摘　　要：介绍了一种铀尾矿表面氡析出率测量新方法——活性炭吸附法和γ能谱法。同时介绍了活性炭吸附法采样器和仪器的研制及性能、特点,采样器和仪器的刻度,条件试验以及与局部静态法的对比测量。通过用该方法对铀尾矿库现场连续一年的监测,观测了铀尾矿库年氡析出率的变化规律,总结出年平均氡析出率的最佳测量季节和测量条件。给出了γ能谱法参数测量、计算方法及试验的结果。Two new monitoring methods of radon release rate from uranium tailings are introduced. They are the active carbon absorption and γ energy spectrum method. The instrument and sampler of active carbon absorption is presented with the manufacture, function, performance and calibration, the conditional test of the method and its measuring contrast to that of local static method. One-year continuous in-site monitoring of radon release rate of uranium tailings was done. The annual change regularity of radon release rate from uranium tailings was observed. The optimum season and condition of monitoring the annual average radon release rate are summarized. The parameter monitoring, calculating method and experimentation of γ energy spectrum method is discussed.
