摘要: 为进一步了解核电站在正常运行时对周围环境中饮用水中总放射性水平的影响,于2021—2023年对大亚湾核电站周边3个采样点(城市客栈、鹏城、深圳)及对照点(佛冈)开展季度监测,对饮用水样品中的总α、总β进行了分析,活度浓度范围分别为0.004~0.033 Bq/L和0.020~0.150 Bq/L。结果表明,大亚湾核电站周围环境饮用水中放射性水平低于现行《生活饮用水卫生标准》对水质放射性指标的指导限值。

Abstract: To further understand the impact of nuclear power plant operation on the total radioactivity levels in surrounding drinking water, gross α and gross β in drinking water samples were collected and analyzed near Daya Bay nuclear power station from 2021 to 2023. Following the technical specifications for radiation environmental monitoring, quarterly monitoring was conducted at three sampling sites (Urban Inns, Pengcheng and Shenzhen city) and one control site (Fogang). The measured activity concentrations ranged from 0.004 to 0.033 Bq/L for gross α and 0.020 to 0.150 Bq/L for gross β. These results demonstrate that the radioactivity levels in drinking water around Daya Bay nuclear power station were all below the guidance limits specified in the current standards for drinking water quality.

Key words: Daya Bay nuclear power station, drinking water, gross α, gross β
