  HAND-HELD RADIATION MONITOR "GNOME-5"
 

hand-held radiation monitor Gnome-5 Hand-held radiation monitor "GNOME-5" booklet (PDF ~ 1,27 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) that emit neutrons;
  • monitoring of environment radioactive contamination (area, rooms), food products, hold up and leakage of radioactive materials from pipelines and etc.

PRINCIPLE OF OPERATION: detecting neutron radiation of NRM on the natural background, which is measured and taken into account during signal analysis.

COMPONENTS: small-dimension remote detection unit, control unit and a coupling rod (extender).

 

SPECIFICATIONS
 
Detection threshold at scanning speed no more than 0.5 m/s at distance 10 cm 10 g Pu
False alarm frequency Set in the range 0.1 to 1.0 per minute
Power supply 4 batteries
Time of continuous operation 30 hours
Operating temperature range -40 to +50
Weight (without the rod and external moderator) 0.65 kg
Weight of the external moderator 0.4 kg
Dimensions of the control unit 1753737 mm
Dimensions of the detection unit Ø 65175 mm
Dimensions of the external moderator Ø 85175 mm

Additional information:

  1. 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.
  2. 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 neutron count rate.
  3. The monitor can scan transport vehicles and packages with the external moderator and scan people without it.
  4. The monitor has the automatic battery discharge indication.
  5. The monitor can be connected to PC via a standard interface.
  6. The detection unit can turn on 90.
