What Are UAV Radiometric Services?
UAV radiometry is a method of using a radiometric sensor mounted on a UAV (unmanned aerial vehicle) to collect data about the electromagnetic radiation emitted by the Earth’s surface. This data can be used to create maps and other geospatial products that show the distribution and intensity of the radiation at different locations.
Radiometric Survey Application And Benefit
UAV Radiometric Surveys Have Proven Effective:
Mineral Exploration
Mineral deposits directly (uranium) or indirectly by association (rare earth elements, gold, copper, etc.) via thorium or potassium alterations.
Environmental
investigations to identify the presence of radioactive material. Oil and Gas Exploration – Radiation anomalies exist above most oil and gas reservoirs in the form of radiation “halos” surrounding salt domes.

Industrial
Inspect the integrity of industrial processes, from leak detection to the corrosion of process equipment.
Environmental
Measure radiation levels (including dose rate)
