摘要

为一个2.84m3的氡室研制了一套氡浓度控制系统。采用控制氡室与外界换气量的方法调节氡室中氡浓度。换气量采用短周期开关控制的方法-脉冲宽度控制法（PWM）

换气周期为10min。采用了氡快速补充和快速排放装置。氡室中使用一个扩散式固体氡源。系统用计算机自动控制

氡浓度建立时间小于4h

控制平稳

长时间稳定性优于2%。

Abstract

A radon concentration control system for a radon chamber (2.84m3) was developed. The radon concentration in the chamber can be controlled by adjusting air exhaust flow rate through the method of Pulse Width Modulation(PWM). A controlling cycle is 10 minutes

with a device to quickly supply and discharge radon. A solid radon source was used in the radon chamber. The system was controlled by computer. The equilibrium time of radon concentration was less than 4 hours. The stability of long time control was better than 2%.
