Background: The Japan earthquake and tsunami of 11 March 2011 severely damaged the Fukushima Daiichi nuclear plant. After learning of the radiation leak, the Japanese government issued an evacuation directive for residents within 20 km of the plant a day after the earthquake. Approximately 1 month later, this area was designated a 'high alert zone' and effectively sealed-off. The purpose of this report is to examine these measures from an ethical perspective, and consider what lessons can be drawn from this experience.
Methods: Analytic discussion.
Results: We examine the measures from an ethical perspective and argue that if the government's aim was to avoid health risks posed by radiation exposure, then ordering compulsory expulsion of all residents cannot be ethically justified. We assert that the government may not have ordered the mandatory evacuation solely based on health risks, but rather to maintain public order.
Conclusion: Careful scrutiny of the case revealed that this public health intervention involved an objective completely unrelated to public health, and that disguising these policies using the reasonable and acceptable purpose of public health made it easier to justify undue restriction of individual liberty.
