Determination of Radon Concentration and Annual Effective Dose Inside Houses in Left Side of Mosul City During Winter

In this study, radon concentration, annual effective dose, potential alpha energy concentration (PAEC), and average of lung cancer per million persons from radon were measured using (closed can technique) containing CR-39 nuclear track detector. Measurements were carried during winter season inside twenty four hoses in eight locations in the left side of Mosul City. The average radon concentration ranged between (52.97±5.315 to 74.98±5.433) Bq.m -3 with an average value (62.36±7.518) Bq.m -3 which is much lower than the recommended by ICRP action level (200-600) Bq.m -3 . The results showed that the potential alpha energy concentration ranged between (5.71×10 -3 ±0.566 ×10 -3 to 8.11×10 -3 ±0.586 ×10 -3 ) WLM with an average value (6.7×10 -3 ±0.820×10 -3 ) WLM, while the annual effective dose ranged between (1.34±0.134 to 1.89±0.137) mSvy -1 with an average value (1.57±0.189) mSvy -1 . It is observed that this value less than the recommended levels (3-10) mSvy -1 reported by ICRP. The average lung cancer cases per year per million persons were found to be 28.3±3.404, there were no induction of existence of radon problems in this survey.
