Mapping radionuclide distribution in surface sediments using GIS and an underwater HPGe detector
- Westinghouse Savannah River Company, Aiken, SC (United States)
Gamma-emitting radionuclides in the surface sediments of L Lake were examined in situ with an underwater High Purity Germanium (HPGe) detector and further studied by retrieving various sediment samples for analysis by HPGe gamma spectrometry. The predominant man-made radio nuclide detected was cesium-137. These measurements were part of a four phase strategy for characterizing L Lake contaminants. The radionuclide distribution data provided by these studies can be directly compared to baseline gamma surveys done in 1985 prior to the lake`s completion. All available data were carefully considered in the preparation of an Environmental Impact Statement (EIS) that evaluates the consequences of discontinuing river water pumping to the man-made cooling water reservoirs at the Savannah River Site.
