Abstract |
|
Ten representative geological samples were collected from the Southern of Eastern Desert, Egypt, for analysis by instrumental neutron activation analysis as a sensitive nondestructive analytical tool for the determination of twenty of the major, minor and trace elements. The samples were properly prepared together with standard reference material and simultaneously irradiated in a neutron flux of 2×1011 n/cm2s in the Second Egyptian research reactor (ETRR-2) facility. The gamma spectra were collected by an HPGe detector and the analysis was done by means of a computerized multichannel analyzer. Twenty elements were determined from qualitative and quantitative analysis, which were Al, Na, Cl, K, Sc, Ca, Cr, V, Mn, Fe, Co, Ba, La, Ce, Tb, Yb, Lu, Hf, Pa and Np. Elemental concentrations were also checked using EDX technique.
The aim of this research is to use two analytical techniques named Neutron Activation Analysis (NAA) and Energy dispersive X-ray (EDX) to achieve an accurate knowledge about content and determination of the concentration for each element in selected geological samples from southern of eastern desert -Egypt.
