Determination of radon concentration in groundwater of Gadau, Bauchi State, Nigeria and estimation of effective dose

Owing to its proximity to rock and soil, groundwater may contain a non-negligible amount of naturally occurring radioactive materials. If so, the drinking water sourced from deep-bore wells may pose great harm to human health. Acknowledging that water plays a vital role in maintaining a healthy life...
