[en] An Environmental Radiation Monitoring System has been developed and is being tested in the NRCN to be an auxiliary tool in case of a nuclear accident, The system collects real-time environmental data such as: gamma radiation, wind speed and direction, and temperature. The system also stores malfunctions arid status of the data loggers. This is done by the main server, or the secondary server which is the backup. The collected data from the stations is stored in a local database for future processing Users have a Graphical User Interface (GUI) as front-end display that presents the collected data on a geographic map (GEO) Radiation values are colored according to predefined threshold levels The GUI enables users to view various types of graphs and reports over different cross sections. In addition, parameters like radiation thresholds and sampling time, that impact the station operation modes are defined via GUI and uploaded to the stations
