ARGOS Introduction


An accident in a Nuclear Power Plant (NPP) was the original target for ARGOS prognoses. The famous Chernobyl accident in April 1986 initiated the development, in Denmark and the ARGOS system was developed.


ARGOS includes gaseous, liquid, or multi-phase outflow from pressurized containers; evaporation from a boiling or volatile pool; and heavy-gas dispersion form continuous and instantaneous sources. For calculating of chemical releases, ARGOS comes with an advanced integrated source model developed by RISOE.

ARGOS supports the decision making concerning preparedness (strategy, organization, system and equipment infrastructure) enabling a true understanding of operational decisions during the entire CBRN life cycle.

ARGOS facilitates the dialogue to enable multinational and interregional collaboration and the cooperation between multiple agencies in defining guidelines for joint / coordinated operational plans and SOPs identifying the needs for equipment, e.g. personal protective equipment, CBRN detectors training to the CBRN threats, operational plans and SOPs.

General Functionality


ARGOS is an Information System (IS) for enhancing Crisis Management for incidents with CBRN releases. The target is accidents as well as terrorist initiated events related to CBRN industries, transports of hazardous materials etc.


ARGOS is a prognostic tool as well as a database system for collection and presentation of data relevant for emergencies in an easily understandable form.


ARGOS facilitates decision support, improving of situation awareness and information sharing among the Emergency response organizations. As a simulation instrument, ARGOS is also valuable for training of the response organization.


The mission of ARGOS is to support the emergency organization to make the best possible decisions in case of a CBRN incident.  The objectives of ARGOS are:

  • Situation awareness
  • Prognosis of how the situation will evolve
  • Calculate consequences of an incident
  • Decision support for countermeasures
  • Information to the public
  • Follow-up and evaluation
  • Dimensioning of emergency preparedness
  • Training and exercises
