The Influence Of Long-Term Gamma-Radiation And Initially Dissolved Chemicals On Aqueous Kinetics And Interfacial Processes, Pamela A. Yakabuskie

Electronic Thesis and Dissertation Repository

This thesis presents work focusing on the long-term effect of gamma-radiation on aqueous solution kinetics. Ionizing radiation drives the decomposition of water to form both oxidizing (•OH, O₂, H₂O₂) and reducing (•e_aq⁻, •O₂⁻, •H, H₂) chemical species. Over time, these radiolysis products can react with dissolved solutes and participate in interfacial reactions. This can lead to significant changes in the eventual solution redox condition, and gas phase composition, and in certain cases result in the formation of solid species. Understanding the long-term solution kinetics for radiolysis …
