Abstract
This work investigates the activity concentration of 238U, the ambient gamma absorbed dose rates (DR), and the 222Rn concentration levels in ground and surface water samples from gold and lead mining area of Moro, Kwara State, Nigeria. In situ measurements of activity concentration of 238U and DR were carried out using Super SPEC RS-125 gamma spectrometer and 222Rn activity concentration in ground and surface waters were analysed using a calibrated RAD7 big bottle system. The results show that the risk of radiation exposure at the mining area is high and the public are not safe from exposure to ionizing radiation.
