Atmospheric Radon Modeling for Aerial Measurements

Creator:: Owensby, Brittany N.
Abstract:: The Ariel Measuring System (AMS) is a national asset in responding to radiological or nuclear events. The AMS operates out of several aerial platforms, such as the BK-117 helicopter and the P3 Long Range Tracker, under many equipment configurations. Measurements can be telemetered real time to reach back for evaluation...

An analysis of the viability of ranked set sample methodologies based on the evaluation of Dyess AFB B-47 crash site radiological contamination survey data and theoretical modifications

Creator:: Miller, Vivien J.
Abstract:: Since Ranked Set Sampling (RSS) was proposed in 1952 by G.A. McIntyre, it has been the subject of many statistical investigations and a large number of field studies. Throughout these studies RSS has been proven to provide a better estimate of population the mean and variance than Simple Random Sampling...

Evaluating the presence of radium-226 in soil surrounding a coal-fired power plant using the multi-agency radiation survey and site investigation manual (MARSSIM)

Creator:: Herring, Thomas A. (Thomas Andrew)
Abstract:: Coal-fired power plants constitute a significant source of energy production for the United States, and are projected to do so for decades to come. Most of the scrutiny coal-fired power plants receive is in the form of environmental concerns regarding green house gas emissions of carbon dioxide, sulfur dioxide, and...
Resource Type:: Masters Thesis

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...

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...

Relative effective dose risk based on medical diagnostic modalities at the Nebraska Medical Center

Creator:: Petrocchi, Michael D.
Abstract:: The use of medical diagnostic imaging involving ionizing radiation has drastically increased in recent years causing concern about possible long term consequences such as the induction of cancer. Recognizing this recent trend, the Institutional Review Board (IRB) at the Nebraska Medical Center commissioned this study in order to determine effective...

Performance validation of a prototype skin contamination detector via use of very thin thermoluminescent dosimetry

Creator:: Kaiser, Krista
Abstract:: The Nuclear Regulatory Commission (NRC) sets regulations for specific depths in the human skin for exposure to highly localized radioactive particles known as hot particles. This research determines the dose rate to a 10 cm² area with a density thickness of 1 mg/cm² at depths representing shallow dose, lens of...

Development of a CZT-Silicon Detection System in Support of the Comprehensive Nuclear-Test-Ban Treaty

Creator:: Alhawsawi, Abdulsalam M.
Abstract:: The Comprehensive Nuclear-Test-Ban Treaty (CTBT) bans all nuclear explosion tests for military or civilian purposes. The International Monitoring System (IMS) was established to verify compliance with the treaty. It consists of several monitoring stations that detect: seismic activities, hydrocoustic activities, infrasound waves, and radionuclide particles and noble gases. Radioxenon detection...

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...
