“…The average value was in the safety recommended limit. These results were comparable with the results obtained from bauxite in Nigeria (189-262 Bq•kg -1 with mean value 222 Bq•kg -1 ) [17]. Furthermore, the absorbed dose rate in air at 1 m above the ground surface was calculated at different sampling points using Equation 3:…”

Natural occurring radionuclides are present in many natural resources. Human activities may enhance concentrations of radionuclides and/or enhance potential exposure to naturally occurring radioactive material (NORM). Industrial residues containing radionuclides have been receiving considerable global attention because of the large amounts of NORM-containing wastes and the potential long-term risks of long-lived radionuclides [1]. They have become concentrated and exposed not only to the environment but also to mine workers. Actually, there are a number of authors who have published papers about radiation hazard assessment resulting from phosphate, oil, or gas production [2]. Although aluminum has been widely used in industry, there are few studies focusing on radiation risk from bauxite or red mud [3]. Table 1 shows the range of radionuclides concentrations in bauxite. The activity concentrations of 238 U and 232 Th were high because 238 U and 232 Th decay series depends on geological composition. O'Connor [4-5] measured natural activity concentrations in bauxite, solid residues, and red mud resulting from alumina production in western Australia. 238 U concentration results were 120-350

“…Several works using INAA were carried out by El-Taher A. and his group to characterise the elemental composition of different geological formation around the desert in Egypt and the Egyptian Red Sea coast. INAA of 25 elements, As, Ba, Ca, Ce, Co, Cr, Cs, Eu, Fe, Hf, K, La, Lu, Mg, Mn, Na, Nd, Rb, Sc, Sm, Th, U, Yb, Zn and Zr, was carried out in quartz collected from the region [14]. Activation of the samples was done in the TRIGA Mainz research reactor and the activated samples were analysed using standard gamma spectrometric method.…”

Varied forms of neutron activation analysis (NAA), due to their high accuracy and reproducibility, are being used in geological studies and in medical application for the determination of concentration of elements down to the trace and ultra-trace level. Concentration of Cs, Sc, Fe, Ta, Co and Eu which may give rise to long-lived activity on neutron irradiation has been determined down to 0.1 ppm in rock samples from 11 geological formation in Karnataka, India, using NAA. NAA has been used by several authors to determine elemental concentration in biological shields, different geological formation around the world, thermal springs, archaeological objects and precious stones. NAA has been successfully employed by different groups to determine the concentration of Al, K,
