摘要：Abstract In this work, uranium concentrations and annual effective dose in tap water samples for Al-Manathera and Al-Herra Regions of Al-Najaf, Iraq were determined using a solid-state nuclear track detector (CR-39 detector). Furthermore, we determined the uranium isotopes (238U, 235U and 234U) for all tap water samples under study. The tap water samples are collected nearly from all regions of Al-Manathera and Al-Herra for 22 regions. Thus, the total studied samples are 40. The results indicate that, the average values of uranium concentrations and the annual effective dose in Al-Manathera were larger than the average value at Al-Herra Regions. We concluded that the average value of the uranium concentrations and total average of the annual effective dose in tap waters samples under study were lower than the recommended value of ICRP (1.9 μg/l) and 1 mSv respectively. Therefore, most of the samples could be used without any healthy risk depending on the level of natural uranium concentrations.
