Airborne gamma-ray spectrometry is an effective geological mapping tool in many different environments and has been applied to mineral, environmental, geothermal, hydrocarbon and even water investigations. Some of the most common applications for airborne gamma-ray spectrometry surveys include:
- Mineral exploration: gold, mineral sands, uranium, rare earth elements.
- Geothermal exploration: potassic alteration.
- Hydrocarbon exploration: potassic/uranium alteration.
- Geological mapping: mineral, engineering and water exploration applications, paleodrainage systems.
- Contamination mapping and detection: military and industrial waste (e.g. 137 Cs and 60 Co).
- Emergency response: fallout, nuclear contamination.
- Baseline surveys: for mining, nuclear reactor and industrial sites.
- Identification of radon prone areas: to identify areas where residents may be at risk to exposure to high levels of radon gas.
Gamma-ray spectrometric surveys can be flown in conjunction with other Fugro airborne instruments such as electromagnetic, magnetic or gravity systems. The crystal detector volume is determined by the pay-load capacity of the particular aircraft or helicopter used.
