Determination of radon gas concentrations and annual effective dose in ground water samples in some regions in Anbar governorate

Abstract

In this work, we have measured the radon gas concentration in the environmental ground water sample of some regions in Anbar governorate by nuclear track detector (CR-39). The results of measurements indicate that the highest average radon gas concentration in ground water samples was found in AL-Ratba region which was equal  to (13.1±1.0 Bq/L), while the less average radon gas concentration was found in AL-Habbaneai region which was equal to (2.16±0.6 Bq/L), with an average value of  (5.89±2.6 Bq/L). The annual effective dose in ground water samples varied from (0.33 mSv/y) to (0.05 mSv/y) ,with an average value of (0.145±0.06 mSv/y).
