Abstract It has been established that radionuclides accumulates during mining and mineral ore processing, leaching into water bodies and thus increases naturally occuring radioactive materials (NORM) concentration levels. In this work, theoretical and experimental methods have been used to study radionuclides transport and fate in groundwater systems at the Newmont Akyem Goldmine in the Eastern Region of Ghana. Radiation doses from radionuclides in groundwater have been modeled by considering advectiondiffusion equation in underground system. A mathematical model using a numerical solution based on the finite difference method has been used to describe the transport processes of radionuclides in the groundwater systems under continuous distraction as a result of mining activities. A code written in Matlab was used to compute the numerical solutions of the advection-diffusion equations using available site specific parameters. The results of the model predict an increasing concentration of radionuclides of the U-Th Series and the potential radiation doses through consumption of groundwater in the study area. The solutions may prove useful for simplified analysis of radionuclide transport in groundwater. Analytical solution was used to verify the results from the numerical model with some experimental data obtained from gamma ray spectroscopy analysis. For experimental verification two sampling zones were earmarked: within 5 kilometers radius and 10 kilometers radius from the mine concession.
