Cell Characterisation system: CC-RIAS

ImiTec’s patented Remote Isotopic Analysis System (RIAS) forms the core technology of our new Cell Characterisation system: CC-RIAS. This system was developed specifically for assisting nuclear decommissioning, with support from InnovateUK. The CC-RIAS provides the ability to map, measure and characterise radioactivity in confined or difficult to enter places, thereby improving the quality of data needed for planning and undertaking plant decommissioning. By more accurately understanding the location of any radiation hazard the risk to personnel can be reduced.

CC-RIAS is configured to provide 3D radiation scans in plant-type settings, being small and light enough at 1.2 kg to mount on a robotic manipulator. It uses a micro gamma-spectrometer, capable of recording up to 30,000 counts per second at energies between 30 keV and 3.0 MeV. The Kromek Ltd. GR-series spectrometer can be hot swapped between a 10x10x10mm CZT crystal and a 5x5x5mm crystal for mapping in very high dose environments.

CC-RIAS offers a manual or robot deployable approach that involves coincident LiDAR scanning with collimated gamma spectrometry mapping to provide coincident measurements of gamma ray-path distances to surrounding surfaces and the associated incoming radiation intensity from each target point in the scan. Conceptually, this allows a more accurate 3D dose map to be obtained by the scanning system and from only a small number of scanning positions.

Key Features

  • Remote Operation – Units can work in confined spaces deployed manually e.g. on a tripod, mechanically on a manipulator or using a robotic platform. CC-RIAS is controlled via a cable connection to a remote base station placed up to 50m away. Power can be supplied via the control cable or via an on-board battery unit. Device weighs 1.2 kg, with a diameter of <20cm, suitable for cell access via 8” pipes.
  • 3D spectral analysis -Units record coincident 3D data using a LiDAR coupled next to a lead (Pb) collimated Kromek Ltd. GR-series micro-gamma spectrometer. Spatial resolution and counting time can be modified to suit the facility and gamma dose.
  • We can be contracted for surveys – Including working with specialty partners such as the NNL and Kuka Robotics Ltd.
  • We also provide training – with leading radiation detection experts to help you get the most from your kit.
