Improving x-ray operator performance using virtual environments
(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, ...
Study of contaminants in plasmas during decommissioning processes
(2020-12-01)
With the intention of eventual development of on-site radionuclide capture technologies, methods to simulate radionuclide behaviour when contaminated components are subjected to plasma-based decommissioning processes are ...
Towards low dose retrospective dosimetry on shelled species
(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 ...
Analysis and optimal planning of nuclear-renewable hybrid energy systems for ships
(2021-06-01)
Ocean-going ships are one of the sources of global GHG emissions. Several actions are being taken to reduce the GHG emissions from maritime vessels, and integration of Renewable Energy Sources (RESs) is one of them. Due ...
Local dose coefficients for radionuclide contamination in wounds
(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 ...
Detector integration of severe accident management instrumentation for robotic applications at nuclear reactor facilities
(2021-08-01)
In the aftermath of a nuclear accident, robots can be used to monitor and assess radiological contamination, preventing harmful exposure to plant personnel. In this work, several detectors were evaluated to be supplemented ...
Study of radio frequency inductively coupled thermal plasma torch (RF ICPT) for radioactive waste treatment: thermoplastics - polyethylene and polyvinyl chloride (PVC)
(2021-06-01)
Despite advancements in technology and many progresses made in effort for radioactive waste (RW) treatment and overall management, there is still no final and ever lasting solution. Among the many RW materials originating ...
The influence of surface tension on F2-Bubble Morphology at detachment from carbon electrodes in KF-2HF molten fluoride salt
(2020-04-01)
Molecular F2 and H2-bubbles were generated electrochemically on amorphous carbon electrodes in KF-2HF molten salt to study the effect of surface tension (ϒ) on the profile of a bubble. F2 is used for the purification and ...
Electron paramagnetic resonance for dosimetry in freshwater aquatic environments
(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 ...
Retrospective assessment of human exposures to low dose ionizing radiation using Electron Paramagnetic Resonance (EPR) dosimetry with tooth enamel
(2022-04-01)
This study collected the extracted teeth from people of different ages in the Durham region and analyzed them using the X-band CW EPR spectroscopy. The total dose rate from the natural and anthropogenic sources was 1.9721 ...
