Humans can be exposed to radioactive materials released to the ground by processes such as mining and milling of uranium, disposal of radioactive waste in repositories and landfills, or through accidents. This chapter covers practical problems of release of radioactive materials from sources, current practices for the characterization of groundwater transport pathways through the unsaturated and saturated zones, and the ultimate consumption of transported radionuclides by humans. It discusses the underlying principles of groundwater flow, the transport of radioactive materials dissolved or suspended in water, and the interaction and retardation of radionuclides with soil and rock along transport pathways. Finally, the chapter discusses the formulation of mathematical models for these processes and presents simplified analytical techniques for preliminary calculations of groundwater flow, contaminant transport, and doses.

Keywords: groundwater flow; radionuclide transport; mathematical models; repositories; retardation; landfills; contaminant transport; unsaturated zone; saturated zone
