General Description
The identiFINDER is the world’s first in a series of handheld instruments capable of detecting the presence of gamma radiation and identifying the radionuclide. Every identiFINDER is able to detect, rapidly locate, accurately measure and precisely identify sources or contaminations from 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 allows a wide application scope. The identiFINDER 2 is a logical extension of the original identiFINDER series of handheld radio- isotope identification detector (RIID) instruments.
Technical Description
The identiFINDER includes a NaI or LaBr detector plus a GM tube, for high gamma dose rate measurements is also one of the first handheld instruments to implement Digital Signal Processing (DSP).Three push buttons that align with on-screen menu items are all that is needed to operate this instrument, even with only one gloved hand. The monochrome LCD display has been replaced with a TFT LCD, 64k color, 320 by 240 pixel display that is readable in virtually all light conditions. The spectrum of the ultra-versions is continuously LED peak stabilized to handle a wide range of count rates and conditions with no peak interference in the identification spectrum.
