Description

SPECTRA radiometer is a high-sensitivity search device intended to detect, localize and identify radioactive and nuclear materials by their gamma and neutron radiation. 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.

SPECTRA product identifies radionuclides with indication of the category that they belong to (in compliance with IAEA requirements). There is an option to save and transfer 128 full gamma radiation spectra.

More

Radiation isotope identification device is controlled by the wrist device via Bluetooth technology. Thus measurements can be done remotely keeping out of danger. Measurement results can also be transferred to a personal computer through the Bluetooth channel.

Since 2002 according to the international technical assistance programs SPECTRA products have been supplied to the Border Guard Service of Ukraine, Internal Troops of the Ministry of Internal Affairs of Ukraine, the Ministry of Emergencies of Ukraine, the Border Services of Kazakhstan and Uzbekistan.

 

 

Purpose of Use

Purpose of Use

  • Measurement of gamma and X-ray radiation ambient dose equivalent rate (photon-ionizing radiation DER).

  • Determination of neutron radiation intensity.

  • Identification of radionuclide type.

  • Accumulation, storage of amplitude gamma spectra in the nonvolatile memory and their identification.

Features

  • High sensitivity gamma scintillation (CsI) detector, Geiger-Muller counter, scintillation (LiI) detector of neutron radiation.

  • Indication and automatic testing mode of power supply status.

  • Data communication between the detecting device (DD), the control and indication device (CID) and the PC is done via Bluetooth wireless technology.

  • Storage and transfer of 128 complete gamma radiation spectra.

  • Identification of radionuclides and their category(ies) (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-decay series, 238U-decay series.

    Note. List of nuclides that the device can identify may be extended if needed.

  • Threshold alarm system with three independent threshold levels:

    – search threshold level (threshold level of photon-ionizing count rate from the detector);

    – safety threshold level (threshold level of photon-ionizing radiation DER);

    – threshold level of neutron count rate from the detector.
