Wood operates one of the UK's largest independent radiochemistry laboratory facilities for all aspects of radiochemical and radionuclide analysis. The laboratory is accredited by the United Kingdom Accreditation Service (UKAS) for a diverse range of analyses and matrices.

We provide analysis for nuclear operators, decommissioning contractors, contaminated land consultants, local authorities, regulators, water companies and defence and scientific establishments. Typical samples include soils, building materials, asbestos, oils, waters, metals, solvents, biota, vegetation, milk and sea life.

Our experienced, multi-skilled team of radiochemists and dedicated project managers will design analysis programmes to meet your schedules, expectations and budget. They also offer consultancy support, training, and research and development services.

We operate a quality system to the requirements of BS EN ISO 17025:2005 for our analytical and testing services, which has been assessed by UKAS. We are a UKAS accredited laboratory (no.1011) and the scope of accreditation applies to specific test procedures listed in the laboratory’s schedule of accreditation. In 2019, the laboratory is transitioning to BS EN ISO 17025:2015 accreditation with support from UKAS.
