Abstract |
|
|
| Radon emanated from soil at southern part of Basrah Governorate, Iraq, have been investigated. The measurements were carried out in location in the sites, using CR-39 Solid State Nuclear Track Detectors SSNTDs. The location of sample points were selected according to mesh map covered the surveyed area, 2x2 km for each mesh area. The results of effective radium concentrations in these sites were found to vary from 1.149 Bq kg-1 to 2.543 Bq kg-1 . The outdoor radon levels concentrations in these sites were found to vary from 236.4 Bq m-3 to 523.2 Bq m-3, with average values of 367.8 Bq m-3. The average radon annual effective dose was 0.066 mSv y-1 for outdoor and 0.263 mSv y-1 for indoor. The results indicate that the soil are quite safe for occupancies and to be used as building materials. |
