Description
Radioactivity has existed since the beginning of time and is part of our planet Earth. Several studies
have been well documented to monitor natural radioactivity as a source of radiation exposure to
the environment and to human beings. In order to determine the effects of natural radioactivity
in around areas of former uranium mines in the West-Rand area, an investigation of radiation
exposure through ingestion of contaminated water will be carried out. In the present work, focus
will be on Uranium daughter radionuclides; Ra-226 and Rn-222. Measurements will include the use
of Alpha and Gamma spectroscopy to identify radionuclides concentrations, as well as Inductively
Coupled Plasma Mass Spectrometer (ICP-MS) and Radiochemical Neutron Activation Analysis
(RNAA) to analyze the isotopes of interest.
