Radiation from the Chernobyl and Fukushima nuclear accidents may not have been as harmful to wildlife as previously thought. New research by Professor Jim Smith, of the University of Portsmouth, and colleagues from the University of the West of England has cast doubt on earlier studies on the impact on birds of the catastrophic nuclear accident at Chernobyl in April 1986. Until now, scientists had thought radiation had a dramatic effect on bird populations following the Chernobyl disaster because it had caused damage to birds’ antioxidant defence mechanisms. But Professor Smith and colleagues have, for the first time, quantified this effect. Their study modelled the production of free radicals from radiation, concluding that the birds’ antioxidant mechanisms could easily cope with radiation at density levels similar to those seen at Chernobyl and Fukushima.
