 note = {—It has been challenging to obtain reliable estimates of
thyroid equivalent doses (TEDs) to residents involved in the 11
March 2011 Fukushima Daiichi Nuclear Power Plant (FDNPP)
accident because of the shortage of direct human measurements
associated with 131I, the largest contributor to the dose of concern.
The present study attempted to perform the estimation of the
TEDs by inhalation of 131I to residents from Namie-town, one of
the most radiologically-affected municipalities, by means of the
latest atmospheric transport and dispersion model (ATDM) simulations with the Worldwide version of System for Prediction of Environmental Emergency Dose Information (WSPEEDI) ver. 2,
coupled with personal behavioral data containing the history of
the whereabouts of individuals shortly after the accident. We analyzed 1,637 residents who underwent direct measurements with
whole-body counters several months after the accident and provided their personal behavioral data. We divided the subjects into
two groups based on whether the distances between their locations
and the FDNPP were >20 km as of 15:00 on 12 March in relation
to the timepoint of the hydrogen explosion at the Unit 1 Reactor
building. As a result, the 90th percentile TEDs of the 1,249 prompt
evacuees and 388 late evacuees were 3.9 mSv (adult)–6.8 mSv
(10-y-old) and 24.1 mSv (adult)–35.6 mSv (5-y-old), respectively,
excluding 16 persons whose TEDs exceeded 50 mSv. The 90th percentile (median) TEDs to 1-y-old children (not included in the subjects) for the prompt and late evacuation groups were 8.1 (1.0) mSv
and 36.3 (19.7) mSv, respectively. Additionally, this study provided
the evidence to support the view that the explosive event at the Unit
1 Reactor building on the afternoon of 12 March 2011 could have
caused the critical group among Namie-town's residents, whereas
the largest release event on 15 March gave relatively small doses to
the residents because their exposure took place mostly at sites that
were distant from the FDNPP. However, the present dose estimation
has potentially large uncertainty at the individual level; further
validations are thus necessary.},
