This paper describes a new approach to the separation of their effects, which effectively allows continuous estimation of both radon entry rate and air exchange rate from simultaneous tracer gas (CO) and radon gas measurement data. It is based on a state-space statistical model permitting efficient calculations. After introducing the statistical model formally, its performance is demonstrated on real data from measurements from an experimental room. To verify our method, radon entry rate calculated via proposed statistical model was compared with known reference value. The results from several days of measurement indicated fairly good agreement (up to 5% between reference value radon entry rate and its value calculated via proposed method, on average).
