Got a Question?

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).

To obtain information about our products during the preparation of tender or contractual documentation, please contact our representatives via the provided contacts. We continuously improve our products and expand their functionality in line with market needs by applying the latest technologies, modern components, and materials. Therefore, specifications, descriptions, and configurations are subject to change without prior notice.

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 or sigma-threshold (a threshold level of pulse count rate from the detector of photon-ionizing radiation)
    • safety threshold level (a threshold level of DER photon-ionizing radiation)
    • neutrons threshold level (a threshold level of count rate from the neutron detector)
    • accumulated dose threshold level (a threshold level of photon-ionizing DE)
  • 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

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

Delivery Kit

  • search alarm dosimeter
  • charger
  • shielded USB cable
  • “Spectra Reader” software (on a mini-CD or other electronic media)
  • operating manual
  • packing case
