Testing Continuity between Versions 5.3.9 and 6.3.1 of Plaque Simulator for Planning Eye Plaque Brachytherapy Cases

Creator:: Polsdofer, Elizabeth M.
Abstract:: The purpose of this study is to examine the challenges of accepting and commissioning a new treatment planning system for eye plaque brachytherapy. Currently Oregon Health and Science University (OHSU) utilizes v5.3.9 of the Plaque Simulator software to plan all of its eye plaque brachytherapy cases. However, v5.3.9 is no...

Argon-41 production by the OSU TRIGA III reactor

Creator:: Meck, Robert Allen
Abstract:: A sensitive ion chamber-electrometer system was used to determine the Oregon State University TRIGA III reactor's ⁴¹Ar production rate as a function of steady state reactor power and production of ⁴¹Ar due to reactivity pulses up to $3.00. The relative contributions of the argon duct effluent and the pneumatic transfer...

Monte Carlo derived absorbed fractions in a voxelized model of a rainbow trout

Creator:: Hess, Catherine A.
Abstract:: The International Commission on Radiological Protection (ICRP) has modeled twelve reference animals and plants (RAPs) with simple geometric shapes to be used when estimating radiation dose to non-human biota (NHB). In recent years, there has been interest in creating more realistic models in order to better understand the radiation interactions...

A study of state and federal radioisotope licensing requirements

Creator:: Hess, David Owen
Abstract:: At the time of this study 19 states have entered into agreements, one state agreement is pending and one state has submitted its proposal for entering into an agreement with the Atomic Energy Commission for the purpose of assuming regulatory authority over (1) byproduct, (2) source and (3) special nuclear...

Monte Carlo uncertainty reliability and isotope production calculations for a fast reactor

Creator:: Miles, Todd L.
Abstract:: With the advent of more powerful, less expensive computing resources, more and more attention is being given to Monte Carlo techniques in design application. In many circles, stochastic solutions are considered the next best thing to experimental data. Statistical uncertainties in Monte Carlo calculations are typically determined by the first...

Resource Type:: Masters Thesis

An investigation of radioactively contaminated wastewater reclamation plant biosolids

Creator:: Brannan, C. Thomas
Abstract:: Within the last 15 years, wastewater treatment plants have increasingly begun to find radioactive isotopes incorporated in biosolids. Regulations concerning the disposal of radioactive material via sanitary sewer systems were in place since the early 1960's and recently were further restricted. However, the updated regulations would not have prevented certain...

Single and multiple rates of nonequilibrium diffusive mass transfer at the laboratory, field, and regional scales in the Culebra Member of the Rustler Formation, New Mexico

Creator:: Fleming, Sean W.
Resource Type:: Masters Thesis

A web-based medical radionuclide database

Creator:: Jue, Tracy M.
Abstract:: Currently the Food and Drug Administration publishes radiopharmaceutical information for physicians to choose appropriate medical diagnosis and therapy for their patients. The primary functions of these radiopharmaceuticals are diagnosis and delivering doses to a patient with appropriate energy, biological half life, chemical behavior, and radiological half life. These radiopharmaceuticals preferentially...

An investigation of chitosan for sorption of radionuclides

Creator:: Holfeltz, Vanessa Elaine
Abstract:: Chitosan is a biopolymer resulting from the deacetylation of chitin, the second most abundant biopolymer in nature. Chitosan has been successfully used in systems to remove metal ions and other pollutants from wastewater. Chitosan has shown promise as a sorbent for radionuclides in some aqueous waste streams. The sorption of...
