摘　　要：对基于局部静态收集法的表面氡析出率的快速测量方法进行了研究.通过实验给出了建议的累积时间和测量程序.用静电收集法测氡仪对快速测量方法进行了实验测量验证.本方法的测量结果与活性炭-γ谱法的测量结果一致.不需要考虑泄露和反扩散影响的修正.用建议的测量程序测量时,取样泵取样对氡的累积带来的干扰可忽略不计.The rapid method for measuring radon exhalation rate based on the local static collection method is studied. The proposed cumulative time and measuring procedures are given by the experiment. The rapid measuring method is verified by experimental measure- ments using the electrostatic radon monitor. The result is consistent with the activated char- coal absorption--Tenergy spectrum method. The leakage and back-diffusion effect are not needed to be considered. The faults arising from pump-sampling way to the accumulation of radon can be ignored when the proposed measuring procedures is being used.
