Radon concentration in soil-gas and in the atmospheric air has been studied around Mysore city (12 degrees N and 76 degrees E) using Solid State Nuclear Track Detectors. The radon in soil-gas is found to be higher at a depth of I m than at a depth of 0.5 m from the ground surface. The higher radon concentration in soil was observed near Chamundi Hills and Karigatta village with average values of 5.94 kBq.m(-3) and 5.32 kBq.m(-3) at 1 m depth from the ground surface. Seasonal variations in radon in soil gas shows that, the concentration is lower in summer with an average value of 0.60 kBq.m(-3) and higher in monsoon season with an average value of 4.70 kBq.m(-3). Estimation of Ra-226 in soil at these locations is also made using HPGe detector. The activity of Ra-226, varies from 4.82 to 74.23 Bq.kg(-1) with an average value of 32.11 Bq.kg(-1). Radon concentrations in soil-gas shows good correlation with the activity of Ra-226 in soil with a correlation coefficient of 0.76
