Product details

Product Info

The Medusa MS-350 is a compact, high-sensitivity gamma-ray spectrometer engineered for aerial, ground, and vehicle-based surveying. Its NaI(Tl) scintillation detector measures the gamma-ray emissions of Potassium (K), Uranium (U), Thorium (Th), and Cesium-137, enabling reliable soil composition profiling, mineral exploration, environmental baseline studies, and contamination mapping. The system supports georeferenced radiometric data capture when paired with a drone GNSS/flight controller, allowing fast, repeatable survey missions.

The MS-350 integrates easily with UAVs such as the DJI M300/M350 RTK, using a supplied mounting bracket and power/data cabling. Data is processed through the included Medusa Gamman software, which performs spectral calibration, isotope concentration analysis, and contour map output. The kit ships with all core hardware necessary for airborne deployment, packaged in a rugged transit case for field operations.

Key features

1. High-Sensitivity Gamma Detection – NaI(Tl) scintillator provides accurate, stable isotope measurement for environmental and mineral surveys.

2. UAV-Ready Architecture – Pre-configured for DJI Matrice 300/350 RTK; additional mounting options available for other drone platforms.

3. Georeferenced Radiometric Mapping – Integrates with GNSS and flight logs to produce spatially accurate radiation and soil composition maps.

4. Professional Data Processing Workflow – Comes with Medusa Gamman software for spectrum analysis, isotope extraction, and GIS export.
