| Abstract | ||
| 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 | ||
