Real-time radiation monitoring underwater
FLIR’s identiFINDER R425 UW delivers accurate and reliable radiation detection in underwater environments. This Radionuclide Identification Device has a rugged, durable design allowing it to operate in difficult conditions and is intended specifically for prolonged use underwater and in high humidity. It provides data in real-time, making it invaluable for environmental monitoring, emergency response, and industrial safety.
Reliable detection, even in high background radiation environments
With an IP68 rating, the R425 UW is fully protected against water ingress and can operate at depths of up to 20 metres (66 feet). It is built for extensive underwater radiation monitoring and emergency situations, such as in the wake of radiation leaks from industrial or maritime accidents.
Equipped with a high-capacity GM tube, it has an increased dose range capability to 10 Sv/h. This ensures reliable detection, even in higher activity environments. The R425 UW has two detector options available:
- NaI offering standard energy resolution.
- LaBr offering superior energy resolution.
Supporting EOD dive operations
From clearing submerged ordnance with suspected radioactive components to surveying contaminated wrecks or legacy dump sites, the R425 UW gives EOD dive teams the ability to detect, identify, and respond to radiological threats quickly and effectively. Its rugged design, underwater capabilities, and precise detection makes it a valuable tool for EOD dive operations.
