SPECTRA

SPRD SPECTRA is intended to detect, localize and identify radioactive and nuclear materials by their gamma and neutron radiation as well as the amplitude gamma spectra. The device identifies radionuclides with indication of the category that they belong to (in compliance with the IAEA requirements). It is used to prevent the illicit transfer of these materials across state borders, as well as at the companies and institutions dealing with gamma and neutron radiation sources.

Purpose of Use

  • Identification of the radionuclides type by their amplitude gamma spectra
  • Determination of gamma and neutron radiation intensity
  • 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
  • Saving amplitude gamma spectra and events logs in the non-volatile memory

    Note: The list of nuclides the device is able to identify may be extended if needed
  • 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
  • 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
    Display of the accumulated spectra
Branches of Use:
  • Radioactive Waste Storage Sites
  • Sanitary dosimetry and ecology
