The radHUNTER™ is an extremely sensitive and accurate digital hand-held gamma radionuclide identification device (RID). It is the culmination of over eight years of development of micro-miniature, digital signal processing electronics; operating power conservation; and advancements in the scintillation detector, radionuclide template matching identification algorithm. The radHUNTER development was supported in part by the U.S. Department of Homeland Security (DHS) / Domestic Nuclear Detection Office (DNDO), Human Portable Radiation Detection System (HPRDS) program.
Available in two configurations (NaI and LaBr), the radHUNTER is able to quickly detect, rapidly locate, accurately measure and precisely identify sources of contamination from their gamma radiation signature.
The radHUNTER NGH ultra 3n uses a 0.75″ thick by 4″ diameter NaI(Tl) detector while the radHUNTER 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 recharging unit, 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 radHUNTER instruments have been developed to correct all these circumstances through automatic calibration and continuous LED stabilization.
