"Airborne gamma-ray spectrometry provides measurements of the surface concentrations of potassium (K), equivalent uranium (eU) and equivalent thorium (eTh). The resulting radiometric maps present intricate spatial variations that are controlled among other things by the complex surface processes and the inherent statistical fluctuations of radioactive decays. To enhance the readability of the radiometric images, radiometric domains, spatially-restricted areas presenting a distinctive signature, can be traced to provide local baselines of the surface concentrations of the natural radio elements. This approach was applied to airborne gamma-ray survey data from the “Eastern Athabasca Basin” survey, in Saskatchewan. Ground spectrometry measurements were conducted in 2013 within the radiometric domains that were identified and compare well with domain averages calculated from the airborne survey data"--Abstract.
