About

Origins and applications
Gamma-ray sensing for geophysical applications developed as a method in the mid-20th century and gained momentum in the second half of the last century, when researchers demonstrated that natural radioactivity could be used to study soil and rock properties. Since then, it has become a well-established technique in mineral exploration, soil texture mapping, precision agriculture and contamination mapping.

The MS-system
The MS series is Medusa Radiometrics’ family of field-ready gamma-ray sensors, built around the embedded Medusa Detector Operating System (mDOS application) and robust hardware. Designed for demanding environments, each unit operates fully autonomously and requires only a power supply to start measuring.
“A sensor built for the field, designed for ease of use and engineered for endurance.”
