摘要
介绍了西湖水体天然放射性水平的检测结果。在2016年杭州G20峰会召开前后,对西湖以及周围水系进行了布点、采样、测量,分析了水中总α、总β、90Sr、137Cs、226Ra、Th、U的活度浓度,并与2012—2015年平均水平进行比较分析。结果表明:西湖水体天然放射性水平和水域中放射性核素的波动始终在国家相关水质要求范围之内。
this research shows the results of the natural radioactivity level in west lake. In 2016,selecting the distribution location of the West lake and surrounding water system,then sampling,measuring and analyzing the activity concentration of the alpha,beta,90 Sr,137 Cs,226 Ra,Th,U in water,and compared with2012—2015 average statistics. The results show that the natural radioactivity level and the fluctuation of radionuclides in West lake are always within the range of the national water quality requirements.
