This paper examines the data obtained in the area of Paratunka geothermal site since 1998 throughout 2002. Data analyses revealed a relationship between the electric field intensity (EFI) and exhalation of radon into the ground atmosphere. Both daily and seasonal variations in values of EFI are correlated with the run-out of subsoil radon into the atmosphere. It explains a great difference between maximal and minimal value of about 90 V/pm averaged over the total time of observation in conditions of good weather. Global daily variations and meteorological processes complicate the relationship between the electric field intensity and run-out of radon into the atmosphere.
