摘要
论述了在铀矿开采和水冶过程中,产生的大量废石和尾矿中含有铀、镭等放射性元素,并有高的氡析出率,需要进行治理以降低氡析出等带来的环境影响。探讨了铀尾矿氡析出率的测量方法、测量布点网度、测量时间及其影响因素。
Large numbers of waste rock and tailings produced in mining of uranium ore and hydrometallurgy, of which there were radioactive elements, for instance, uranium and radium, and high niton eduction rate. It needed control to reduce environmental effect of niton eduction. The measurement methods of exhalation rate of niton from urnium tailing, distribution point number of measurement, measurement time and effect factor of measurement of niton exhalation rate were discussed.
