Preliminary dose estimation from the nuclear accident after the 2011 Great East Japan Earthquake and Tsunami
The earthquake and tsunami in Japan on 11 March 2011 led to releases of radioactive material into the environment from the Fukushima Daiichi nuclear site. This report describes a preliminary estimate of radiation doses to the public resulting from this accident. These doses are assessed for different age groups in locations around the world, using assumptions described in the report.
The dose assessment forms one part of the overall health risk assessment being carried out by WHO of the global impact of the accident at the Fukushima Daiichi nuclear power plant. The health risk assessment is the subject of a separate WHO report published in February 2013.
