SPECTRA - Search dosimeter-radiometer MKS-11

Be the first to review this product


MKS-11 “Spectra” search dosimeter-radiometer is designed to measure ambient dose equivalent rate of gamma and X-ray radiation (hereinafter called photon-ionizing radiation DER), to determine neutron radiation intensity, as well as to identify gamma radionuclides. The device provides accumulation, saving in the non-volatile memory and identification of amplitude gamma spectra.

Description

Details

The device is used to detect and localize radioactive and nuclear materials relative to their gamma and neutron radiation with the aim to prevent illicit transfer of these materials. It is also used at enterprises and organizations dealing with gamma and neutron radiation sources.

Features:

  • High sensitivity gamma scintillation (CsJ) detector, Geiger-Muller counter, scintillation (LiJ) detector of neutron radiation.
  • Mode of indication and automatic testing of batteries residual capacity.
  • Data communication between the detecting device (DD), the control and indication device (CID) and the PC is done via Bluetooth wireless technology.
  • Option to save and transfer to personal computer 128 full gamma radiation spectra.
  • Identification of radionuclides with indication of the category that they belong to (in compliance with IAEA requirements):
  • medical radionuclides: 18F, 67Ga, 99mTc, 111In, 123I, 131I, 201Tl;
  • industrial radionuclides: 57Co, 60Co, 133Ba, 137Cs, 192Ir, 152Eu and 241Am;
  • special nuclear materials: 233U, 235U, Pu [reactor-grade plutonium (more than 6%240Pu)];
  • naturally occurring radioactive materials: 40K, 226Ra, 232Th and daughters, 238U and daughters.


Note: The list of nuclides that can be detected by the device can be enlarged if needed.

  • Threshold alarm system with three independent threshold levels:
    • search threshold level (threshold level of pulse count rate from the detector of photon-ionizing radiation);
    • safety threshold level (threshold level of photon-ionizing radiation DER);
    • threshold level of pulse count rate from the detector of neutron radiation.
