Indoor radon data monitored with several different recording systems in a controlled cellar were analyzed. The one-room cellar is carved into volcanic rock and presents an almost constant radon emanation throughout the year. Measurements were performed using the AlphaGUARD^?, Sun Nuclear^? 1027, DOSEman^? and RAD7^? radon monitors, and CR-39 Lantrack^? in a passive integrating detector. The radon concentrations measured by the active detection systems and averaged over the three-month measurement period ranged from 533 to 805?Bq?m^?3. The response of the passive detector system was a linear function for exposure times of one, two and three months. The data are discussed as a function of changes in the distribution of radon within the cellar and the response characteristics of the detection devices.
