By the reason of radon decay, the radon concentration in the chamber is continuously changing. The supply and control of radon in the chamber is necessary to keep the stability of the radon concentration. In the standard radon chamber of HD-5, dynamic radon replenishment model was adopted according to the law of radon decay, but the effects of temperature and humidity on the radon concentration was neglected. In this paper, fuzzy control model is presented to eliminate these effects. A fuzzy
