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.

Typy detektorów

  • Scintillation CsI (Tl) detector with a photomultiplier for measurements in the range within 0.01 μSv/h to 50 μSv/h (spectrum-dose function)

  • Energy-compensated Geiger-Muller counter for measurements in the range within 50 μSv/h to 1.0 Sv/h
