Airborne Radiometrics Acquisition

 The radiometric, or gamma-ray spectrometric method is a geophysical process used to estimate concentrations of the radioelements potassium, uranium and thorium by measuring the gamma-rays which the radioactive isotopes of these elements emit during radioactive decay. Airborne gamma-ray spectrometric surveys estimate the concentrations of the radioelements at the Earth’s surface by measuring the gamma radiation above the ground from low-flying aircraft or helicopters.

Data Acquisition


Primary Processing

Raw data is low resolution and shows banding effects due to daily differences in temperature, humidity, radon, and soil moisture. Our primary processing methods include removal of radon and cosmic background, correcting for temperature and humidity, and normalizing to Thorium. Our Advanced Processing techniques include isolating the Potassium, Uranium, and Thorium (KUTh) channels from the Total Count spectrum. The result is a much higher-resolution image than the standard Total Count Map. This data is then used to generate individual Potassium, Uranium and Thorium Concentrations.
