Abstract

Water usually contains small quantities of radioactivity. The presence of significant levels of radioactivity in drinking water sources poses potential health risks to the public. Consequently, determining the concentrations of gross alpha and gross beta activity in water is essential for ensuring water safety. Thirteen commercially bottled mineral water samples were collected from Moroccan markets and analyzed using the Liquid Scintillation Counting technique, based on the ISO 11704:2018 method. The results show that the activity concentrations range from a minimum below the lower limit of detection to a maximum of 0.21 ± 0.02 and 0.15 ± 0.01 Bq·L-1 for gross alpha and gross beta, respectively. The concentrations of anions and cations are within recommended limits for drinking water. For each sample, the annual effective dose was calculated and lifetime cancer risks were estimated. The levels of the annual effective dose and lifetime cancer risk were all below the World Health Organization's recommended values for drinking water quality.

使用摩洛哥瓶装矿泉水中总α和β活性浓度估算年有效剂量和相关健康风险。

水通常含有少量的放射性物质。饮用水源中存在大量放射性物质，对公众构成潜在的健康风险。因此，确定水中总α和总β活性的浓度对确保水安全至关重要。从摩洛哥市场收集了13个商业瓶装矿泉水样品，并根据ISO 11704:2018方法使用液体闪烁计数技术进行了分析。结果表明，总α和总β的活性浓度最小值低于检测下限，最大值分别为0.21±0.02和0.15±0.01 Bq·L-1。阴离子和阳离子的浓度在饮用水的建议限度之内。对于每个样本，计算年有效剂量并估计终生癌症风险。年有效剂量和终生癌症风险水平均低于世界卫生组织建议的饮用水质量值。亮点:

期刊介绍： Radiation Protection Dosimetry covers all aspects of personal and environmental dosimetry and monitoring, for both ionising and non-ionising radiations. This includes biological aspects, physical concepts, biophysical dosimetry, external and internal personal dosimetry and monitoring, environmental and workplace monitoring, accident dosimetry, and dosimetry related to the protection of patients. Particular emphasis is placed on papers covering the fundamentals of dosimetry; units, radiation quantities and conversion factors. Papers covering archaeological dating are included only if the fundamental measurement method or technique, such as thermoluminescence, has direct application to personal dosimetry measurements. Papers covering the dosimetric aspects of radon or other naturally occurring radioactive materials and low level radiation are included. Animal experiments and ecological sample measurements are not included unless there is a significant relevant content reason.
