identiFINDER R500 (formerly radHUNTER)
Next Generation Handheld Radionuclide Identification Device
The identiFINDER R500 (formerly the radHUNTER™) is an extremely sensitive and accurate digital hand-held gamma radionuclide identification device (RIID).
Available in two configurations (NaI and LaBr), the R500 is able to quickly detect, rapidly locate, accurately measure and precisely identify sources of contamination from their gamma radiation signature.
The R500 NGH uses a 0.75" thick by 4" diameter NaI(Tl) detector while the R500 LGH ultra 3n uses a 1.5" by 1.5" LaBr3:(Ce) detector. Both instruments come with a GM tube for high gamma dose rate measurements and a sealed He3 detector with moderator for neutron detection. Each instrument is supplied in a carrying case with battery charger, communication cables, synchronization and analysis software.
Variations in normal operating conditions can affect the performance of RID with scintillation detectors such as NaI(Tl) and LaBr3:(Ce). Dramatic temperature variations can affect the scintillation detector and/or the PMT and can also cause instabilities and non-linearities in the electronics. In addition, high count rates can impact the peak position in a spectrum. The R500 instruments have been developed to correct all these circumstances through automatic calibration and continuous LED stabilization.
