Prior studies of groundwater systems have associated increasing salinity and anoxic conditions with increasing radium (Ra) activities in water due to the decreasing effectiveness of Ra removal processes. However, the components of salinity (e.g. Ca vs. Na and SO42- vs. Cl-domina…

The Touissit lead-zinc district consists of several Mississippi Valley-type deposits forming a world-class mining district (>4 million tonnes of contained metals) in northeastern Morocco and adjacent Algeria. This thesis focuses on the petrographic, isotopic, and strontium analy…
A global legacy of radioactively contaminated land exists as a result of nuclear fuel cycle operations. Demonstration of the safe management of the UK nuclear legacy, including contaminated land, is important whilst the long term fate of legacy waste remains uncertain and the UK…
Colloids have the potential to enhance the mobility of radionuclides in a range of scenarios, including legacy spent nuclear fuel storage facilities at sites such as Sellafield, UK. Some of the spent nuclear fuel stored in these facilities has corroded, resulting in the formatio…
Radioactive contaminants, including uranium, strontium-90 and technetium-99 are present at elevated concentrations within groundwaters at several nuclear facilities around the world such as Sellafield (UK), Hanford (USA), Oak Ridge (USA) and Mayak (Russia). In-situ remediation t…
In this work, a self-consistent thermodynamic database for the Mg-Al-Ca-Sr system using the modified quasichemical model has been constructed. The thermodynamic description of the quaternary system was established by combining the thermodynamic descriptions of the constituent bi…
