When Fukushima 1 Nuclear Power Plant (NPP) was torn apart by several explosions, whether due to technical failings in correspondence with the earthquakes, tsunami or a combination of both, it not only dispersed radioactive contaminant but also exposed the bonds connecting people's lives with nuclear power. Over the two and a half years since then, the corruption, inadequacies and mendacities at the centre of the sovereign power structure that has prevailed in Japan since 1945 have become ever more visible. This essay first introduces the foundations of this structure, exploring how the long-standing relationship between Government and major private electric utilities in Japan informs the present crisis, noting in particular the ramifications of decisions being made within this structure at the individual level in present and projected effects to human health. Following consideration of the effects of radiation on human health, the discussion then turns to visual and local testimonies of the effects of other radiological events - Hanford, Hiroshima and Nagasaki, Chernobyl and Iraq - so as to offer a comparative assessment of the Fukushima disaster. While mindful of the difficulty in arriving at an absolutely conclusive position on these conditions, enough evidence has now accumulated to make a realistic assessment of the human health impact, and to discern how public understanding has been, and continues to be, confused. Finally, given that the Fukushima disaster is distinguishable from other radiological events in scale and type of contamination, this essay argues that far-reaching change is called-for in the current legal standards and institutional responses which have been governed thus far by mid twentieth century power relations.
