| Abstract | ||
| The aim of this work is to measure the uranium concentration in male and female children's teeth samples collected from different countries.The uranium concentration in teeth samples were measured by using CR-39 track detector. The nuclear reaction is used as a source of nuclear fission fragments is (n ,f) obtained by the bombardment of 235 U with thermal neutrons with flux (5000 n cm-2s-1 ) from (Am-Be) neutron source. The concentration values were calculated by a comparison with standard samples was which prepared. The obtained results show that the concentration is ranging from (0.3204±0.06 ppm) in Oman for female to (0.1965±0.04 ppm) in UAE for male, the uranium concentration was the highest in Oman for female. | ||
