Overview
The Thermo Scientific RadEye NBR (Natural Background Rejection) High Sensitivity Gamma Radiation Monitor is designed for first responders and security professionals to quickly discriminate between natural and artificial gamma radiation in seconds. It identifies very small contributions of artificial gamma radiation despite large variations in natural background during search missions. Features clear audible and visual alarms for instant radiation detection, even for shielded or remote gamma sources. The system combines the RadEye SX multi-purpose meter with the FHZ 674 NBR detector. Weighs approximately 3 kg with one-hand operation capability. Ideal for first responders, fire brigades, security professionals, environmental monitoring, and remediation applications.
