Abstract
Introduction: This study concentrated on the radiological analysis of natural alpha particle emission rates from human teeth as biomarkers of radiation exposure and environmental pollution. Materials and Methods: Sixty eight teeth samples (27 males, 41 females) collected from hospitals distributed across the Najaf governorate including many districts in Iraq. Alpha particle emission rates measured using nuclear track detector (CR-39). Results: The emission rate of alpha particles in female teeth was 0.0396 ±0.0070 mBq cm-2, which is somewhat higher than male teeth (0.0390 ±0.0048 mBq cm-2). There are not significant differences between emission rate of alpha particles in female and male teeth. Whereas, the emission rate of alpha particles in the teeth in Kufa (0.0417±0.0057 mBq cm-2) somewhat larger than in the teeth in Najaf (0.0384±0.0053 mBq cm-2). Conclusion: It is concluded that the emission of alpha particle rate was low, as compared with results obtained from worldwide researches, so has no negative consequence for people health.
