北京市2011-2013年水中总α、总β放射性测量分析

Test and Analysis of Gross Alpha and Gross Beta Radioactive Levels in Water in Beijing from 2011 to 2013

  • 摘要: 目的 针对2011年3月11日日本福岛核事故,于2011-2013年采取相应的技术措施监测北京地区河、湖水与饮用水放射性污染水平,即该两类水中总α、总β放射性水平,确保饮用水的放射性污染水平不超过国家相关标准限值要求,为将来河、湖水的放射性水平可能发生的变化提供基础数据。

    方法 制定采集计划,每年分别在枯水期和丰水期采集河、湖水和饮用水,样品的采集覆盖北京市16个区(县),依据GB/T 5750.13-2006《生活饮用水标准检验方法》和GB 5749-2006《生活饮用水卫生标准》进行采集,采用相对比较测量法对水样总α、总β放射性进行测量分析。

    结果 河、湖水样品中,总α放射性水平算术平均值范围为0.06~0.15 Bq/L,总β放射性水平平均值范围为0.20~0.25 Bq/L;饮用水样品中,总α放射性水平算术平均值范围为0.09~0.11 Bq/L,总β放射性水平平均值范围为0.08~0.10 Bq/L。

    结论 2011-2013年北京地区河、湖水及饮用水在枯水期和丰水期的放射性水平均未超过国家生活饮用水卫生标准指导值。

     

    Abstract: Objective To control the radiation pollution levels of gross α and gross β in the rivers, lakes, and drinking water in Beijing area through taking corresponding surveillance measures from 2011 to 2013 against Fukushima nuclear accident on March 11 of 2011, to ensure the level in drinking water within national limits, and to provide baseline data for possible future radioactive level changes in rivers and lakes.

    Methods Samples of river and lake water and drinking water were collected as planned in dry season and wet season each year from 16 districts of Beijing according to the Standard Examination Methods for Drinking Water (GB/T 5750.13-2006) and the Standards for Drinking Water Quality (GB 5749-2006). Comparative measurement was applied to test and analyzed the gross α and β radioactive levels in the samples.

    Results In the samples of river and lake water, the arithmetic average values for gross α and gross β were in the range of 0.06-0.15 Bq/L and 0.20-0.25 Bq/L respectively. In the samples of drinking water, the arithmetic average values for gross α and gross β were in the range of 0.09-0.11 Bq/L and 0.08-0.10 Bq/L respectively.

    Conclusion From 2011 to 2013, the radioactive levels of river and lake water and drinking water in Beijing area, no matter in dry or wet period, are lower than the guideline values recommended by the national standard for drinking water.
