A Preliminary Investigation of Radionuclide Distribution, Transport and Behavior in the Savannah (Georgia) Estuary

来自佐治亚理工学院的PI将利用MRPG资金研究37Cs在萨凡纳河口的分布、迁移和行为。该项目的目标是确定河口沉积物是否是天然和人为放射性核素的永久汇。将在该河口采集约20个沉积物岩芯，并从附近的河流和海洋环境中采集一些样本，以获得“终点”。将对样品进行37Cs、主要阳离子、痕量金属、矿物学和粒度分析。PI还将分析她的样品中的210Pb、226Ra、234和7Be，以确定影响萨凡纳河口沉积物的主要物理运输过程。

ABSTRACTOCE-0133160A PI from Georgia Institute of Technology will use MRPG funds to study the distribution, transport and behavior of 37Cs in the Savannah Estuary. The goal of this project is to ascertain whether sediments in estuaries are a permanent sink for naturally-occurring and anthropogenic radionuclides. About 20 sediment cores will be collected in this estuary along with some samples from nearby riverine and marine environments to obtain "endpoints". Samples will be analyzed for 37Cs, major cations, trace metals, mineralogy and grain size. The PI also will analyze her samples for 210Pb, 226Ra, 234Th and 7Be to identify the dominant physical transport processes affecting sediments in the Savannah Estuary.
