We report on continuous measurements of hourly concentration of Radon in outdoor air, carried out in Catania in the 1997–1998 period. The equipment allows determination of Radon concentration using α-particle spectrometry. The result show dependence on the meteorological conditions and especially on atmospheric stability. A typical behavior of Radon trend with a maximum near the sunrise and a minimum in the late afternoon is found for each month of the year. A good correlation is found between the variation of concentration of Radon and air pollution like CO. The Radon variation can be a valid index of dispersive power of atmosphere. A theoretical study is developed for confirming experimental observations. © 2000 American Institute of Physics.
