In this study, the fission track registration technique with the CR-39 detector are using to determination the uranium concentrations for 13 samples of teeth distributed in Al-Fluja City and by 0.5gm in weight and 1.5 mm in thickness . The uranium concentrations in teeth samples measured by using fission tracks registration in CR-39 track detector that caused by the bombardment of (U) with thermal neutrons from 241 Am-Be neutron source that has flux of 5 ×103 n cm-2 s-1. The concentrations values were calculated by a comparison with standard samples. The results showed that the maximum value of uranium is 0.12 ppm and the minimum is 0.58 ppm.
