Medusa Radiometrics

What Medusa Radiometrics does

Medusa Radiometrics BV is a privately held Dutch instrumentation company headquartered in Groningen that designs and manufactures gamma-ray spectroscopy sensors and supporting software for geophysical applications. The company's product portfolio comprises six spectrometer models (MS-350, MS-700, MS-1000, MS-2000, MS-4000) sized for handheld, drone, vehicle, and airborne deployment, plus the gSMS-100 stationary soil-moisture sensor and the RhoC5 portable density-and-moisture device. Core technology is based on CsI scintillation crystals detecting naturally occurring radionuclides (potassium, uranium, thorium) in soil, sediment, and minerals, augmented by a proprietary Full Spectrum Analysis (FSA) algorithm that separates radon from uranium signals without an upward-looking detector. The company operates an integrated hardware-software ecosystem: the mDOS field operating system for real-time survey data collection and the Gamman post-processing suite for spectral analysis and map generation, plus the mDOS Parser tool for data conversion.

The company sells primarily through direct sales to professional buyers in mining and mineral exploration, agriculture and soil science, environmental contamination mapping, and nuclear research and safety. Revenue is generated from hardware unit sales, software licenses, calibration services, and consultancy through its wholly owned subsidiary Medusa Geoservices. Pricing is quote-based with no public disclosure. Marketing is technical and B2B, relying on documentation portals, scientific publications with academic partners (notably Aarhus University), and industry conferences.

Recent strategic activity centers on the ARGOS next-generation platform, co-funded by the EU Just Transition Fund, which replaces CsI crystals with plastic scintillators interpreted by machine learning to mitigate supply-chain risk and broaden the addressable use cases into emergency response and climate adaptation. The company also deepened ecosystem reach via a partnership with Seequent to integrate Medusa data into the Oasis montaj geophysics platform. The firm employs approximately 10 people, operates without disclosed outside investment, and has been active for over 25 years.

Core offering

Medusa Radiometrics designs, manufactures, and sells gamma-ray survey sensors (MS-350, MS-700, MS-1000, MS-2000, MS-4000, and gSMS-100) for soil, sediment, and mineral composition mapping, deployable on drones, aircraft, ATVs, or as handheld units. The hardware is paired with the proprietary mDOS field operating software and Gamman post-processing suite, which together enable real-time data collection, spectral analysis, and Full Spectrum Analysis (FSA) for accurate natural radionuclide (K, U, Th) mapping. Complementary offerings include the RhoC5 portable density/moisture sensor, mDOS Parser data-conversion tool, calibration services, and consulting via Medusa Geoservices.

Product overview

Medusa Radiometrics specializes in gamma-ray survey sensors and associated software for geophysical applications. Their product portfolio consists of six gamma-ray spectrometer models (MS-350, MS-700, MS-1000, MS-2000, MS-4000, gSMS-100) ranging from compact lightweight sensors for drone deployment to maximum-performance systems for detailed mineral exploration. The ecosystem is supported by two proprietary software platforms: mDOS (Medusa Detector Operating System) for field data collection and real-time monitoring, and Gamman for post-processing spectral analysis including Full Spectrum Analysis (FSA) and elevation corrections. An additional product line includes the RhoC5, a portable soil density and moisture measurement device combining gamma-ray, capacitive, and radar technologies. The company is developing ARGOS, a next-generation system using plastic scintillation crystals with AI-driven analysis to reduce dependence on traditional scintillation materials.
