Abstract The standard laboratory of radon plays an important role in the tracing and transmitting of value of radon concentration. But there are many problems in the process of building the standard laboratory of radon, which are gas leaking of solid radon source, inconformity between theoretical value and experimental value of radon concentration in laboratory, and crystallization of liquid radon source. Measures were taken to solve these problems, such as changing the gas washing canal of radon, optimizing the model of gas washing, multiple sealing and filtering, building empirical curve, and so on. It indicated that the relative deviation between theoretical value and experimental value of radon concentration in laboratory was less than ±3.8%, and the long time stability of liquid radon source less than 0.7%, which meet the requirment of measurment and methods established metrology.

Key words： metrology radon concentration radon laboratory building standard concentration control
