The system is based on a classical hierarchy structure complemented with necessary links.

Level I: Primary Information Sources:

• Dose-rate meters to be installed at a distance between several hundreds of meters and several kilometers.
• Automatic Radiation/Ecology Stations (ARES) are nodal stations in the monitoring network and are designed to monitor the presence of radiation and chemical contaminants in air and measure isotopic contamination composition.
  
• Weather hardware to measure wind velocity distribution in the near-earth layer and at altitudes up to 300 m.
  
• Satellite data transmission stations.
  

RSC Energia communication satellite; Dosimetric sensors, spectrometers with data relay radiolink; Satellite communication antenna; Automatic radiation and ecological station.

Level II: Information acquisition, storage, processing, analysis and presentation subsystem, which is aimed at:

• Control and monitoring of the automatic continuous measurement system.
  
• Real-time processing and presentation of the incoming information, covering visualization of the radiation data by using geoinformation systems.
  
• Warning against the monitoring and emergency levels breakdown, as well as early detection of the objects accidents causing radioactive substances egress into environment.
  
• Presentation of the radiation monitoring data.

Level III: Accident Progress Simulation and Prediction and Management Decision-Making Support Subsystem, which provides solution of the following basic tasks:

• Analysis, prediction and visualization of the radiation situation data based on the basic models of radioactive contamination propagation into environment, and geoinformation systems.
  
• Generation of recommendations, and scientific and technical support of the management-made decisions.
  
• Report preparation and submission to top-level systems and appropriate authorities.
