We point out serious inconsistencies of the first paper of the series, written by Makoto Miyazaki and Ryugo Hayano, which discusses the correlation between the personal doses of the citizens of Date City measured by glass badges with the ambient dose rates measured by six airborne surveys. The last of the six airborne survey was made in the period of 2014 Q3 (from October 2014 to December 2014). The real number of participants of the period is about 14,500; however, in Table 1 2014 Q3 it is…

TLDR
A method for estimating effective doses based on the available ambient dose rate survey data could aid in the prediction of individual doses in the early phase of future radiological accidents involving large-scale contamination.

TLDR
Estimating the lifetime doses of the Date City residents, based on continuous glass badge monitoring data, extrapolated by means of the ambient-dose-rate reduction function obtained from the airborne monitoring data found that the external exposure contribution to the mean additional lifetime dose of residents living in Date City is not expected to exceed 18 mSv.
