In soil samples collected from 58 points of 7 different lithological units that appear most often in Slovenia, emanation fraction of 222Rn and porosity have been determined. Emanation fraction ranged from 0.010 to 0.547 and varied substantially among lithological units, as well as within the same lithological unit. The highest average value was found in soil over sea and lake deposits (0.340) and the lowest, over metamorphic rocks (0.029). Based on the data measured, radon concentration in soil gas was calculated and compared with the values obtained previously at the same points by exposing solid state nuclear track detectors.
