Description

High-sensitivity device intended to detect and localize radioactive and nuclear materials by their external gamma and neutron radiation. It is widely used by the Border Guard Service and environmental inspections to prevent illicit transfer of radioactive materials across the state borders.

Purpose of Use

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, X-ray and neutron radiation.

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

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

Features

  • New generation high sensitivity CsI scintillation detectors of gamma and LiI of neutron radiation with solid state (silicon) photomultiplier.

  • Color display with high resolution.

  • Integrated GPS/GLONASS-receiver.

  • No “microphone effect”.

  • High thermal stability.

  • Audio and vibration alarm of threshold levels exceeding.

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

  • The dosimeter communicates with a PC via USB-port.

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

  • Ingress protection rating IP67.
