导致矿泉水的年均有效剂量为313 µSv，温泉水为1805 µSv，发现高于世界卫生组织对饮用水推荐的剂量。然而，应该指出的是，由于每日消费量远低于这些计算所假设的2升，人们从矿泉水中获得的剂量会更少。
