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...

Understanding the Application and Benefits of Learning-based Methods in Nuclear Science and Engineering

Creator:: Gómez Fernández, Mario Enrique
Abstract:: Known as the fourth industrial revolution, digitization is an ongoing trend in all ﬁelds, in which various industries are integrating information technologies to support and improve their businesses. Nuclear technology industries have also increased their interest in data-driven methods by leveraging the potential of pattern recognition to identify anomalies and...

Comparison between AAPM's TG-21 and TG-51 clinical reference protocols for high-energy photon and electron beams

Creator:: Nes, Elena M.
Abstract:: In radiation therapy it is very important to accurately measure the amount of radiation delivered. The effectiveness of the treatment depends on delivering the dose with an accuracy of 5% or better. The dosimetry in different clinics must also be consistent. For these reasons national and international calibration protocols have...

Implementation of radiation film dosimetry system to be used for the verification of a 3-D electron pencil-beam algorithm on a radiation treatment planning system

Creator:: Jones, Quyen L.
Abstract:: Radiation film dosimetry process using the RIT 113 v.4 dosimetry software and the film digitizer VXR-l2plus was used to evaluate the accuracy of electron dose calculations of the RAHD radiation therapy treatment planning system at Samaritan Regional Cancer Center. Kodak Ready-Pack EDR-2 film is recommended for dose distribution analysis in...

Application of autoradiographic techniques for contaminant distribution studies in soils

Creator:: Povetko, Oleg G.
Abstract:: In order to determine the physical location of contaminants in soil, two solidified soil "thin" sections, which preserve the undisturbed structural characteristics of the original soil, containing weapons-grade plutonium from the Rocky Flats Environmental Test Site were prepared. Two autoradiographic methods were used in radionuclide mapping: contact autoradiography using CR-39®...

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...

Comparison of dosimetric modeling of the International Commission on Radiological Protection trout reference animal

Creator:: Comolli, Michelle LeAnne
Abstract:: Radiation protection has historically been from a human protection approach, therefore many studies have neglected the potential dose contribution from the gastrointestinal tract (GIT) in animal studies. The International Commission on Radiological Protection (ICRP) utilized simplified geometric shapes with Dose Conversion Factors (DCF) based on homogenized models for the trout...

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...

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...

Assessing and evaluating the energy and angular dependence of the Self-indicating Instant Radiation Alert Dosimeter (SIRAD)

Creator:: Bak, Alysse K.
Abstract:: The Self-indicating Instant Radiation Alert Dosimeter, SIRAD™, manufactured by JP Labs*, is a dosimeter that can be used by emergency response persoimel. It is a user-friendly, inexpensive, and disposable radiation dosimeter. It monitors high doses, 5-200 rads, of ionizing radiation. The card resembles the size of a credit card and...
