摘　　要：研究铀矿山废水中放射性核素对周围水域的影响及这些核素在水域中的迁移状况。以国内某座铀矿山的排放废水作为研究对象,在尾矿库和废水净化厂房周围的河流中取样,采用电感耦合等离子体质谱法进行检测得到样品中铀、钍、钾的含量。所有监测点中,除了S-02号样品的238U和40K含量偏高外,其余监测点样品的238U和40K的含量都在天然本底范围内。所监测铀矿山周边水域中放射性核素未超过国家标准,水中放射性核素在随水流迁移过程中含量逐渐降低,到河流下游时,与天然本底水平相当。A uranium mine in China was used to study the effects of radionuclides in the wastewater on the surrounding surface water and its migration faerture.Samples were collected in the river around the tailingpond and wastewater purification plant.The content of uranium,thorium and potassium in the samples was determined by inductively coupled plasma mass spectrometry.In all the monitoring points,except in sample S-02,the contents of 238U and 40K were within the natural background.The radionuclides in the surrounding waters of the tailing pond have not exceeded the national standard.The concentrations of radionuclides in the water gradually decrease with the migration of water,and it is equivalent to the natural background level when it reaches the lower part of the river.
