摘要

Technetium-99 (~(99)Tc), cesium (~(137)Cs and ~(135)Cs), neptunium-237 (~(237)Np) and uranium (~(238)U, ~(235)U, and ~(234)U) are all present to varying extents in legacy nuclear waste, proposed spent nuclear fuel repositories and in potential fuel reprocessing and recycling streams [1-6]. Thus, the selected radionuclides are long-lived risk drivers in the Department of Energy (DOE) complexes and are expected to be mobile and potentially hazardous to human and environmental health. Furthermore, this suite of radionuclides encompasses a broad range of biogeochemical behavior characterized by different sorption mechanisms, redox activity, solubility, overall mobility and bioavailability, and can thus be used to inform the behavior of similar radionuclides. Of the many DOE complexes, the Savannah River Site (SRS; Aiken, South Carolina) is the location of interest as this study is part of a larger DOE EPSCoR (Experimental Program to Stimulate Competitive Research) initiative in South Carolina.
