A microscopic study of the interaction between aliovalent dopants and native defects in group IV oxides : indium and cadmium in ceria and zirconia

Creator:: Zacate, Matthew O.
Abstract:: In order to understand better the defect structure and dynamics associated with lower valent dopants complexed with native defects in group IV oxides, In/Cd perturbed angular correlation spectroscopy was performed in ceria and zirconia. Examining the orientation symmetry axis of defects in ceria single crystals at low temperature has allowed...

An allometric examination of the relationship between radiosensitivity and mass

Creator:: Bytwerk, David Paul
Abstract:: The results of a review of six decades of existing literature for 50% lethal dose data across a range of phyla are presented. The collected 50% lethal dose data is limited to adult organisms subjected to acute doses of gamma radiation. The data collected is examined to determine whether useful...

A study of actinide de-excitation through neutron emission from the deuteron induced fission of ²³⁸U

Creator:: Sprunger, Peter Hayden
Abstract:: The process of de-excitation of the actinides is a very important question in both pure and applied science. In this dissertation the process was studied using the neutrons emitted in coincidence with fission induced by the bombardment of ²³⁸U with 14.85 MeV deuterons. Neutrons can be emitted at multiple stages...

A comparison of compact ionization chamber performance and relative readings

Creator:: Gerber, Ryan L.
Abstract:: The purpose of this study is to investigate the relative performance of compact ionization chambers as it changes based on the speed of detector motion and collection volume. To quantify changes, multiple scans were made with each of a selection of compact chambers and repeated varying detector speed. Each scan...

Patient radiation exposure variability and minimization in mobile, C-arm fluoroscopy

Creator:: Van Wieren, Robert T.
Abstract:: BACKGROUND: The frequency of C-arm fluoroscopy procedures is increasing and it has become prudent to increase the awareness of patient radiation exposure to minimize patient risk. There is a strong potential for variability in patient exposure levels and a need for minimizing unnecessary exposure. The variability in C-arm fluoroscopy can...

Prototyping a triple-layer phoswich detection system

Creator:: Duncan, Christopher L.
Abstract:: Multi-layer optically coupled scintillation based radiation detectors, known as phoswich detectors, have rapidly evolved in recent years. During the same time, digital signal processing has improved radiation discrimination accuracy and enhanced reliability, while reducing complexity and size of traditional analog signal processing methods. A new generation of high-speed radiation detectors...

Investigation of a hybrid quasi-diffusion/Monte Carlo method for solving multigroup criticality problems in slab geometry

Creator:: Robinson, Bethany R.
Abstract:: A hybrid Quasi-diffusion/Monte Carlo Method for solving multigroup criticality problems in slab geometry was investigated. Analog Monte Carlo was used to calculate functionals (Eddington Factors) that were then used in solution of the quasi-diffusion equations. The hybrid method was shown to accurately and precisely predict the k-eigenvalue and fission source...

How clean is coal : coal power plant ash pond regulations compared to nuclear reactor decommissioning standards

Creator:: Williams, Manuel P.
Abstract:: Coal power is the prominent source of energy in the United States (U.S.) and around the world. The byproducts of coal power contain many of the same radioactive nuclides that are found in the local environment just in higher concentrations. With so much of this ash being stockpiled, the amount...

Predicting antineutrino source terms from a high temperature gas reactor

Creator:: Shaughnessy, Andra L.
Abstract:: Since the 1990s, researchers around the world have been creating antineutrino detectors for monitoring power reactors. These detectors have been deployed at light water reactors and are able to determine power levels and burn up throughout a fuel cycle. This technology could allow the IAEA to monitor LWRs remotely and...

Design, construction, and characterization of a neutron depth profiling facility at the Oregon State University TRIGA® reactor with an advanced digital spectroscopy system

Creator:: Robinson, Joshua A.
Abstract:: In this work, Neutron Depth Profiling (NDP) analysis capability has been added to the Oregon State University TRIGA® Reactor Prompt Gamma Neutron Activation Analysis Facility (PGNAA). This system has been implemented with an advanced digital spectroscopy system and is capable of rise time pulse shape analysis as well as coincidence...
