Abstract

The availability of 238U, 232Th and 40K in sequence of rocks consisting the Agbada Formation in the Niger Delta Basin has enhanced the discrimination of non-reservoir from reservoir rocks by geophysical logging. The overlying Benin Formation, a well-known freshwater source of the three lithostratigraphy of the basin. The radionuclide constituent of groundwater of the Benin Formation and surface water information remained unknown. The health and risk implications of consuming water with significant radionuclides is lethal. Consequently, it is necessary to establish the radionuclide status of aquifers, as groundwater to a large extent and river water to a lesser extent are sources of drinking water in the Niger delta.
