    近年南通市环境介质总α和总β放射性水平调查

    Investigation on Gross α and β Radioactivity of Environmental Samples in Nantong in Recent Years

      摘要
    • 摘要:
      目的 了解南通市环境介质天然放射性水平，积累南通市基线数据。
      方法 采集南通市环境中大气沉降灰、气溶胶、生活饮用水和食品，进行总α、总β放射性水平监测。
      结果 2014-2017年南通市气溶胶中总α放射性浓度为（0.23~1.65）mBq/m3，总β放射性浓度为（0.32~2.60）mBq/m3，大气沉降物中总α放射性浓度、总β放射性浓度分别为（4.7~44.0）Bq/m2，（37.1~104.0）Bq/m2；2013-2017年南通市生活饮用水年均总α放射性浓度为（0.009~0.050）Bq/L，总β放射性浓度为（0.060~0.124）Bq/L，各类食品中总α、总β放射性水平均值范围分别（0.40~11.72）Bq/kg，（31.99~130.74）Bq/kg。经方差分析，以上各样品年度间总α、总β放射性浓度差异均无统计学意义（P>0.05）。
      结论 近年来南通市环境中大气沉降灰、气溶胶、生活饮用水和食品总α、总β放射性未发现明显变化，人居环境是安全的。

       

      Abstract:
      Objectives To get the message of natural radioactivity level in environmental samples and accumulate the baseline data in Nantong.
      Methods Collecting atmospheric ash, aerosols, drinking water and food in the environment of Nantong, and monitoring the level of gross alpha and gross beta radioactivity.
      Results The gross alpha activities in aerosol were (0.23~1.65) mBq/m3, and the gross beta activities were (0.32~2.60) mBq/m3 in Nantong in 2014-2017, and the gross alpha and gross beta activities in atmospheric sediment were (4.7~44.0) Bq/m2 and (37.1~104.0) Bq/m2, respectively. The average annual gross alpha radioactivities of drinking water in Nantong were (0.009~0.050) Bq/L, and the gross beta radioactivities were (0.060~0.124) Bq/L. The mean range of gross alpha and gross beta radioactivities in various foods were (0.40~11.72) Bq/kg and (31.99~130.74) Bq/kg, respectively. The different between different samples were not significant.
      Conclusions In recent years, no significant change has been observed on gross α and β radioactivity in the deposited atmospheric ash, aerosols, drinking water and food, and no artificial polluted nuclide has been observed. The living environment in Nantong was safe.
