甘肃省集中式饮用水水源放射性水平调查(2017-2018年)

Investigation on radioactive level of centralized drinking water sources in Gansu province(2017-2018)

为了掌握甘肃省地级市(州)集中式饮用水水源放射性水平,分别于2017、2018年对全省地级市(州)22个集中式饮用水水源地样品中的总α、总β、U、Th、226 Ra放射性浓度进行了调查。结果表明,所调查集中式饮用水源地水体中放射性核素浓度与20世纪80年代全国放射性本底调查时当地环境天然本底水平相近。

In order to know the radioactivity level of centralized drinking water sources in prefecture-level cities(states)of Gansu Province,the total alpha,total beta,U,Th,and 226 Ra radioactivity in centralized drinking water sources in prefecture-level cities(states)of Gansu Province were investigated in 2017 and 2018 respectively.The results show that the concentration of radionuclide activity in the water body of the centralized drinking water sources is at the natural background level of the local environment.And the corresponding environmental management countermeasures are put forward for the drinking water sources.
