A PRELIMINARY INVESTIGATION OF THE COASTAL GEORGIA REGION

Understanding the effect of particle adsorption/desorption processes in aquatic sediments provides valuable insight that should be considered when interpreting radiogeochemical data. A preliminary investigation was undertaken to identify locations within the Savannah (Georgia) aquatic system that would serve as future study sites for a detailed examination of radionuclide-particle adsorption/desorption processes in the coastal Georgia region. In this current investigation the Savannah area distribution of naturally occurring (e.g. Pb-210, Ra-226, etc.) and anthropogenic radionuclides (Cs-137) has been examined. Results of gamma analysis indicates that sediment particles in this region are subjected to non-steady state processes (physical and biogeochemical) which serve to deposit and remove radionuclides throughout this region. Ancillary biogeochemical data and geographical characteristics were also examined to gain insight regarding additional factors controlling the radionuclide distribution in this region. These preliminary results will serve as the basis of a more in-depth radiogeochemical investigation of Georgia aquatic sediments.
