MKS-11GN “SPECTRA” Search Dosimeter-Radiometer
A highly-sensitive and compact device intended to detect, localize and identify radioactive and nuclear materials by their gamma and neutron radiation as well as the amplitude gamma spectra. SPECTRA identifies radionuclides with indication of the category that they belong to (in compliance with the IAEA requirements).
It is used to prevent illicit transfer of these materials across the state borders, as well as at the companies and institutions dealing with gamma and neutron radiation sources.
A brand new search algorithm provides high sensitivity of the device and its instant actuation at the slightest change of gamma or neutron background level. New generation scintillation detectors with the silicon photomultiplier ensure high thermal stability of the device and entirely eliminate the “microphone effect”.
The device offers an outstanding user experience due to its innovative design, compact size, large colour display and a 200 hours continuous operation time.
Area of Use
