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 ...
Determination of the photopeak detection efficiency of a HPGe detector, for volume sources, via Monte Carlo simulations
(University of the Western Cape, 2005)
The Environmental Radioactivity Laboratory (ERL) at iThemba LABS undertakes experimental work using a high purity germanium (HPGe) detector for laboratory measurements. In this study the Monte Carlo transport code, MCNPX, ...
