Ecotest - Model MKS-11GN SPECTRA -Search Dosimeter Radiometer

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.

Available in two colours: yellow and olive green (NATO green). Upon customer’s request, we can produce SPECTRA in only the gamma version (without neutron channel).
