Abstract:
Radioactivity and major oxides investigations on lithological rock samples were studied using HPGe and XRF to understand the geological provenience on subsurface structures at Dei-Dei and Kubwa area of Abuja. The activity concentrations at Dei-Dei borehole varies from 18.5 � 1.7 to 37.1 � 3.6 Bq kg‒1, 44.6 � 4.1 to 97.4 � 8.1 Bq kg‒1 and 253.5 � 31.3 to 1195.6 �151.2 Bq kg‒1 for 238U, 232Th and 40K. Kubwa lithologic layers activity concentrations for 238U, 232Th and 40K ranges between 14.7 � 1.2 to 51.8 � 4.9 Bq kg‒, 32.5 � 4.1 to 85.3 � 8.1 Bq kg‒ and 118.9 � 15.7 to 751.2 � 93.9 Bq kg‒1. XRF results revealed that the increase in of 232Th activity decreases the activity of 238U in the presence of SiO2, CaO, Al2O3, Na2O, and K2O. This study provides useful information on the lithology radioactivity and for radiological mapping of the basement coastal pollution
