A quantitative comparison of cardiovascular imaging systems with respect to the resolution capabilities and the resulting skin entrance doses operating in both fluoroscopic and cine mode

Creator:: Helms, W. Scott
Abstract:: The increasing use of medical procedures using ionizing radiation has increased significantly in recent years. In 1987, the National Council on Radiation Protection Report 93 (NCRP) reported that the average exposure ionizing radiation was 53mRem/year (0.53mSv/year). In their most recent study on radiation exposures NCRP Report 160 in 2009, the...

Determining the bioavailability of soil-associated radium using in vitro methodology

Creator:: Tack, Krystina M.
Abstract:: Soil that is contaminated with radioactive elements poses an exposure hazard to those whom may take up temporary or permanent residence on such a site. Of particular interest is the internal exposure from ingestion of this radioactive soil. Although most ingestion of soil is inadvertent, usually being attached to foodstuffs...

Validation of radiographic automatic exposure control device testing in the era of filmless radiography : and new variables associated with testing

Creator:: Allman, Robert M.
Abstract:: The exposure needed for a clinically useful image requires much less precision when using digital radiography (DR) than when using screen/film (SF) radiography. The Automatic Exposure Control (AEC) device was developed for ensuring accurate and precise exposures with SF technology. This thesis evaluates the importance of the AEC device in...

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...

Environmental pathway analysis of a radioactive zirconium sand uploading facility

Creator:: Miller, Robert E.
Abstract:: The Teledyne Wah Chang facility is a manufacturer of the rare metal zirconium. The facility has been in constant production since 1956. In 1973 an attempt to utilize different sand ore sources from Nigeria and India in a new carbiding process, prior to chlorination, failed. The resulting byproducts of the...

Release of patients following the administration of radiopharmaceuticals

Creator:: Munger, Eric J.
Abstract:: As a standard practice, the use of radioactive materials has been widely used when treating many diseases. In recent years advances in biotechnology and labeling techniques have broadened the application of these materials. Candidates selected for radiopharmaceutical therapy may be treated on an outpatient basis or hospitalized following administration to...

Use of GIS software to map contaminant distributions and determine integrated dose for purposes of assessing impact to biota

Creator:: Myers, Margaret C.
Abstract:: The objective of this research was to estimate the radiological impact on various non-human biotas by the Fukushima Daiichi Nuclear power plant radiation release resulting from Japan's tsunami in March 2011 consistent with the recent recommendations of the International Commission on Radiological Protection. Soil concentration data given by Japan's Ministry...

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...

Improvements in the dosimetric models of selected benthic organisms

Creator:: Caffrey, Emily Amanda
Abstract:: The International Commission on Radiological Protection (ICRP) has modeled twelve reference animal and plant (RAP) species using simple geometric shapes in Monte–Carlo (MCNP) based simulations. The focus has now shifted to creating voxel phantoms of each RAP to advance the understanding of radiation interactions in nonhuman biota. The work contained...
