Abstract
The purpose of this study was to measure the radon concentration in the air inside Darbandikhan and Peshraw tunnels located at Sulaimani governorate. The concentration of Rn222 have been determined using CR-39 Solid–State Nuclear Track Detector Technique. It was found that the range of radon concentration inside Darbandikhan tunnel was (305.8 - 391.34) Bq/m3 , and that of Peshraw tunnel was (2042.9 - 4277.89) Bq/m3. A concentration of several thousand Bq/m3 was observed at the inner most area of the Peshraw tunnel towards southern geographic which indicates that the radon concentration in the tunnel is basically governed by diffusion and mixing of radon gas with air.
