Leading scientists and engineers gathered in Oxfordshire to debate the controversial issue of radioactive discharges into the environment.

Stan Gordelier, UKAEA director, Dr Kevin Langley, BNES chairman, and Roy Manning, UKAEA secretary.

More than 100 of Europe's top nuclear industry experts attended a two-day conference at Harwell International Business Centre on gaseous and liquid radioactive discharges.

Dr Langley said: "Natural radioactivity from non-nuclear operations such as fertiliser production or oil extraction, which is vastly greater than discharges from nuclear sites, is ignored."
