A comprehensive study was made to measure the radon concentration in bottled water available in Iran market. The 222Rn concentration in 70 bottled water samples were measured by the sniffing mode technique and RTM 1688-2 (SARAD, Germany) in immediate sampling time and 3 months later for determination of radon decay. The measured radon concentration ranged from 0.003 to 0.618 Bq L in bottled water samples, which were much lower than the recommended value for radon in drinking water by WHO (100 Bq L) and United states environmental protection agency (USEPA) (11.1 Bq L). The annual effective dose of 222Rn due to ingestion bottled water was also evaluated in this research. The mean annual effective dose due to ingestion of radon in bottled water for adults, children, and infants were estimated to vary from 5.30 × 10 mSv, 4.90 × 10 mSv, and 2.15 × 10 mSv, respectively. Overall, this study indicated that the Iranian people receive no significant radiological risk due to exposure to radon concentration in bottled water brands common consumed in Iranian market.
本研究旨在测量伊朗市场上瓶装水的氡浓度。采用嗅探模式技术和 RTM 1688-2（SARAD，德国）对 70 个瓶装水样本中的 222Rn 浓度进行了即时采样和 3 个月后的测量，以确定氡的衰变。测量的瓶装水中氡浓度范围为 0.003 至 0.618 Bq/L，远低于世界卫生组织（100 Bq/L）和美国环境保护署（USEPA）（11.1 Bq/L）建议的饮用水中氡的浓度。本研究还评估了因饮用瓶装水摄入氡的年有效剂量。对于成年人、儿童和婴儿，因饮用瓶装水中氡而导致的年有效剂量分别估计为 5.30×10 mSv、4.90×10 mSv 和 2.15×10 mSv。总体而言，本研究表明，由于伊朗市场上常见的瓶装水品牌中氡浓度的暴露，伊朗人民没有受到显著的放射性风险。
