一种连续测氡延时修正方法

Method of Time-Delay Correction in Continuous Measuring Radon

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。

Abstract: 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.
