| 目的 掌握秦山核电站运行期间周围饮用水和食品中90Sr的放射性水平及变化趋势。方法 在2012—2022年每年分别于丰水期(5月)及枯水期(10月)选取秦山核电站周围30 km范围内采集水源水、出厂水和末梢水,测定水中90Sr含量;并根据当地居民饮食习惯,采集大米、包菜、鲻鱼、鲫鱼等4种食品,依据二-(2-乙基己基)磷酸萃取色层法对样品中的90Sr放射性活度浓度进行测定并分析。结果 2012—2022年秦山核电站周围水源水、出厂水和末梢水的90Sr放射性活度浓度范围分别为3.73~11.89、2.95~9.83和3.12~8.70 mBq/L,历年结果无明显波动。4种食品大米、包菜、鲻鱼、鲫鱼中90Sr放射性活度浓度范围分别为0.02~0.46 Bq/kg(干重)、0.26~1.07 Bq/kg(鲜重)、0.38~1.05 Bq/kg(鲜重)和0.08~1.32 Bq/kg(鲜重),结果均低于国家标准限值。结论 2012—2022年秦山核电站周围饮用水和食品中90Sr放射性水平处于本底水平且保持平稳。 |

| Objective To investigate the radioactivity levels and variation trends of 90Sr in drinking water and food around the Qinshan Nuclear Power Plant in operation. Methods From 2012 to 2022, the source, factory, and tap water was collected within 30 km around the Qinshan Nuclear Power Plant during the wet and dry seasons (i.e., May and October, respectively) each year to determine the 90Sr concentration in water. According to the dietary habits of local residents, four kinds of food, including rice, cabbage, mullet, and crucian carp, were collected to determine and analyze the 90Sr radioactivity concentration in food using the bis-(2-ethylhexyl) phosphoric acid extraction chromatographic method. Results From 2012 to 2022, the 90Sr radioactivity concentrations in the source, factory, and tap water around the Qinshan Nuclear Power Plant ranged from 3.73 to 11.89 mBq/L, 2.95 to 9.83 mBq/L, and 3.12 to 8.70 mBq/L, respectively, showing nonsignificant fluctuations over the years. The 90Sr radioactivity concentrations in rice, cabbage, mullet, and crucian carp ranged from 0.02 to 0.46 Bq/kg (dry weight), 0.26 to 1.07 Bq/kg (fresh weight), 0.38 to 1.05 Bq/kg (fresh weight), and 0.08 to 1.32 Bq/kg (fresh weight), respectively, all below the national standard limits. Conclusions From 2012 to 2022, the 90Sr radioactivity levels in drinking water and food around the Qinshan Nuclear Power Plant were at the background level and remained stable. |
