BDBG-09

Intelligent Detecting Unit of Gamma Radiation

• Сonforms to the CE standards
• Meets the requirements of IEC 61000-4-2:2008, IEC 61000-4-3:2007, IEC 61000-4-4:2008 standards.

Description

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.
BDBG-09 detecting unit has been successfully used for many years at many nuclear power plants.

Purpose of Use

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