On 18 May 2023, NUVIA a.s. organized RadTech at the Vyškov Airport, a workshop aimed at presenting a wide range of airborne, mobile and stationary radiation monitoring equipment with a focus on practical demonstrations of the ionizing radiation source localization. In cooperation with colleagues from the NUVIA Group, namely from Germany or France, as well as the Czech Army, the Czech Fire Rescue Service, the Czech Metrology Institute, the State Institute of Radiation Protection, the Defence University and LIAZ, we had a unique opportunity to present our products in action to customers and partners in the field of radiation monitoring.
The workshop began at the Dědice barracks with presentations by individual participants and introduced the attendees to the dynamic demonstration at the airport. The aim of the demonstration was to simulate a radiation event – the search for a lost/uncontrolled radiation source that was located on the airfield.
After the shared transfer of the participants from the barracks to the airfield, the dynamic demonstration started with an aerial survey by system AIRIS , which was installed in a Mi-17 military helicopter Further tracing of the source was to take place with the help of a LIAZ unmanned helicopter- SKYSPOTTER with the HPGe detector module of LIAZ a.s. and next, drones from the NUVIATech Instruments product line namely DRONES-G , the newly developed DRONES-G MINI and the DGI NuFLIGHTER drone with CZT detector. However, due to windy weather, these UAVs could not be used.
This was followed by a ground survey, which was initiated by the Army’s S-LOV CBRN vehicle. This was followed by two other mobile vehicles – the technical vehicle TACH D from the Fire Rescue Service of the Czech Republic (HZS ČR) and the mobile laboratory MORA VAN of the State Institute of Radiation Protection. The mobile survey was carried out by members of the Army of the Czech Republic and the Fire Rescue Service, who carried a PGIS-2 mobile spectrometer, GalaXray handheld spectrometer and gamma camera – NuVISION .
The Fire Department’s sampling team secured the radioactive radiation sources and transferred them into a shielded container. The dynamic demonstration ended with the decontamination of vehicles and people within the complete decontamination line of the Fire Brigade.. After leaving the defined area, the mobile team returned via the monitoring PORTAL D . The whole situation was secured by the stationary monitoring systems RAMS with continuous transmission of radiation data.
At the end of the dynamic demonstration on the airfield, the participants returned to the barracks where the measured data were presented, evaluated and compared between the different instruments.
