Detecting Unit of Gamma Radiation

BDBG-15S

BDBG-15S is designed to measure ambient dose equivalent rate of gamma radiation in a wide range of values.

Suitable for unmanned aerial vehicles, mobile robotic devices, and automated systems of radiation monitoring.

BDBG-15S is available in three versions BDBG-15S-09, BDBG-15S-23 and BDBG-15S-90, which differ in the size and sensitivity of the scintillation detector.
