The Thermo Scientific RadEye GN Gamma Neutron Pager has a very high neutron sensitivity that exceeds the time-to-time requirements of ANSI 42.32 and IEC 62401. Both RadEye GN and RadEye GN+ pagers incorporate a single highly sensitive scintillation detector equipped with a miniature photo-multiplier to detect very low radiation levels of both gamma and neutron radiation from any source.
Alarm Status Display Settings:
The RadEye GN indicates whether the alarms are due to gamma or neutron by a different colored alarm LED, different tones and flashing the count rate/dose rate display readings with an inverted display background of the alarming channel or both channels as appropriate. The RadEye GN also has different audible alarms, discriminating between elevated background/NORM and any artificial isotope alarm. The gamma and neutron audible alarms are clearly different. This gives the RadEye GN audible and visual identification using NBR of the type of material detected.
A bright orange LED for gamma alarms and a bright blue LED for neutron alarm is viewable from the front and above. When a dual gamma and neutron alarm is detected, both LEDs flash. Both readings on the display are flashed with a reversed background.
