A study, published in January 1997 in the British Medical Journal by two French scientists, showed a potential link between an increased incidence of childhood leukemia in the area around La Hague and discharges from the plant. Dominique Pobel and Jean-Francois Viel conducted a case-control study, covering a 35-kilometer radius around the plant.
