2"x2" NaI(Tl) Scintillation Detector

The Model NAI2/2P2 Scintillation Detector is a hermetically sealed assembly which includes a high resolution Dia. 2″x2″ NaI(Tl) scintillator, a 2″ photomultiplier tube, 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(<7.5%@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.
