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.

UAV radiometry is often used for environmental monitoring and mapping, particularly for applications such as monitoring vegetation health and mapping soil moisture. By measuring the radiation emitted by the Earth’s surface, it is possible to obtain information about the biological and physical properties of the environment. UAV radiometry can also be used for other applications such as mining exploration and mapping, and monitoring of water quality. One of the main benefits of UAV radiometry is that it allows data to be collected quickly and efficiently over large areas. It is also relatively inexpensive compared to other methods of collecting radiometric data. However, the accuracy of UAV radiometry is generally lower than other methods such as ground-based radiometry or satellite-based radiometry.

Radiometric Survey Application And Benefit

Austhai are able to Provide D230A Gamma Ray Spectrometer systems mounted on DJI300 drones for Radiometric surveys in relatively open terrain.

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.


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.

Inspect the integrity of industrial processes, from leak detection to the corrosion of process equipment.


Measure radiation levels (including dose rate)
