    765BDBG-09 for Gamma Radiation Detection





    BDBG-09 is used both within data panels and automated systems of radiation monitoring to measure ambient dose equivalent rate of gamma radiation.

    A standard version of the detecting unit is produced with a built-in Geiger-Muller counter. A modification based on the scintillation detector is also available. Upon customer request the BDBG-09 housing can be made of duralumin or stainless steel. A special version of the detecting unit with waterproof housing has been developed for use in waterbodies and artificial reservoirs.

    BDBG-09 detecting unit has been successfully used for many years at nuclear power plants in Ukraine, France, Bulgaria and Korea.

    Purpose of Use

    • Measurement of ambient dose equivalent rate (DER) of gamma radiation.


    • Data exchange between the detecting unit and the data display system through RS-485 interface.

    • Constant self-testing.

    • Indication of the statistical measurement error.

    • Ingress protection rating – ІР67.

    • Average service life of the detecting unit – not less than 10 years.
