BDBG-09 is used as a part of automated systems of radiation monitoring to measure ambient dose equivalent rate of gamma radiation in waterbodies and artificial reservoirs. The detecting unit is produced in hermetic stainless steel housing with IP68 ingress protection rating. Maximum depth of immersion – 20 m. When immersed in water the detecting unit withstands water temperature from +3 °С to +60 °С.
A standard version of BDBG-09 is produced with a built-in Geiger-Muller counter. A modification based on the scintillation detector is also available.
