Health risk assessment from the nuclear accident after the 2011 Great East Japan earthquake and tsunami, based on a preliminary dose estimation

The earthquake and tsunami in Japan on 11 March 2011 led to releases of radioactive material into the environment from the Fukushima Daiichi nuclear power plant. This health risk assessment is intended to give an indication of the potential public health implications of the accident to support the identification of needs and priorities for public health actions. This report, based on a preliminary dose estimation published by WHO in May 2012, represents the first international effort to assess the radiation health risks from this accident at the global level.
