Description
This study is aimed at establishing the radiogenic heat production in the Benin Formation of Dahomey Basin using
in-situ measurements of elemental concentrations of uranium, thorium and potassium over a kaolin deposits in
Ifonyintedo, Ipokia LGA, Ogun State. Super-Spec gamma ray spectrometer is used to obtain varied data of naturally
occurring radionuclides over eleven different stations in the Coastal Plain Sands at 1 m height above the ground.
The mean heat produced by uranium, thorium and potassium are 294.3, 410.5 and 0.001 rW kg�1 respectively.
The total heat produced in the study area varied from 544.0 to 902.1 rW kg�1, which classified the study area as
Low-to-Moderate Heat Production Potential zone. This classification corresponds to the radiogenic heat
characteristics of Benin Formation in Niger Delta.
� In-situ measurements of three radioisotopes were made over Coastal Plain Sands of Dahomey Basin.
� The mean heat produced by uranium, thorium, potassium and the total radiogenic heat are 294.3, 410.5, 0.001
and 704.79 rW kg�1 respectively.
� The study area is characterized by Low-to-Moderate Heat Production Potential.
