First responders must quickly identify radioactive material and discriminate between natural and artificial gamma radiation during active search missions. The Thermo Scientific™ RadEye™ NBR (Natural Background Rejection) High Sensitivity Gamma Radiation Monitor discriminates between natural and artifical gamma radiation in seconds. The RadEye NBR detector identifies very small contributions of artificial gamma radiation despite large variations of the natural background during the search. Clear audible and visual alarms indicate radiation instantly even for shielded or remote gamma sources.

The RadEye NBR monitor is a combination of the Thermo Scientific™ RadEye™ SX multi-purpose meter and the Thermo Scientific™ FHZ 674 NBR detector. The RadEye SX monitor is a modern and compact multipurpose survey meter that fits to most any external scintillation detector.

  • The possible presence of artificial radiation is indicated on a 0 to 200 %-scaled bar graph (100% = NBR alarm set point).
  • The audible indication for positive detection of artificial radiation is well distinguished from the typically much more frequent gross gamma alarms that are caused by changing background conditions.
  • Alarm on small traces of artificial gamma radiation.
  • Ideal for detection of shielded sources.
  • Weighs approx. 3 kg.
  • One-hand operation.
