Electron paramagnetic resonance for dosimetry in freshwater aquatic environments
Tzivaki, Margarita (2020-08-01)This thesis explores the feasibility of detection of radiological contamination in aquatic environments through Electron Paramagnetic Resonance (EPR) spectroscopy. Exposure of freshwater ecosystems is possible as a result ... -
Encapsulated source contact dose estimates incorporating secondary electron emission
Cleary, James (2015-04-01)Secondary electron emission generated at the surface of thin material from interaction with gamma rays form a significant component of the surface dose. The intensity of this emission is known to vary with material composition ... -
A generic methodology for the three dimensional display of radiation fields
Chaput, Joseph (2010-04-01)The radiation field visualization options available for engineers, scientists and health physicists have traditionally been based in the 2d realm, with techniques such as the generation of isodose curves. From the perspective ... -
Improving x-ray operator performance using virtual environments
Breitinger, Mark (2021-08-01)There are significant limitations in the training for x-ray operators under current regulatory and operational constraints. Advances in technology now allow for the creation of realistic virtual reality environments, which, ... -
Local dose coefficients for radionuclide contamination in wounds
Galipeau, Natasha (2020-05-01)The objective of this research is to create local dose coefficients for radionuclide contaminated wounds to accompany dose coefficients obtained by Oak Ridge Institute for Science and Education looking at whole body effects ... -
Monte Carlo simulations for the purpose of efficiency curve calibration for the Fastscan whole body counter
Graham, Hannah Robyn (2015-08-01)In order to be able to qualify and quantify radiation exposure in terms of dose, a Fastscan whole body counter must be calibrated correctly. Current calibration methods do not take the full range of body types into ... -
New approaches in training for in situ visualization of ionizing radiation measurements
Chaput, Joseph (2022-08-01)Surveying an environment for sources of ionizing radiation requires the use of measurement tools and skills developed from training in order to understand and analyze measurements. Recent advances in technology allow for ... -
Simulation of in-core dose rates for an offline CANDU reactor
Gilbert, Jordan (2016-04-01)This thesis describes the development of a Monte Carlo simulation to predict the dose rates that will be encountered by a novel robotic inspection system for the pressure tubes of an offline CANDU reactor. Simulations were ... -
Towards low dose retrospective dosimetry on shelled species
Hassan, Amna (2020-08-01)This work investigates calcified tissues of shelled species for retrospective dosimetry using electron paramagnetic resonance (EPR) spectroscopy. To determine applicable samples for low dose studies, shells of crustacean ...
