… Abstract: A survey of natural radioactivity has been carried out to estimate the
concentration of naturally occurring radionuclides and radiological risk associated in the
south East mining region, which present high natural background radiation. An in-situ
gamma-ray spectrometer was used to map … In addition, we report the results of the utility
of inferential statistical, principal component analysis and a supervised support vector
machine learning for accurate fingerprinting of naturally occurring radionuclides sources …
