Radon emanated from soil at Shutt- Al-Basrah river-banks and Basrah Sport City have been investigated. The measurements were carried out in 17 points in four depths from the surface, using CR-39 and LR-115 solid state nuclear track detectors and RAD7 instrument. The location of sample points were selected according to mesh map covered the surveyed area, 5x5 km2 for each mesh area. The results of outdoor radon levels concentrations in these sites were found to vary from 1439±90 Bq m-3 to 38765±2432 Bq m-3, with average values of 5292 Bq m-3. The radon annual effective dose ranged from 1.60 mSv y-1 to 9.12 mSv y-1 . The corresponding mean values of annual effective dose for the sites was 3.02 mSv y-1, indicates that the open area basements, storage areas and tunnels are safe occupancies.
