TOKYO – Two years have passed since the Fukushima nuclear accident, and international interest in its impact is beginning to wane. But that impact continues to reverberate – and not only in global public debate about the future of nuclear energy. More than a hundred thousand people remain displaced by the accident, some having lost family, homes, possessions, and even the desire to live.
Japan’s nuclear industry, regulators, and government have a responsibility to explain clearly why science and technology could not minimize the risk and consequences of such an accident in a geologically vulnerable country like Japan; why unreasonably costly cleanup is being carried out in areas of low contamination, where negligible impact on public health is anticipated; and why no well-defined and operational waste-management system has been established. The lessons learned may help not only to reduce the risk of future accidents, but also to facilitate recovery in areas around the world that have been contaminated by radioactive or other toxic substances.
Japan has a strong international reputation when it comes to managing natural disasters. But the “perfect storm” of the largest earthquake and tsunami since industrialization, and the resulting meltdown of three reactor cores at the Fukushima Daiichi plant, went beyond any scenario previously envisaged. Japan’s national government and local communities had no emergency plan for the situation that they faced in the contaminated areas, resulting in ad hoc responses marked by inefficiency and poor communication, particularly with regard to radiological risk.
