5"x5" NaI(Tl) Scintillation Detector

The Model NAI5/5P5 Scintillation Detector is a hermetically sealed assembly which includes a high resolution Dia. 5″x5″ NaI(Tl) scintillator, a 5″ ET Enterprises photomultiplier tube(9390KB), an internal magnetic/light shield, an aluminum housing and a 14-pin connector.

This kind of 14-pin NaI(Tl) detectors have good energy resolution(<8.5%@662keV) and stability, their standard 14-pin connector can be easily inserted in plug-on photomultiplier tube(PMT) base or digital Multi-Channel Analyzer(MCA) for Gamma-ray detection systems.
