RayMon10 rugged in-field gamma-ray detector

Hand-held device to search for and identify nuclear isotopes for in-field or lab use

RayMon10 rugged CZT-based isotope detector

A powerful and rugged handheld device for high-resolution Isotope ID.

The RayMon10 is one of the most powerful and rugged handheld radiation monitors in the world. It can be used to detect, measure and accurately identify gamma-ray emitting radionuclides, providing high-resolution isotope identification using the latest CZT solid-state detector technology.

Types of reports include date/time, user handheld ID, photo and audio note, GPS positioning, radiation spectra and isotope identification.

Variations in normal operating conditions can often affect the performance of radio-isotope identification, the RayMon10’s advanced 10 cubic centimetres CZT coplanar grid detector provides more stable performance than scintillation-type detectors.
