Drone borne gamma-ray measurements can be corrected for height.

How can you use a gamma-ray spectrometer under a drone?

The Medusa gamma-ray spectrometers have become the standard for drone-borne mapping soil and geology. For a successful application of these gamma-ray spectrometers, it is important that the sensor gives absolute values concentrations of the radionuclides in the soil.

Our most recent research paper describes how drone-borne gamma-ray can be corrected for the height of measurement. The article can be downloaded here.

The research work is part of a Phd project at Medusa Radiometrics and University Medical Centre Groningen and is subsidized by the European Regional Development Fund (EFRD 2014–2020).

Towards Drone-borne Gammaray Surveing

Recently we finished a first series of flight tests of our “drone-borne” gamma-ray sensor. To answer to the increasing demand for drone-borne sensing systems, we decided almost a year ago, to start the development of a lightweight and rugged version of our gamma-ray detection systems; the “drone detector”. The aim of the project is to create a low-weight, low power and fully self-contained sensor system fit to be used underneath a “standard” unmanned areal vehicle (UAV). A challenge that – as we found – not only involves a fully new detector design, both in hardware as in software, but also a careful look at the drone specifics as we found out the hard way when our first prototype crashed while flying…

Multi sensor system for farmland in Spain

To increase the (financial) yield of Spanish farmers on low-yielding rainfed soils, a EU LIFE+ project ‘Crops for better soil’ was initiated. The aim was to improve the soil itself by applying several agronomic measures and by better understanding the soil. To this purpose Medusa developed an efficient and effective soil sensing system on a […]
