Modelling and measurement of radon diffusion through soil for application on mine tailings dam
(University of the Western Cape, 2004)
Radon has been identified as an important factor that could result in a health hazard by studies all around the world. The health risks can be minimised by preventive measures where radon is highly concentrated as in some ...
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 ...
A comparison of SAAS and chemical monitoring of the rivers of the Lesotho Highlands Water Project
(University of the Western Cape, 2004)
The Lesotho Highlands Development Authority routinely uses the South African Scoring System version 4 (SASS4) in conjunction with water chemistry to monitor water quality of rivers in the Lesotho Highlands Water Project ...
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, ...
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 ...
Monitoring of heavy metals in the Bottelary River using Typha capensis and Phragmites australis
(University of the Western Cape, 2005)
The aim of this study was to use plants to determine the degree of heavy metal contamination in water and sediments in order to effectively monitor and provide possible recommendation to improve the water quality in the ...
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 ...
