On 9 August 2012, the scientific journal Nature published on its website a scientific article revealing physiological and genetic damage in several generations of a butterfly population in the vicinity of the Fukushima Daiichi nuclear power plant (“The biological impacts of the Fukushima nuclear accident on the pale grass blue butterfly”). In the weeks following its publication, the article was given considerable coverage in the French and international press.
IRSN's laboratories are involved in several scientific collaborations with Japanese universities and scientific organisations focusing on the environmental impact of the Fukushima accident. The Institute's science watch team also focuses on important scientific publications on this subject. Within this context, it has produced an analysis of the article on mutations observed in a butterfly species.
