Description

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. BDBG-09S detecting unit can be used as a part of systems for measurement of dose equivalent rate of gamma radiation and temperature.

Purpose of Use
Measurement of ambient dose equivalent rate (DER) of gamma radiation

Features

• High sensitive scintillator CsI (Tl) with silicon photomultiplier and Geiger-Muller counter have been used.

• 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.
