Abstract

As a standard instrument to calibrate the radon monitors, radon chamber is in urgent need with the deepening study on Radon and its progeny. According to the requirement of calibrating the radon monitors and radon detectors, the multifunctional and automatic controlled radon chamber is designed and constructed. By the reason of radon decay, the radon concentration in the chamber is continuously changing. The radon concentration must keep stability and homogeneity in order to calibrate the radon monitors and bio-culture. The supply and control of radon in the chamber is a critical problem in the design of Radon chamber. The paper introduced the mathematic model of dynamic radon replenishment according to the law of radon decay, three time parameters to replenish radon is discussed. The related automatic monitor and control system is developed by this mathematic model, the expected radon concentration can keep stability and homogeneity controlled by the system. The structure of radon chamber and the design flow system is presented in detail. The main performance parameter of the radon chamber such as airproof, stability and radon concentration certification is discussed. The research result can be used to calibrate the radon monitors, biological test on radiation environment and radiation medicine test.
