Abstract : المستخلص انجليزي The neutron activation analysis technique is used for elemental analysis of some Saudi Ores samples ( Gold and Aluminum ores) . The study depends on the identification and the analysis of the delayed gamma – ray which emit as a result of the thermal neutrons capture by the nuclei of the elements of the investigated sample referring to the half- lives of the radiative istopes in samples. The details of this thesis are included in five chapter: The first chapter is an introduction dealing with the analysis techniques especially (NAA ) which used in this work , a literature review, some ideas about the ( n,γ) reaction , neutron source , neutron energies , gamma-ray and gamma –ray detection . finally the aim of the present work is given Chapter two gives a review of the theoretical principles and limitation related to the technique used . Chapter three describes the experimental system ( the irradiation cell ,gamma-ray detection) and gives a brief account on the electronic equipment which used to analyze the investigated samples energy calibration line construction , thermal neutron , flux calculation and the samples preparation are prescuted . Chapter four , presents the results obtained of qualitative analysis of the samples under investigation ,where (10) elements for gold ore and (12) elements for Aluminum ore are identified from the obtained delayef gamma-ray spectra. Chapter five presents the results obtained the quantitative analysis of gold ore . two methods are used to calculate the concentration of cold element in the ore . In conclusion of this thesis , the experimental results obtained using (NAA) technique and their importance are given .
