Radiation dose assessment : measurement, estimation and interpretation
… are often accompanied with additional radiation dose yet this can be justified through the consideration of the benefit it brings. Examples include the use of CT colonography instead of double contrast barium enemas, CT urography replacing intravenous urography and, in nuclear medicine imaging …

Characterization of Radiation Fields and Dose Assessment From Fuels Manufacturing For Advanced Fuel Cycles
<p>The challenge of estimating the radiation dose received by a worker is a complex task. This study was done to examine radiological hazards introduced to workers from the fabrication of fuels with minor actinides (MA) and reprocessed uranium (RepU). Of particular concern is the increase in gamma …

Polonium-210 in Freshwater Environments: Analytical Advances, Predictive Modelling, Food Web Transfer and Dose Assessment
… ²¹⁰Po uptake in Canadian radioecological risk assessments. Finally, dose assessments showed that benthic invertebrates experienced the highest internal exposures, while fish viscera disproportionately contributed to whole-body dose burdens. Collectively, this work provides new tools, empirical …

An investigation into Manganese(2+) interferences and retrospective dose assessment of shelled species using EPR spectroscopy
… tissues of shells are known to impact the lower dose detection limit in retrospective electron paramagnetic resonance (EPR) studies. This thesis investigates the factors causing Mn²⁺ accumulation in shells including crystalline structure and animal habitat. Inductively coupled plasma - optical …
