Whether you are evaluating water or soil sample or searching for materials that could make a dirty bomb, it’s critical to know the exact isotope of the radioactive material in order to assess the potential threat and quickly initiate a plan of action. The Thermo Scientific™ RIIDEye™ X and RIIDEye M Handheld Radioisotope Identifiers, with patented Quadratic Compression Conversion (QCC) technology, are well suited to support users from homeland security operations to contamination monitoring and remediation, with the industry’s fastest, most accurate and easy to use RIID.

The RIIDEye X Handheld Radiation Isotope Identifier is the next generation of rugged devices designed to withstand the demanding environment in which first responders, security forces and military operate. It offers a comprehensive list of features:

  • Unique live spectrum building gives users ability to optimize identification scans in real-time.
  • Easy to use SNM Assist maximizes SNM detection by auto-calculating scan times to achieve high confidence results.
  • Color coded peaks in spectrum quickly identify isotopes and classify them for rapid response.
  • Excellent ID speed and accuracy of detection in 30 sec or less.
  • Improved Auto Cal allows stabilization in High BG.
  • Large gamma detector for excellent sensitivity.
  • Low cost of ownership from acquisition to maintenance with free coarse-calibrations and bi-annual optimization of system and free firmware upgrades for life of ownership.
  • Documented ANSI N42.34-2006 compliance.
  • CLYC Neutron detector uses no He3 and is located in handle utilizes body moderation to maximize detection performance.
  • Mechanical Design:  Rugged, IP65 and drop resistant to 1m.
  • Excellent weight balance for long use with included shoulder strap and ergonomic handle.
  • More than 45 different isotopes included in Library with user ability to add new libraries and isotopes.
  • Easy data offload via USB memory card or live via serial port connection.
  • Data is compliant with ANSI N42.42-2006 and can be used by most analysis SW including Cambio and PeakEasy.
  • Headphone jack for completely silent operations or operations in high background noise
  • High capacity rechargeable battery lasts 8 hrs or more and can be powered via 6 AA batteries.
  • Includes Pelican™ case with Alkaline battery adapter, shoulder strap, power supply, USB memory card reader.
  • Options: GPS, spare memory card, communication cable, radioactive test adapter.
  • Detector Options: 2"x2" NaI or 1.5"x1.5" LaBr.

The RIIDEye M Handheld Radiation Isotope Identifier comes in a multi-configuration, multi-purpose package. It contains the same detection SW and user interface as well as many of the features of the RIIDEye X but its mechanical design is ideally suited for field laboratories and environmental studies. The following features differ from the RIIDEye X:

  • Moderated CLYC Neutron detector uses no He3 and is located in electronics case to maximize space.
  • Removable gamma detector allows close inspection of samples with included 5ft extension cable and can be combined with a low background shield for low radioactivity levels in samples such as food, soil or water.
  • Mechanical Design: IP40, multi-configurable, ideally suited for field labs and laboratory use
  • Includes Pelican case with Alkaline battery adapter, shoulder strap, power supply, USB memory card reader, 5ft detector extension cable. 
  • Options: spare memory card, communication cable, radioactive test adapter.
  • Detector Options: 2"x2" or 3"x3" NaI, 1.5"x1.5" LaBr.
