The main components are:
The detectors are distributed in two arrays of 4 units for each side. 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 support structure is made of stainless steel, which can well resist to the weight of the equipment and to accidental bumps.
The weighting platform has a maximum limit of 6000 kg. Containers of different type and dimensions can be placed on the platform, up to a maximum of 100x100x200 cm (WxHxD). The operator interacts with FREE-AND 16 through a sophisticated yet easy-to-use software. To perform the measurement, the operator selects the proper geometry from a previously defined database, then sets the measurement time; the procedure automatically starts when the container is placed upon the weighting platform. Measurement reports are provided at the end of each scan. |
FREE-AND 16
SPECTROMETRIC STATION WITH SCINTILLATORS FOR CHARACTERIZATION OF RADIOACTIVE WASTE
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.
