BDBG-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.

Branches of Use

Radiological Labs, Radioactive Waste, Medical and Ecology.

Purpose of Use

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