Instrumental neutron activation analysis techniques (INAA) were applied for elemental analysis of soil samples collected from Toshki area 280 km from Aswan city in Upper Egypt. The samples were irradiated with thermal neutrons at the TRIGA Mainz research reactor. Gamma-ray spectra were recorded using a HPGe detector to determine the contents of major, minor and trace elements in these samples. As a result of the analysis, altogether 32 elements were identified qualitatively and quantitatively. These elements are: Na, Mg, Al, Cl, K, Sc, Ca, Cr, Ti, V, Mn, Fe , Co, Zn, Rb , Zr, As, Nb, Sn, Ba, Cs, La, Ce, Nd, Eu, Sm,Yb, Lu, Hf, Ta, Th and U. In several cases, X-ray fluorescence analysis (XRF) was used for comparison. Furthermore delayed neutron activation analysis (DNAA) was used to determine the uranium content from these samples. The results from different analysis techniques will be compared and discussed.
