2014 R&D 100 Winner
Thermo Fisher Scientific's RIIDEye XPortable, handheld radioisotope identification instrument (RIID) technology typically uses one of two types of detector material—sodium iodide (NaI) or lanthanum bromide (LaBr)—in combination with a multi-channel analyzer to segregate pulses from specific gamma energies, that provides a gamma energy spectrum used to identify a specific radioisotope. Detectors, particularly in portable RIIDs, often require an increased time (60 sec) to acquire enough statistics to provide valid and accurate identifications. This prevents effective scan presetting. The RIIDEye X, a handheld radiation isotope identifier developed by Thermo Fisher Scientific, eases this bottleneck with Special Nuclear Material (SNM) Assist, which provides optimal scan time recommendations through the application of patented Quadratic Compression Conversion (QCC), which provides real-time spectra builds of source identifications during the scan. This Spectra Build feature gives users a visual description of the radiation, which gives insight into the data acquisition and shows the building statistics that users can easily review. Based on the stability of the spectrum, users can add additional scanning time. RIIDEye X’s neutron detector uses no He3 and is located in the handle to enhance performance detection.
