Merger of BNFL, UKAEA and AWE Worker Epidemiology Studies into NRRW

UKHSA has published guidance on the planned merger of three separate nuclear-sector epidemiological cohorts — BNFL (approximately 42,000 radiation workers), UKAEA (approximately 75,000 radiation workers), and AWE (approximately 9,000 radiation workers) — into the National Registry for Radiation Workers (NRRW). The NRRW, established in 1975, is a national health surveillance registry for UK radiation workers. The merger aims to increase statistical power for radiation-risk research, enable internal-dose calculations for approximately 30,000 workers with bioassay data, and create a non-radiation worker comparison group to control for the healthy worker effect. Administrative efficiencies include reduced data-entry duplication, streamlined information governance, and improved data security through a single database. An NHS research ethics committee issued a favourable opinion in May 2021 (REC reference 21/SC/0063).

National Registry for Radiation Workers Guidance

UKHSA publishes guidance on the National Registry for Radiation Workers (NRRW), an epidemiological study established in 1976 to monitor health effects of long-term low-dose occupational exposure to ionising radiation among UK workers. The registry links occupational radiation exposure data with mortality and cancer incidence records to assess whether radiation protection regulations provide adequate protection for workers. The study currently holds records on over 270,000 workers from nuclear power generation, Ministry of Defence, British Nuclear Fuels Ltd, and UK Atomic Energy Authority sites.
