Process Optimization in the Chemical Life Cycle of Accelerator-Produced, Low Specific Activity 99Mo

Creator:: Bettinardi, David J.
Abstract:: Global efforts to support non-uranium approaches for 99Mo production, due to the proliferation risks associated with 235U fission-based production methods, have recently taken huge strides towards fruition. Several linear accelerator-based methods are currently in late-stage development that can produce low specific activity 99Mo from enriched 98/100Mo targets. The development of...

Purification of cyclotron-produced 89Zr for its use in diagnostic radiopharmaceutical labeling

Creator:: Knaus, Clinton W.
Abstract:: Production of 89Zr serves as a crucial preliminary step for exploring Zr-chelates, determining their stability constants, and advancing radiolabeling methodologies for monoclonal antibody based theranostics. 89Zr is typically produced by the irradiation of natural yttrium targets, a process extensively documented in scientific literature. Two primary methods are employed: the 89Y(p,n)89Zr...

Investigation of f-Element Extraction and Ligand Association in the ALSEP Extraction System for Used Nuclear Fuel Reprocessing

Creator:: Holfeltz, Vanessa E.
Abstract:: Effective separation of lanthanides (Ln) from the minor actinides (MA) is a crucial technical challenge to closing the nuclear fuel cycle. This separation is a necessary prerequisite to transmute long-lived isotopes of Am and Cm, which will allow a reduction of the repository volume, thermal load, and radiological toxicity of...

Organic Phase Inter-Ligand and Metal-Ligand Speciation in TALSPEAK and ALSEP Solvent Extraction Systems

Creator:: Gullekson, Brian J.
Abstract:: Partitioning of trivalent actinides (in particular, americium and curium) from the fission produced light lanthanides is a major concern of used nuclear fuel reprocessing for the purposes of waste disposal. Several solvent extraction processes have been developed to address these chemically difficult separations. The historically employed TALSPEAK Process utilizes di-2-ethylhexyl...

Radiation Detection Using a Semiconducting Nanocrystal Detector

Creator:: Rinaldi, David William
Abstract:: Nanostructured material has been projected to be the next generation material for the detection of ionizing radiation due to the uniquely superior physical processes associated with charge creation and by virtue of their optoelectronic tunablility. Semiconducting Nanocrystal (NC) detectors, by nature of their low band gap material, low fabrication costs,...

Butterfly Puddling: An Alternative Cs-137 Pathway to the Pale Grass Blue Butterfly Following the Fukushima Nuclear Accident

Creator:: Hermann, David A.
Abstract:: Environmental modeling as a result of the Fukushima accident has been at the forefront for present day health physics. The accident released radionuclides in the environment and the fate and transport of these radionuclides are of interest when considering doses to non-human biota. The Pale Grass Blue Butterfly was studied...

Modeling of an Urban Radiocesium Pathway from Catchment to Wastewater Treatment Sludge

Creator:: Ng, George M. H.
Abstract:: The urban hydrology and hydraulics program, US EPA SWMM 5, has been coupled with a compartment model of a wastewater treatment plant (WWTP) in the system dynamics software, STELLA, to simulate the radiocesium pathway from urban catchment to the wastewater treatment sludge. Two literature case studies were re-examined. Firstly, a...

Development and Application of Voxelized Dosimetric Models for Biota : Characterization of the Uncertainty in the International Commission on Radiological Protection's Wildlife Dosimetry System

Creator:: Caffrey, Emily Amanda
Abstract:: A system for radiological dosimetry for nonhuman biota developed by International Commission on Radiological Protection (ICRP) relies on calculations that utilize the Monte Carlo simulations of simple, ellipsoidal geometries with internal radioactivity distributed homogeneously throughout. In this manner it is quick and easy to estimate whole-body dose rates to biota....

Integrated Spatial and Temporal Stochastic Model in Radiation Biology : Design, Implementation, and Application

Creator:: Liu, Ruirui
Abstract:: Mathematical modeling plays a pivotal role in understanding the mechanism of radiation-induced cellular effects, and also in quantifying the radiation risk to the cell. However, there are still compelling challenges facing the conventional modeling in radiobiology, such as lacking a generalized theory structure of quantifying target effect and non-target effect...
