NUCLEAR & NON-NUCLEAR WASTE CHARACTERISATION

GAU-Radioanalytical has a proven track record in the characterisation of a diverse range of radionuclides in varied sample types. The laboratory routinely handles sample activities ranging from materials being screened against free release criteria to LLW and certain forms of ILW. GAU specialises in developing radionuclide fingerprints for wastes relative to key indicator radionuclides and in the characterisation of wastes for radionuclide, trace metal and complexant concentrations. It also routinely performs analyses in support of land remediation and post decommissioning assurance monitoring. In all cases, GAU will provide comprehensive advice on sampling, sample storage and analytical strategies ensuring the delivery of a cost effective and robust analytical programme.

  • Extensive track record in the characterisation of a diverse range of radionuclides in a wide range of complex matrices.
  • Well equipped, modern laboratories and highly trained, experienced staff providing a cost effective and efficient radioanalytical service to agreed timescales.
  • Advice, support and feedback provided throughout the lifetime of the project.
