The Automatic Monitor and Control System of Radon Chamber

Radon chamber is an instrument to calibrate the radon monitors. The radon in the chamber is supplied from radon source., The radon concentration is changing dynamically by the reason of radon decay. A automatic monitor and control system is helpful to keep the stability of the radon concentration in the radon chamber. The paper introduced the mathematic model of radon supplement and proposed a fuzzy controller to improve the radon stability in the radon chamber, the related automatic monitor and control system is developed by this mathematic model. The structure of Radon chamber and the function of every component is presented in detail. The main performance parameter of the radon chamber such as airproof stability and radon concentration certification is discussed.
