In legal practice, CRCE refers to the former Centre for
radiation, Chemical and Environmental Hazards, whose scientific guidance and risk assessments are routinely cited in environmental, health and safety, nuclear and planning matters. The term is not defined in legislation; it was the institutional title within the Health Protection Agency and later Public Health England. Since 2021 its functions have been carried out within the UK Health Security Agency (UKHSA), typically via the Radiation, Chemical and Environmental Hazards Directorate.
Practitioners rely on CRCE/UKHSA publications and expert advice when interpreting and evidencing compliance under the Ionising Radiations Regulations 2017 (IRR17), the Radiation (Emergency Preparedness and Public Information) Regulations 2019 (REPPIR), Environmental Permitting Regulations, radon management duties, contaminated land (Part 2A, Environmental Protection Act 1990), chemical incident response, and non‑ionising radiation (EMF) exposure. CRCE/UKHSA material is frequently referenced in due diligence, environmental impact assessment, public inquiries and litigation as an authoritative source.
Usage is broadly consistent across England & Wales, Scotland and Northern Ireland (with UKHSA working alongside devolved bodies such as Public Health Scotland, SEPA and the Public Health Agency NI). In Ireland, “CRCE” is not used; equivalent regulatory science and guidance are provided by the Environmental Protection Agency (including the former RPII)...
