    Description

    High sensitivity device intended to detect and localize radioactive and nuclear materials by their external gamma and neutron radiation. It is widely used to prevent the illicit transfer of radioactive materials.

    Upon customer’s request, we can produce CADMIUM in only gamma version (without a neutron channel).

    Purpose of Use

    • Search (detect and localize) for radioactive and nuclear materials by their external gamma and neutron radiation

    • Measurement of ambient dose equivalent rate (DER) of gamma and X-ray radiation (photon-ionizing radiation)

    • Indication of ambient dose equivalent rate (DER) of neutron radiation

    • Measurement of ambient dose equivalent (DE) of gamma and X-ray radiation

    • Determination of gamma, X-ray and neutron radiation intensity

    Features

    • High sensitivity CsI(Tl) scintillation detectors of gamma and LiI(Eu) of neutron radiation with solid-state (silicon) photomultiplier

    • Color display with high resolution

    • No “microphone effect”

    • High thermal stability

    • Audio and vibration alarm of threshold levels exceeding

    • Threshold alarm system with four independent threshold levels:

      – search threshold level (threshold level of count rate from the detector photon and neutron ionizing radiation)

      – safety threshold level (threshold level of photon ionizing radiation DER)

      – accumulated dose threshold level

    • Light color alarm (indication) of threshold levels exceeding (gamma radiation – red color, neutron – blue) and visual alarm on the side of the device

    • Dosimeter communicates with a PC via USB port

    • Powered by built-in lithium polymer storage battery that can be charged via USB cable

    • Software is used for:

      – reading measurement results and critical events from the dosimeter memory into the PC

      – report preparation and printout

      – display of the obtained dosimetric information with the GPS coordinates on the area map
