• Guaranteed resolution
• Low mass housing
• Less than 0.5 ppm of potassium
• Mu metal magnetic light shield

The Model 802 Scintillation Detector is a hermetically sealed assembly that includes a high-resolution NaI(Tl) crystal, a photomultiplier tube, an internal magnetic/light shield, an aluminum housing, and a 14-pin connector. It offers high efficiency and uniform response in both cylindrical and well configurations, with a proven record of long-term reliability and stability. The detector can be connected to the Model 2007 Tube base or the Model 2007P combination tube base and preamplifier.

Resolution is specified at the 662 keV peak of 137Cs, except for 802-2x.5, which is specified at 122 keV.
