The article describes the main requirements for the geo-information system (GIS) of radioecological monitoring of atmospheric air, terrestrial and aquatic ecosystems in the vicinity of nuclear and radiation hazardous facilities. The analysis of GIS and decision support systems (DSS) using GIS-technologies during radioecological monitoring, the assessment of the consequences of radioactive contamination of territories and their remediation has been carried out. The analysis of software products for developing the GIS has been presented and a list of programs, the use of which would be the most effective at the development of GIS project for the support of radioecological monitoring, has been proposed. The scheme of radioecological monitoring using geo-information technologies, as well as the structure and composition of the GIS project have been presented in the paper.
