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…

University Samples More Accurately with Gamma-Ray Spectrometer

How do you increase the accuracy of taking samples in the field? Dutch Wageningen University & Research uses Medusa’s gamma-ray spectrometer to more accurately define its sample locations and thus reducing the risk of false sampling.

Sediment mapping with a gamma ray spectrometer

Underwater mapping of sediments

In recent years, laws and regulations in the field of ecology became more strict due to public pressure. Therefore, the discharge of fines during dredging and land reclamation works and its impact on seafloor habitats is an important aspect in environmental impact assessments.

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 […]

Gamma-Ray spectrometer for exploration and mining

The use of airborne gamma-ray measurements has a long-standing tradition in geophysical research. The airborne measurement of gamma radiation emitted by naturally occurring elements like potassium (40K), thorium (232Th) and uranium (238U) is a common method in exploration.

A rugged gamma-ray spectrometer on a TEM frame

Airborne gamma-ray surveys (GRS) have been routinely applied for decades to map the earth’s surface. Recent advancements in computing power and detection technology have significantly improved and it is now possible for gamma-ray systems to be manufactured more compactly, rugged and light-weight. These next generation gamma ray spectrometers open boundless opportunities to use these systems […]
