NRBC Simulation System

All over the world Armed Forces, Civil Defence, Emergency Services and First Responders have to face today the threat of Chimical, Biological, Radiological and Nuclear, CBRN, Attacks & Incidents.

The GSN NRBC (Nuclear, Radiological, Biological, Chemical) simulation software will provide realistic scenarios, destructions and casualties simulations to train your personnel to handle NRBC crisis.

In case of real life NRBC incidents, the NRBC simulation software will predict the affected zones to organize Emergency Services.

The software manages very complex simulations:

Nuclear risk
  • Multiplicity of radionuclide / Source term
  • Direct Cloud Shine
  • Wet (with the rain) and dry deposition

Biological risk
  • Risk decreases as solar radiation increases
  • Very low concentration

Chemical risk

  • Liquid droplets wide spectrum and primary evaporation
  • Secondary evaporation from ground
