Abstract:
This study proved a relationship between levels of natural radioactivity concentrations and element concentration (ppm) in tooth samples with the ethnic groups using high purity germanium (HPGe) detector and X-ray fluorescence spectrometers (XRF), respectively. The evaluations have been done for 60 tooth samples for different ethnic groups (Kurd, Arab, Turkman, Persian, and Christian" Chaldean Catholic") of the population living in Erbil- Iraq. The results indicated that the high and low levels of radionuclide concentration in teeth samples found in ethnic groups (Turkman and Christan), and (Kurd, Arab, and Persia), respectively. The level of element contents (Na, Ar, Kr, As, Ti, Pt, Eu, Dy, and Pm) was high in teeth samples of Turkman and Christan and zero in teeth samples of Kurd, Arab, and Persia. Response of ethnic groups of Turkman and Christain was similar each to other. Responses of Kurd, Arab, and Persia ethnic groups was similar with each other regarding the XRF results.
