• Upon the indoor concentrations of radon short-lived decay products, the influence of the air-exchange has been studied. On the basis of a simple model, the degree of radioactive disequilibrium between radon short-lived decay products has been calculated. These calculations were performed taking into account of: (1) the collection efficiency of ventilation equipment at the side of air supply, (2) the removal of radioactivity by ventilation and wall deposition, (3) the degree of radioactive disequilibrium of radon decay products to radon in outdoor air, and (4) the ratio of radon concentration between indoors and outdoors. The result estimated agrees fairly well with that observed in room air.
