Soil gas radon concentrations have been studied in an active fault zone of Ilgın, Konya, Turkey. At this seismically active fault zone 20 km long, 3-5 km width in the study area there are two faults and a graben in between them. The maximum radon and thoron concentrations are 32601 Bq/m3 and 17628 Bq/m3 , while the minimum values are 170 Bq/m3 and 103 Bq/m3 respectively. At 15 sampling points for radon the obtained values are higher than the average values. There has been a clear visibility of both 222Rn radon and 220Rn thoron anomalies in the area. The 222Rn and 220Rn have no positive or negative correlation at sampling points in the field.
