Abstract
On 11 March, 2011 a magnitude 9.0 earthquake struck off the North-eastern coast of the Japanese main island of Honshu. Although reactors at the Fukushima Daiichi Nuclear Power Plant shut down as expected, the 15m tsunami which followed caused a loss of power which disrupted the cooling systems. Over the next few days, four of the six reactors experienced catastrophic events, requiring the evacuation of plant personnel and residents of nearby villages in a 20km radius. Nuclear contamination has continued to hinder clean-up and reconstruction efforts in Fukushima prefecture, one of the three worst hit by the tsunami, and it is estimated that the plant itself could take up to 40 years to decommission. Moreover, subsequent investigations have revealed serious systemic issues in the regulation of nuclear power and in the mechanisms for provision of scientific advice to the public, policymakers, and to disaster response personnel, which has contributed to a considerable loss of public trust in both scientists and the Japanese government. Handling of the ‘triple disaster’, therefore, raises important questions for understanding the scale and extent of nuclear contamination after accidental release, but also about the need for realistic emergency planning and for consistency, accuracy and trust in the dissemination of useful information, not only during an unfolding disaster and immediate recovery period, but often for years, even decades, to come
