PNAI Series

DETECTION UNIT FOR GAMMA RADIATION WITH NaI(Tl) SCINTILLATOR

The PNAI detection unit is based on a NaI(Tl) scintillator probe, designed for high sensitivity gamma radiation measurements; these probes best apply to the detection of small activity concentrations in air and in gas exhausted from controlled zones.

The series comes with two detectors versions: PNAI with 2” x 2” crystal dimensions; PNAI/3 with 3” x 3” crystal dimensions.

The NaI(Tl) scintillator includes a 2” 14 pins photomultiplier, connected to the ELSE NUCLEAR photomultiplier base model PAD; the PAD provides power supply, preamplification, output signal discrimination and digital conversion, allowing to connect a reading unit and manage the acquired data.

 
PNAI series detectors can be used in stand-alone connected to ELSE NUCLEAR's ratemeter or as a part of a monitoring system.

Aluminum airtight holders with mounting flange for duct mounting are available as accessories (PNAI/ATH or PNAI/3/ATH).

The PNAI probes can also be connected to a multichannel electronics module, to be used in MISTRAL XM air/stack monitoring systems: this option is called PNAI-MC.
