EU-RADION concept

The overall concept for the EU-RADION is to design and develop a complete and operational system for the detection and identification of RN materials designed mainly for first responders. The whole system applies novel software as well as hardware solutions tailored to the preparedness and response actions of practitioners in the RN domain. In order to detect the RN hazard, the system uses the network of sensor integration units, which are adapted to both stationary and mobile (swarm of UGVs and person-worn) assets. Each sensor integration unit comprises 3 sensors including a Geiger counter, a Cadmium Zinc Telluride detector and a gas sensor. This composition of the unit allows to estimate the radiation dose rate and identify the RN agent/isotope. Identification is possible through the analysis of spectra generated by the CZT sensors. The spectrum (CZT output) is specific for a certain nuclide. The spectrum will be matched with the RN nuclide system library. The application of a gas sensor, as a supporting component, will serve the purpose to detect the presence of hydrogen, whose level significantly increases during an explosion. The power source will be adjusted in order to allow an operational period required by stakeholders and practitioners. Communication between the system and deployed SIU will be wireless allowing for mobility of the network.

The system will be able to monitor the RN hazard in real-time. One of the core components of the system will be the dispersion engine, which will calculate the dispersion model for the RN material. The dispersion engine will fuse the data from all deployed sensor integration units including the stationary ones, the swarm of UGVs, and person-worn units in the area in order to generate a threat map as well as estimate the potential source/direction of the hazard. The measurements will be updated in real-time. The output of the dispersion engine, i.e. threat map and estimated source, will be visualised in the Tactical Command tool, which will create a joint operational picture for the command centre. The system will also support real-time positioning and monitoring of system units and personnel. For this purpose, an inertial navigation system module supported with a global navigation satellite system will be implemented.
