The uranium concentrations in teeth samples were determined using a Lexan nuclear track detector and a fission tracks registration methodology for 25 samples of teeth, each weighing (0.7) grams and measuring (2) mm in thickness, Teeth were collected from private clinics and government hospitals in different areas in the city of Samawa for both males and females. Thermal neutron bombardment of (U) from a (241Am-Be) neutron source with a flux of (5×103 .n.cm-2 .s-1 ) for one week. The outcomes obtained showed that the highest value of uranium concentrations was in a woman, a 33-year-old, and the lowest uranium concentration was in a 7-year-old child. Uranium concentration results vary according to the person’s location, gender and age. The findings revealed that the uranium concentration was high in females was higher than the concentration of uranium in males by an average of (81.13%).
