PNAI series

ENVIRONMENTAL 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 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.

In addition to standard supply, the following options are available upon request:

  • Aluminum airtight holders with mounting flange for duct mounting: models PNAI/ATH and PNAI/3/ATH
  • In order to reach the maximum of sensibility required in air monitoring (1 Bq/g), the high sensibility air monitoring system option with SDU-1M is available for the 2” x 2” PNAI detector, with 10 cm lead shielding , Marinelli 3 l beaker, and 16 m3/h air pump
  • PNAI 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.
