    Description

    BDBG-09W 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.

    A standard version of BDBG-09W is produced with a built-in Geiger-Muller counter.

    A modification BDBG-09SW based on the scintillation detector is also available.

    Purpose of Use

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

    Features

    • Gamma detecting unit based on the Geiger-Muller counter

    • Hermetically sealed stainless-steel housing

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

    • Constant self-testing

    • Indication of the statistical measurement error

    • When immersed in water, the detecting unit is resistant to exposure of:

      – water temperature from + 3 to + 50 °С

      – maximum depth of immersion in water 20 m

    • The detecting unit is resistant to sinusoidal vibrations according to regulatory documents
