identiFINDER™

The identiFINDER™ instrument series is a family of hand-held, digital gamma spectrometers.  Every identiFINDER is able to rapidly locate, accurately measure and precisely identify sources or contaminations emitting gamma radiation.  The ability to detect X-ray sources as well as the presence of neutrons in the radiation field via an optional neutron detector enhances the identiFINDER’s capability.

This standard identiFINDER™ includes a 1.4” (35 mm) diameter x 2” (51 mm) long NaI (Tl) detector plus a GM tube, for high gamma dose rate measurements. With the exception of the identiFINDER™-X, every unit is supplied with a carrying holster plus a wrist strap, serial cable, battery pack for rechargeable and non-rechargeable batteries, charging unit, download and analysis software and a carrying case with shoulder strap.

Individual identiFINDER™ models are available with different types and sizes of detectors and with special software. An optional, sealed ³He neutron detector with internal and external neutron moderator can be added for neutron detection.

Variations in normal operating conditions can affect the performance of radio-isotope identification devices (RIID) with scintillation detectors such as NaI(Tl) and LaBr₃.  Dramatic temperature variations can affect the scintillation detector and cause instabilities and non-linearities in the electronics. High count rate changes will also impact the peak position in a spectrum. The identiFINDER family of instruments has been developed to correct all these circumstances through different solutions for automatic calibration and continuous stabilization.
