“…The field radiometric measurements (Table 1) and chemical determination (Table 2), tend to be equal in specific activity and concentrations for massive monzo-syenogranites samples than sheared monzo-syenogranites samples which represent the higher radioactivity concentrations of uranium and thorium if compared with massive monzo-syenogranites samples. This is due to an enrichment that appears to be relevant to the faults, joint, and tension quartz veins [21,22].…”

Wadi El-Nabi' area (῀400km 2 ) constitutes Precambrian intrusive-extrusive complex related to the Egyptian-Nubian Shield (ENS). It includes ophiolitic serpentinites, felsic-mafic metavolcanics (bimodal metavolcanics), metapyroclastics (metatuffs), metagabbro-diorite complex, olivine gabbros, and troctolites (young gabbros), and monzo-syenogranites (younger granites). The field and lab radiometric measurements of radioelements, and their geochemical characteristics were carried out for (15) samples of monzo-syenogranites (55 km 2 ) by RS-230 γ-ray spectroscopy, and HpGe detector. Chemical analyses by ICP-MS are also obtained for the studied granitic rocks to verify the concentrations of specific elements and their inter-relationships with ( 238 U (ppm), 232 Th (ppm), and 40 K (%). Regarding the RS-230 measurements, the of radionuclide concentrations range are (4-6.6 ppm) for eU, (8.7-14.75 ppm) for eTh, and (3.62-5.15%) for K%. On the other hand, the chemical analysis for 238 U, 232 Th (ppm), and 40 K%, of monzo-syenogranites give rise to 3.04 ppm for 238 U, 9.44 ppm for 232 Th, and 1.82 % for 40 K%. The field, and lab radiometric measurements, chemical parameters of P, and D-factors ( 226 Ra/ 238 U, and Uc/Ur respectively) give rise to the disequilibrium state is well evident. On the other hand, the chemical interpretations given by multi-variation diagrams among 238 U, 232 Th, and 40 K, as well as selected elements indicate that the origin of the studied radioactive elements are related to the magmatic process, followed by the later post-magmatic process (hydrothermal).

In the present world, nuclear energy is a must need for various purposes. The main cause of nuclear energy is because of the increasing energy demand, which is not possible to provide by using convenient energy generation. Bangladesh is a lower income country and the energy sector is not so developed here though there is a very high demand for energy. Rooppur Nuclear Power Plant is the only one nuclear generation plant which can provide this kind of huge energy within a very short time. This paper mainly depicts the ins and outs of this plant and discusses it’s feasibility in Bangladesh. It also focuses on the worlds various power generation methods and comprises it with nuclear energy generation. A detailed technical brief is presented in this paper along with advantages, location selection, financial and environmental impacts. This will help researchers to do further researches about nuclear energy in Bangladesh.
