ARGOS is a software system to support the emergency organization to make the best possible decisions in case of incidents involving atmospheric dispersion of hazardous CBRN-materials.


ARGOS is useful throughout the entire disaster life cycle:

  • During the Preparedness phase for planning, dimensioning and training  - including evaluation of various 'What-if' scenarios
  • During the Response phase by calculating prognoses about how the situation will evolve; what can be the consequences of the dispersion; what the proper emergency or evacuation zones are; etc.
  • During the Recovery phase; what will be the effect of applying possible countermeasures; etc.
  • In the Evaluation phase to study what could have been done better and how could the situation have evolved?


ARGOS is a robust and mature product developed from more than 15 years of experience and intensive user involvement.

Today, ARGOS supports emergency management organizations in 13 countries covering more than 400 million people worldwide.


The ARGOS User Group is a group of public emergency management organizations using ARGOS, and participating in the further development of the ARGOS system.
