RADLab

The Radiological Assay and Detection Lab (RADLab) is a radiation laboratory that specialises in advanced radiometric diagnostics using gamma-ray and neutron detectors.

Overview

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

Based within a leading fusion research facility, we are dedicated to delivering high-precision radiometric measurement services and pioneering diagnostic solutions that support the development, optimization, and safety of fusion energy systems.

Our mission is to empower the global fusion community with reliable, data-driven insights that accelerate the path to sustainable, clean energy.

Capabilities

Our operations are built upon five core pillars that define our approach and drive our impact:

  • waste assay services
  • research support services (measurements supporting both internal and external fusion-based research programmes)
  • experimental benchmarking of neutronics codes
  • neutron diagnostics research and development
  • gamma diagnostics research and development

The RADLab’s radiometric systems include static and portable High Purity Germanium (HPGe) detectors, diamond detectors, and Thermoluminescent Dosimeter (TLD) reading capabilities. These systems assist the RADLab team in providing measurement services and training opportunities for universities, training providers, and industry.

ADRIANA

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.

Access RADLab

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

Contact RADLab team

The sample acceptance criteria for the RADLab are as follows:

  • Dose Rate: 0 µSv/hr to 123 µSv/hr contact
  • Contamination: Low or in sealed container
