“…Thus the reserve provides a test area dominated by granite, which has high levels of natural radioactivity; granite-rich areas consequently provide interesting radiation characteristics. 15,16 The route started in a light residential zone with tar roads and continued along a dirt track into the nature reserve. The relative potassium, uranium and thorium concentrations are plotted in Figures 3, 4 and 5, respectively.…”

HOW TO CITE:Bezuidenhout J. Testing and implementation of a transportable and robust radio-element mapping system. S Afr J Sci. 2015;111(9/10), Art. #2014-0350, 7 pages. http://dx.doi.org/10. 17159/ sajs.2015/20140350 Gamma ray spectroscopy has been successfully applied as a survey tool in the fields of morphology, geology and mineral exploration. Gamma ray surveys are regularly done at ground level, which frequently requires transecting remote and unforgiving environments. Thus a need for the development of a transportable, robust and portable gamma ray detection system was identified. In addition to collecting radiation data, such a system was required to also provide the geographic position of the data and allow for various analyses tools to be utilised in the field. These functions were achieved by integrating a USB-driven scintillation detector with a field tablet and creating software to control acquisition and analyses of radiation data, as well as logging position. The system was tested in different geographical locations under different modes of transport. The instrument was tested by employing several different methods of data analysis in order to extract natural nuclide condensations. The consistency in the obtained data demonstrated the reliability of the instrument in the different environments. The system also successfully replicated previous radio-element survey findings and provided information on several geographical phenomena, including information on the geology, paved road structure and beach sediment characteristics.

“…The activity (analytical) concentration of thorium, uranium and potassium are converted into elemental concentration in the units of parts per million (PPM) of the granites of North Karnataka region mentioned in Table 5. Locations of collected [27] samples are mentioned in the Table. In the studied area three types of granites viz. younger gneiss complex, older gneiss complex, younger granites are found.…”

The natural radioactivities due to uranium, thorium and potassium in granite samples contribute to the radiation dose received by human beings significantly. It is essential to evaluate the activity levels of these nuclides for the assessment of natural radiation dose. The natural radioactivity levels of some granite samples collected from different quarries of North Karnataka, India are estimated using high-resolution gamma ray spectrometry technique and the results are reported in this paper.

“…Granite has relatively high concentrations of natural radioactive isotopes and the potassium concentrations can even be as high as 5%. 13,14 The soil on Malgaskop therefore also consists of high concentrations of potassium.…”

Saldanha Bay on the west coast of South Africa is surrounded by various nature reserves, military units and training sites. Over a long period of time, large parts of this semi-arid area were exposed to human activities, including military training and the preparation of forces for war. This article investigates the prospect of identifying areas where human activities took place via mapping of the variation in primordial radioactive isotopes. For this purpose, in situ gamma-ray data were obtained from selected locations around Saldanha Bay. The data were used to extract concentrations of primordial radioactive isotopes in these locations. The radioactive primordial isotope concentrations were then mapped and compared to historical evidence of human activities in these areas. The concentrations of potassium isotope showed a relationship to the height above mean sea level. Historical human activities were mainly confined to flatter regions of the area around Saldanha Bay and therefore also relate to the height above mean sea level. The potassium concentrations and the areas where human activities took place were compared and a significant relationship was found.
