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.

“…Therefore, the term "biomass" applies to the biomass density of plants, which is mass per unit of living and dead plant content (Nowak et al, 2003;Iwata, 2007;Assefa et al, 2013). By increasing the biomass density in urban areas, there is a high potential for climate change mitigation and air quality improvement through enhancing carbon sequestration (DeFries et al, 2000;Global Forest Resources Assessment, 2020;Strohbach and Haase, 2012;Nyamugama and Kakembo, 2015;Bottalico et al, 2016). How to establish adaptation strategies for biodiversity evaluation and tracking and controlling of carbon is a key focus since these factors are necessary for meeting national climate change commitments.…”
