All Theses
A rapid radiochemical method for the concentration and subsequent analysis of radionuclides from large volume aqueous samples has been developed by using solvent extraction (SX) followed by quantification via liquid scintillation counting (LSC). This was accomplished using simple radiochemical techniques that resulted in the ability to enact a 200x concentration factor and rapidly detect whether radionuclides are present in dilute aqueous samples. The proposed method has average Minimum Detectable Concentrations (MDC) for 238Pu and 233U of 3.5x10-2 Bq/L and 0.16 Bq/L, which equates to 2.3x10-16 and 2.0x10-12 mol/L, respectively. The MDC value for plutonium is an order of magnitude lower …
