  • Determination of natural radioactivity concentrations in soil: a comparative study of Windows and Full Spectrum Analysis 

    Maphoto, Katse Piet (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 

    Damon, Raphael Wesley (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, ...

  • Radiometric study of soil: the systematic effects 

    Joseph, Angelo Daniel (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 ...

  • Radon exhalation of building materials 

    Wentzel, Farrel Sidney (University of the Western Cape, 2018)
    Public concern about all radiation and radon exhalation from building materials has been highlighted recently. The purpose of this study is to address this public concern and to investigate the contribution of building ...

  • Radon in the Cango Caves 

    Nemangwele, Fhulufhelo (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 ...
