Main: Radiation monitors: GNOME-2
Hand-held radiation monitor "GNOME-2" booklet (PDF ~ 1,26 Mb)
PURPOSE:
- scanning people, transport vehicles and railway cars that pass the checkpoints in order to prevent potential theft of nuclear and radioactive materials (SNM);
- monitoring of environment radioactive contamination (area, rooms), food products, hold up and leakage of radioactive materials from pipelines and etc.
PRINCIPLE OF OPERATION: detecting SNM X- and gamma-rays in the range 40 to 3000 keV on the natural background, which is measured and taken into account during signal analysis.
COMPONENTS: ssmall-dimension remote detection unit, control unit and a coupling rod (extender).

Additional information:
- The monitor is composed of two units: remote detector and control unit that can be connected directly forming a compact monoblock or with using a 0.5...3 m long rod. This construction allows easily inspecting places, which are difficult for access.
- The monitor is equipped with the audio and digital indication. Whenever the NRM radiation exceeds the alarm threshold, the monitor makes a sound, the tonality of which changes depending on the gamma ray count rate.
- The wide operating temperature range is achieved with automatic compensation of ambient temperature effects.
- The monitor has the automatic battery discharge indication.
- The monitor can be connected to PC via a standard interface.
- The detection unit can turn on 90°.
- There is a capability to apply headphones for sound signals.
The designation in procurement orders and in documentation: "Hand-held radiation monitor "Gnome-2" ÒÌÃÈ81".
