Scanning systems - contamination in waste/decommissioning materials

This category includes all the available object monitoring systems up to date. Depending on the type and dimensions of the object to be monitored and/or characterised, they can be divided in:

  • Systems for free release of decommissioning materials (FREE-AND 16)
  • Systems for waste containers and drums (AURAS 3000 and ADAMOS series)
  • Systems for pipes (PIPE SCANNER)
  • Systems for bags containing contaminated material (ARCHIMEDES II 9102 WiFi)
  • Systems for excavation material (ARCHIMEDES III 9103)
  • Systems for small objects (CARONTE 9400 and BOX COUNTER)
  • Systems for hospital waste (MHOS 9700 HWM series)

These systems are employed in hospitals, decommissioning sites and facilities, and in all applications where there is a need of waste clearance before free release for radioactivity risk.

The BOX COUNTER system is designed to perform a fast gamma radiation monitoring of laundry, waste bags, tools and other small objects.

The CARONTE 9400 gamma monitor is designed to easily measure the radioactivity level of small objects such as boxes, tools or other similar equipments.

The MHOS 9700 HWM series gamma monitors are specifically designed to measure the radioactive contamination level in hospital waste materials carried through the measurement area in small containers. As an option, the MHOS 9700 HWM-S can be equipped with a thin window panel in front of the detector, which allows to perform beta-gamma monitoring. 

- MHOS 9700 HWM-N and MHOS 9700 HWM-P: two columns, each housing a detector, define a passageway between them; the system allows to automatically detect sources - or contaminated material - passing through.

- MHOS 9700 HWM-S: a single column houses one detector and a scale; the system performs a static measurement which is automatically activated by positioning the material directly upon the scale.

The ARCHIMEDES II 9102 WiFi is designed to perform fast measurements of the gamma activity of bags, containing waste materials coming from the Nuclear Power Plants Decommissioning or from plants where high neutron flows were used.

The FREE-AND 16 spectrometric station is a robust and handy system designed to perform the weighting and spectrometric analysis of materials, coming from nuclear power plants decommissioning activities. The performed measurements are typically used to determine the mass activity concentration.

The system is designed to perform a complete and accurate scanning of both the internal and external surfaces of pipes, e.g coming from decommissioning of Nuclear Power Plants.

AURAS-3000 is a highly automated system for measuring a variety of sample sizes and forms (bags, boxes, barrels, and B25 containers), with densities approximately in the range 100 kg/m3 to 2000 kg/m3. The system uses four mechanically cooled HPGe spectrometers. 

Analysis of spectra is performed with the ORTEC ISOTOPIC waste assay software operating under the control of a user interface developed with National Instruments LabVIEW.

ADAMOS is an automated Segmented Gamma Scanner station, designed to measure drums containing solid radioactive waste materials.

ADAMOS stations can be adapted to specific requirements, through a customization of the mechanical configuration and/or the measurement equipment here described.

The portal monitor ARCHIMEDES III 9103 is designed to measure the radioactivity level in excavation materials of various nature, to define their proper destination as far as their release in the environment is concerned.
