Health risk assessment from the nuclear accident after the 2011 Great East Japan Earthquake and Tsunami based on a preliminary dose estimation

This report summarizes the results of a health risk assessment from the nuclear accident that followed the 2011 Great East Japan Earthquake. The assessment was conducted by a group of independent experts convened by WHO and the report represents the first international effort to estimate radiation risks from this accident at the global level.

The primary purpose of this health risk assessment is to estimate its potential public health impact so that future health needs can be anticipated and public health actions can be taken. This assessment is based on a preliminary estimate of radiation doses. The report is primarily intended for use by policy makers and health professionals in WHO member states, as well as by international organizations.

Finally, it should be noted that this report discusses health risks rather than health effects. It is not intended to provide estimates of the disease burden in the population or to calculate possible excess disease cases due to the radiation exposure resulting from this accident.
