Where can I find documentation, manuals, and demo data?
All documentation — manuals, technical specs, brochures, and demo data — is available at docs.medusa-radiometrics.com. Contact support via email or phone for questions not covered there.
How do I connect to the sensor and start a survey?
Power on the sensor, connect to its Wi-Fi, open mDOS in a browser, wait for GPS lock, and start logging. The full workflow is documented step by step in the mDOS manual.
What power supply do Medusa sensors require?
Medusa sensors require external DC power (9–36V, model-dependent) — no internal battery. They run from a vehicle’s 12V system, drone power output, or a field battery pack.
How is gamma-ray sensing applied in civil engineering?
In civil engineering, gamma-ray surveys map soil variability for roads, railways, levees, and dredging projects — enabling faster, cheaper site investigation compared to conventional drilling.
How is gamma-ray mapping used in mineral exploration?
In mineral exploration, gamma-ray mapping identifies lithological boundaries, alteration zones, and uranium targets. Medusa sensors have been deployed globally for vehicle, drone, and airborne surveys.
What data formats does mDOS export?
mDOS exports CSV, GeoJSON, KML, and raw spectral files. Data is compatible with QGIS, ArcGIS, Excel, and Python for post-processing and map production.
Do I need special training to operate a Medusa sensor?
No specialist training is required. Connect power, join the sensor’s Wi-Fi, and open mDOS in a browser. Full documentation is available online, and Medusa offers training and support.
What is the gSMS-100 and how does it measure soil moisture?
The gSMS-100 is a stationary sensor that measures soil moisture continuously without soil contact, using gamma-ray attenuation. Ideal for irrigation management and long-term monitoring.
How does gamma-ray mapping support precision agriculture?
Gamma-ray mapping enables precision agriculture through soil zone delineation, clay content mapping, smart soil sampling, and yield prediction support — typically using the MS-700 on a vehicle.
Can Medusa sensors be used for contamination mapping?
Yes — contamination mapping is a core Medusa application. Sensors detect Cs-137, uranium/thorium anomalies, and industrial NORM by measuring the full gamma-ray spectrum for radionuclide identification.
How accurate is gamma-ray soil mapping?
Gamma-ray mapping is highly repeatable. Accuracy depends on calibration and soil reference samples. Studies report R² values above 0.85 for clay content when calibrated properly.
How deep does a gamma-ray sensor measure into the soil?
About 90% of the gamma-ray signal comes from the top 30–40 cm of soil. It is a topsoil technique, with effective depth influenced by soil density, moisture, and sensor height.
