摘　　要：对空气中氡浓度的连续监测,要求仪器具有良好的时间响应性。本文针对连续测氡中导致延时的各种因素进行分析,研究了一种能消除子体残留影响,可连续测量变化氡浓度的延时修正方法。该方法已应用于南华大学研制的NRL-1连续测氡仪,实验结果表明,该方法有效、可靠。It is necessary that a radon instrument has good time-response for measuring continuously.All kinds of factors were analyzed thoroughly that cause time-delay in continuous measurement of radon.A method was developed by eliminating residual radon progeny and adequate ventilation.This method was applied in NRL-1 continuous radon meter that was developed by University of South China.The experimental results show that the method is very effective,can continuously measure radon concentration in the changing air without time-delay.
