An investigation on photoneutron production from medical linear accelerators

Creator:: Eller, Leanna R.
Abstract:: The photoneutron production from three Varian linear accelerators ranging in energies from 6 MV to 23 MV has been investigated. Photoneutrons are produced during (γ, n) interactions with materials located within the treatment head. These unwanted neutrons not only increase patient dose, but may also lead to the requirement of...

CFD analysis of pressure differentials in a plate-type fuel assembly

Creator:: Roth, Gable D.
Abstract:: The Hydro-Mechanical Fuel Test Facility (HMFTF) is being built at Oregon State University to evaluate fluid flow through plate-type fuel assemblies. The first plate assembly that will be examined in the facility is the Generic Test Plate Assembly (GTPA). The GTPA consists of an array of six parallel flat plates,...

Dosimetric verification of respiratory gated radiation therapy for tumors involving the lung

Creator:: Webb, Lindsey S.
Abstract:: As the field of radiation therapy evolves new treatment techniques will be established. An example of an evolving treatment technique is respiratory gated radiation therapy (RGRT). Research and studies have shown that RGRT can be used to account for tumor motion as a result of respiratory motion. With evolving technology...

Childhood cancer and spatial analyses of benzene exposure in Texas

Creator:: Roberts, Mark T.
Abstract:: Childhood cancers are rare diseases that affect 188 children in Texas for every million born. Leukemia is the most common childhood cancer and accounts for roughly one third of childhood cancer cases. However, it is estimated that only 10% of childhood cancer cases can be explained by known risk factors....

Penumbra : A Spatiotemporal Shade-Irradiance Analysis Tool with External Model Integration for Landscape Assessment, Habitat Enhancement, and Water Quality Improvement

Creator:: Halama, Jonathan James
Abstract:: Several solar energy models exist, but all models must balance: computational runtime, light complexity, and model output volume. These models span the spectrum of simplistic global solar energy equation sets to complex light ray-tracing models. Spatiotemporally inaccurate representations of solar energy may cause compounding simulation effects and introduce unknown modeling...

Dose-effects relationships in non-human biota : development of field sampling, dosimetric and analytic techniques through a case study of the aquatic snail Campeloma decisum at Chalk River Laboratories

Creator:: Ruedig, Elizabeth B.
Abstract:: In the last decade regulatory bodies have begun to implement standards to protect populations of non-human biota (NHB) from the consequences of radiation exposure. This is a departure from previous regulatory frameworks which were concerned only with protecting man. The implementation of these new standards has started an ongoing discussion...

SSPM-based optical fiber radiation dosimeter

Creator:: Konnoff, Daniel C.
Abstract:: Current state-of-the-art environmental, clinical, and in-vivo radiation sensing systems utilizing various inorganic and tissue-equivalent plastic scintillators are not user friendly, suffer from electron-beam-generated noise, and are difficult to deploy successfully for real-time dosimetry. A robust, real-time detection system using different scintillating materials coupled to solid-state detectors by optical fibers is...

Study of Compton suppression capability in a triple-layer phoswich detector

Creator:: Alhawsawi, Abdulsalam M.
Abstract:: A triple layer phoswich detector was designed and assembled in the advanced radiation instrumentation lab at Oregon State University. The detector had three scintillation layers: the first one was a BC-400 for beta and conversion electron detection, the second layer was a CsI(Tl) for x-ray and gamma detection, and the...

Radiation dose and risk in interventional neuroradiology

Creator:: Magill, Dennise M.
Abstract:: BACKGROUND/PURPOSE: Exposure from medical radiation sources are on the rise in the United States. Often the highest potential source of radiation dose to patients and radiology staff occur during interventional radiology procedures performed using fluoroscopy and digital subtraction angiography (DSA) to provide image guidance in minimally invasive surgical procedures. Several...

How well do American viticultural areas correspond with the soil classes in Oregon's northern Willamette Valley? A question for the wine industry

Creator:: Wood, Douglas T.
Abstract:: The specific geography of individual wine growing regions has long been understood to be a significant factor in predicting both a region’s success in producing high quality grapes, and the resulting demand for wines produced from that region's fruit. In the American wine industry, American Viticultural Areas (AVAs) are increasingly...

Applications of Silicone Wristbands to Improve Personal Chemical Exposure Assessment

Creator:: Dixon, Holly M.
Abstract:: Silicone wristbands are easy-to-wear passive samplers that have been readily adapted into environmental health studies since first reported in 2014. Wristbands can be worn during normal daily activities and sequester a wide range of bioavailable organic chemicals. This dissertation includes a thorough review of silicone wristband technology, as well as...

Spatio-Temporal Analysis and Modeling in the Marine Environment : Humpback Whale Genetic Variability and Seabird Distributions in the Northeastern Pacific Ocean

Creator:: Dick, Dorothy Marie
Abstract:: The rapid decline of marine ecosystems worldwide and the failure of traditional single species management pushed for the development of ecosystem-based conservation measures such as marine protected areas (MPA) to slow the loss of marine biodiversity. One approach to MPA creation advocates targeting marine megafauna (e.g., marine mammals, seabirds, sharks,...

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...

Analysis of Oregon's Domestic Well Testing Act data for use in a sentinel surveillance system for private well contaminants

Creator:: Hoppe, Brenda O.
Abstract:: The Safe Drinking Water Act ensures that public systems provide water that meets health standards. However, no such protection exists for millions of Americans who obtain water from private wells. Concern for safety is warranted as most wells draw from underground aquifers, and studies demonstrate that groundwater is affected by...

West Nile virus : forecasting models for a resurging vector-borne disease in Arizona, U.S.A.

Creator:: Roldan, Josiah Javier
Abstract:: West Nile Virus (WNV), a vector-borne disease continues to be a serious threat to public health in the United States, particularly in the Southwest region. While all the states in the U.S. experienced a decreasing trend of WNV disease in 2010, the state of Arizona experienced a sharp increase from...
