Title : MEASUREMENT OF THE URANIUM CONCENTRATIONS IN THE ADULTS TEETH BY CR-39 DETECTOR AT KARBALA CITY/IRAQ

Abstract :

Using the CR-39 detector the fission-track registration technique was employed for determination of the uranium (U) concentration for 10 tooth samples found at Karbala city in Iraq. Each sample was 1.5 mm thick and 0.5 g in weight. Measurement of the uranium concentration in the samples was made by employing the CR-39 track detector to follow fission tracks caused by bombarding uranium with thermal neutrons from the 241Am-Be source that has a flux of 5 ×103 n cm-2 s-1. Calculations of the concentration levels were made through comparison with standard samples. The outcomes demonstrated that the minimum uranium value is 0.038 ppm and the maximum uranium value is 0.078 ppm
