Radionuclide sorption and desorption reactions with interbed materials from the Columbia River basalt formation

Creators

Description

The sorption and desorption behavior of radionuclides in groundwater-interbed systems of the Columbia River basalt formation was investigated. Radionuclides chosen for study were those of concern in assessing the safety of a high-level radioactive waste repository in basalt (isotopes of technetium, neptunium, plutonium, uranium, americium, cesium, strontium, and radium). Sandstone and tuff materials from selected interbed layers between basalt flows were used in these experiments. Effects of groundwater composition and redox potential (Eh) on radionuclide sorption and desorption on the geologic solids were studied. Sorption and desorption isotherms were obtained for sorption of radionuclides under oxidizing and reducing conditions. The Freundlich equation accurately describes most of these isotherms. 10 refs., 4 figs., 7 tabs
