RS 801 - Radiometrics Data Processing

The module starts with ratios. Looking at the ratios of radioelements is a useful tool. Many of the factors that affect radioelement concentration are present in all windows, such as soil moisture, vegetation and topography. By taking the ratio of two different radioelements these factors essentially cancel out, leaving a more robust geological signal. Next, the discussion takes you to ternary radioelement maps. After that [...]

The objective to conducting radiometric surveys is to determine and map natural radioactive emanations, called gamma rays, from rocks and soils. All detectable gamma radiation from earth materials come from the natural decay products of only three elements at the surface ground; uranium (U), thorium (Th), and potassium (K). Gamma ray data are inherently noisy due to the statistical nature of radioactive decay.  However, the [...]

Radiometric Surveying is commonly used in mineral exploration for geologic mapping, uranium detection and delineation of various intrusives. The objective to conducting radiometric surveys via airborne spectrometer is to determine and map natural radioactive emanations, called gamma rays, from rocks and soils. All detectable gamma radiation from earth materials come from the natural decay products of only three elements at the surface ground. They are uranium [...]
