As part of the BRIDGE-BS project, an underwater radionuclide sensor was successfully tested and calibrated in the lab and in a water tank. Unlike older systems, this sensor can provide precise measurements of radioactivity in still water, shown in units of Bq/m³.
After completing all the necessary preparations, BRIDGE-BS partners HCMR and IO-BAS deployed the system in the Black Sea to monitor radioactivity in a specific marine area in Varna. The setup, which includes both the sensor and a communication box, was installed on a fixed platform in the sea. It was also combined with other instruments, such as a CTD sensor, a DO sensor, and a chlorophyll-a sensor.
The goal is to develop a smart detection system with energy and communication autonomy, and integrated automated analysis to rapidly inform policymakers of potential or suspicious threats.
The system has now been running for a week, sending real-time data to the lab’s monitoring center. Early results are already being reviewed. This is an important first step toward setting up a permanent station that could provide continuous data in coastal areas where mobile networks are available.
This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 101000240.
