- High sensitive scintillator CsI (Tl) with silicon photomultiplier
- Availability of amplitude spectrum (1024 channels)
- No microphonic effect
- Meets the requirements of IEC 61000-4-2:2008, IEC 61000-4-3:2007, IEC 61000-4-4:2008 standards
- Ingress protection rating IP67

Designed to measure dose equivalent rate of gamma radiation. Used for mobile laboratories, as a part of data panels and automated radiation monitoring systems.
It is produced using a high sensitive scintillator CsI (Tl) with silicon photomultiplier and a Geiger-Muller counter. If the customer chooses so, BDBG-09S can be made of duralumin or stainless steel. A special version of BDBG-09SV detecting unit with a waterproof housing IP68 has been developed for use in waters basins or artificial reservoirs.
BDBG-09S detecting unit can be used as a part of systems instead of BDBG-09 detecting unit for measurement of dose equivalent rate of gamma radiation and temperature without software change.
- Measurement of ambient dose equivalent rate (DER) of gamma radiation
- High sensitive scintillator CsI (Tl) with silicon photomultiplier and Geiger-Muller counter have been used.
- Data exchange between the detecting unit and the data display system through RS-485 interface.
- Availability of amplitude spectrum (1024 channels).
- Constant self-testing.
- Availability of the statistical accuracy of measurement.
- Ingress protection rating IP67.
- Average service life of the detecting unit – not less than 10 years.
