昆山市不同饮用水源中放射性水平的调查

Radioactivity in Different Sources Drinking Water in Kunshan

摘要

摘要:
目的了解昆山市居民不同饮用水源水体中的放射性水平。
方法 2013年2月至2014年2月采集市政末梢水、水源水、出厂水、深井水及昆山产桶装饮用水样本共176份, 按照《生活饮用水标准检验方法放射性指标》(GB/T 5750.13-2006) 对总α和总β放射性水平进行分析, 依据《生活饮用水卫生标准》(GB 5749-2006) 进行判定。
结果所有水样监测结果均低于标准限值。
结论昆山市的饮用水没有受到人工放射性核素的污染, 处于正常的天然放射性本底水平, 应进一步加强监测。

Abstract:
Objectives To learn radioactivity in different sources of drinking waters in Kunshan.
Methods A total of 176 drinking water samples, including tap water, source water, treated water, well water and bottled water samples produced in Kunshan were collected; the total α and total β radioactivity were analyzed according to "Standard Examination Methods for Drinking Water Radiological Parameters"(GB/T 5750.13-2006) from February 2013 to February 2014, and the results were determined according to "standards for drinking water quality"(GB 5749-2006).
Results The radioactivity of all water samples was below the standard limits.
Conclusion Drinking water samples were not contaminated by artificial radionuclides in Kunshan, and the radioactivity was in natural normal background level.Monitoring radioactivity in drinking water should be further strengthened.
