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.
