Radiometric (or Airborne Gamma-Ray Spectrometer) Surveys detect and map gamma rays. Gamma rays are natural radioactive emanations from materials in the rocks and soils. All detectable gamma radiation from earth materials come from the natural decay products of either potassium, uranium, or thorium. The gamma ray data are interpreted in combination with other airborne survey data, such as Magnetic Techniques, satellite images and geological and soil maps to map minerals with these radioactive elements, such as magnetite.
