Distribution of radiocesium and dose estimation studies related to Fukushima Daiichi nuclear power plant accident

This paper will briefly mention the doses summarized by the UNSCEAR report. In addition, this paper will review some information including articles or official announcements not cited in the UNSCEAR report. Topics of the information were categorized as follows: (1) thyroid dose estimation by simulation and simultaneous measurement of indoor and outdoor radionuclide concentrations (2) internal dose: whole-body counting results in Fukushima Prefecture and caesium intake estimation by food analysis, and (3) external dose. Radiation monitoring data as well as radiation education should be one of the input bases for adequate and effective risk management
