私は日本の小児科医です。2011 年 の福島原発事故以降、それまでの日本の罹患率の 50

よる見せかけの多発であるというのが権威筋の公式見解です。私はこの評価に疑問を持ち、

I am a Japanese pediatrician. Since the Fukushima nuclear accident in 2011,
childhood thyroid cancer has been occurring in Fukushima Prefecture more than 50
times the prevalence in Japan. The official view of the authoritative source is that it
appears to be frequently caused by S creening ef fects or O ver diagnosis. Me and my
collaborators questioned this assessment and examined the dose response relationship
between thyroid cancer detection rate and exposure dose in 59 municipalities in
Fukushima Prefecture per person year. The detection rate in the area divided into 10 in
order of the dos e at 1710 locations of UNSCEAR MEXT measurement clearly showed a
significant Poisson regression with the dose. Detection Rate Ratio μ Sv/h) = 1.555
Reference; Medicine (Baltimore) .2019 Sep; 98 (37): e17165. This paper indicates that
following the paper by Dr. Tsuda et al., Thyroid cancer in Fukushima was also proven
to be damaged under low dose radiation following Ch ernobyl. In view of this fact, We
think that it is a big mistake from a scientific point of view that the ICRP, which should
be at the foref ront of radiation protection, will make changes that will lo osen its defense
standards. I am against this revision.
