Abstract
Geothermal energy is created by the heat within the Earth. The analysis of granite rock samples was carried out to determine the concentrations in part per million (ppm) by gamma ray spectroscopy using a well calibrated NaI(Tl) detector system, distribution and the potential of Radiogenic Heat Production of some heavy elements in rock samples in Abuja, Federal Capital Territory, Nigeria within latitudes 8°25´N to 9°20´N and longitudes 6°45´E to 7°39´E were evaluated. The distribution of K, U, and Th was principally investigated in this study area where granite rock samples were collected from forty (40) locations in the area. The analysis of the granite rock samples using a well calibrated NaI(Tl) detector reveals the contents and the distribution of the radioactive elements. The results also show that the contribution and rate of heat production of 40 K, 238 U and 232 Th in the samples vary significantly with geological locations using a standard equation, with 238 U as the major element which predominates in heat production in the study area, with 232 Th also contributing significantly while 40K is a trace elements. The radiogenic heat production elements (RHPE) contribution shows that all the points on the sites have the same pattern of radiogenic heat production contribution of the elements to the radiogenic heat production (RHP).
