    Description

    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 modifications: BDBG-15S-09, BDBG-15S-23, and BDBG-15S-90, which differ in size and sensitivity of scintillation detector.

    Purpose of Use

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

    Features

    • Scintillation CsI (Tl) detector with a photomultiplier for measurements in the 0.01 μSv/h to 50 μSv/h range (spectrum-dose function):

      – 9 cmfor BDBG-15S-09

      – 23 cm3 for BDBG-15S-23

      – 90 cm3 for BDBG-15S-90

    • Energy-compensated Geiger-Muller counter for measurements in the 50 μSv/h to 1 Sv/h range

    • High sensitivity regardless of minimum weight and dimensions

    • Ability to extend a measurement range up to 5 Sv/h (at request)

    • Availability of amplitude spectrum (1 024 channels)

    • High mechanical immunity

    • No microphone effect
