Preliminary Dose Estimation from the Nuclear Accident after the 2011 Great East Japan Earthquake and Tsunami

Next steps

Q12. What happens next?

The Dose Assessment Report forms one part of an overall health risk assessment (to be published in summer 2012) by WHO of the global impact of the accident at the Fukushima Daiichi NPP. The Health Risk Assessment Report will contain an analysis of estimated health risks resulting from the Fukushima NPP accident, and if deemed appropriate, will provide guidance on long-term health surveillance programmes, including screening and epidemiological follow-up to support the most exposed populations.

Further protective measures and remedial actions have been undertaken in Japan to reduce radiation exposure. These actions together with improved datasets will enable further refined dose estimations in the future.

The Fukushima prefecture initiated the Fukushima Health Survey that includes a ‘record of movement’ of residents from the time of the accident in March 2011 onwards. This initiative will provide information of individual dose assessments, and will assist in the implementation of health surveillance programs.
