Radiometric study of soil: the systematic effects
(University of the Western Cape, 2007)
The natural 238U, 232Th and 40K radioactive content of vineyard soil was measured with an in-situ gamma-ray detector. The activity concentrations measured with the in-situ detector are normalized using the laboratory-determined ...
Determination of natural radioactivity concentrations in soil: a comparative study of Windows and Full Spectrum Analysis
(University of the Western Cape, 2004)
In this study, two methods of analysing activity concentrations of natural radionuclides (U, Th and K) in soil are critically compared. These are the Window Analysis (WA) and Full Spectrum Analysis (FSA). In the usual WA ...
Radon in the Cango Caves
(University of the Western Cape, 2005)
Radon is a naturally occurring radioactive element in the 238U decay series that is found in high concentrations in certain geological formations such as Caves. Exposure to high concentrations of radon has been positively ...
Computational modelling of a hot-wire chemical vapour deposition reactor chamber
(University of Western Cape, 2020)
In this thesis, I explore the subjects of fluid dynamics and the Hot-Wire Chemical Vapour Deposition (HWCVD) process. HWCVD, in its simplicity, is one of the more powerful and elegant deposition techniques available in ...
