RADLab

The Radiological Assay and Detection Lab (RADLab) is a low contamination, medium dose facility – 0 µSv/hr – 123 µSv/hr contact – with multiple radiometric system for measuring gamma-rays, neutrons, and providing measurement services and training opportunities for universities, training providers, and industry.

The RADLab’s radiometric systems include static and portable High Purity Germanium (HPGe) detectors, Diamond detectors, and Thermoluminescent Dosimeter (TLD) reading capabilities.

The RADLab houses the UKAEA part of the Advanced Digital Radiometric Instrumentation for Applied Nuclear Activities (ADRIANA). ADRIANA, combining facilities at UKAEA, Lancaster University and the University of Liverpool, is a suite of digital radiometric instrumentation that forms part of the National Nuclear User Facility (NNUF). In addition, the RADLab maintains instrumentation for high resolution gamma spectroscopy with Compton suppression and cosmic veto, real-time fast and thermal neutron spectrometry, and low dose monitoring, as well as a growing capability to custom-build electronics.

Users can access the RADLab facilities in a number of ways:

  • Hands-on training and experience with all or a selection of the equipment
  • Access to the equipment for taking measurements
  • Loan of the equipment
  • Dedicated UKAEA resource to take measurements on your behalf

If you are interested in accessing the lab and would like to discuss further, please get in touch: Enquiries@RADlab.ukaea.uk
