Development And Application Of Novel Detection Methods For Aqueous Radioactive Iodine, Kelly Grogan

All Dissertations

Novel detection and analysis methods for radioactive iodine concentration and speciation were investigated for aqueous samples. Radioactive iodine is one of the primary risk-drivers at nuclear waste facilities, and regulations for the presence of radioactive iodine in drinking water are stringent. The first phase of this investigation described the development and characterization of a scintillating anion-exchange resin preferential for aqueous iodine in the form of iodide (I-). The resin was incorporated into a radiochromatography flow-cell scintillation detection system that allowed for simultaneous separation, concentration, and detection of aqueous 129I. The performance of this analytical method was characterized with both on-line …
