The FREE-AND 16 spectrometric station is a robust and handy system designed to perform spectrometric analysis of waste materials, where the fine spectroscopy provided by HPGe-based systems is not needed.

The FREE-AND 16 main components are:

  • 16 NaI(Tl) 3”x3” scintillator detectors coupled to MCAs
  • Lead shielding for each detector, which also defines the scintillator field of view (collimation)
  • Mechanical support structure for detectors and weighting platform
  • Control PC with user-friendly software interface

The detectors are distributed in two arrays of 4 units mounted on each side of the stainless steel support structure.

Each detector is provided with a lead shielding, which acts as a collimator: this way each scintillator “sees” a defined portion of the container volume.

The system can achieve an MDA of 0.04 Bq/g (15 minutes measurement, 300 kg of material, 1 g/cm3 density).

The mechanical structure is designed to well resist to the weight of the equipment and to accidental bumps.

The maximum payload of the weighting platform is 6000 kg.

Containers of different type and dimensions can be placed on the platform, up to 100 x 100 x 200 cm (WxHxD).
