UNSCEAR 2013 Report (2/9)
Outline of Assessment of Public Exposure Doses
As indicated in the preface to the Report, at its fifty-eighth session in May 2011, the UNSCEAR decided to carry out, once sufficient information was available, an assessment of the levels of exposure and radiation risks attributable to the nuclear power plant accident following the Great East-Japan Earthquake and tsunami of March 2011. It was decided to mainly utilize prefectural data and government organizations' data released in Japan up to September 2012, and other data and documents provided by UN member countries other than Japan and by international organizations such as the International Atomic Energy Agency (IAEA) and the WHO. Additionally, new important information obtained by the end of 2013 was also taken into consideration to the extent possible.
"Chapter IV Assessment of doses to the public" of the UNSCEAR Report comprises the following.
A. Exposure pathways, B. Data for dose assessment, C. Overview of methodology for assessing public exposures, D. Results of dose estimation, E. Uncertainties, and F. Comparison with direct measurements and other assessments
"D. Results of dose estimation" shows the estimation results for effective doses and absorbed doses in specific organs for general public in Japan. The section consists of (i) doses in the first year for members of the public not evacuated, (ii) evacuees' doses, (iii) estimation of doses in Japan for exposure over future years, and (iv) estimation of doses in other countries.
Details of the estimation of public exposure doses will be explained in the following pages.
