| Outline of Final Research Achievements |
This study regarding thyroid examinations conducted among children and young people after the Fukushima nuclear power plant accident revealed that thyroid examinations have a negative impact on the mental health of the subjects and residents, that overdiagnosis of thyroid cancer occurs even among children and young people, and that people undergo examinations without knowing of the harms of overdiagnosis. These findings highlight the ethical issues involved in the thyroid examination. Based on the findings of this study, we proposed the following: (1) the examination should be done on an opt-in basis and be voluntary, (2) information about the examination should be provided, sufficient explanation of the harms of overdiagnosis, and (3) the method of examination, including the criteria, should be reviewed to curb overdiagnosis.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は原発事故と言う災害下で現在進行形でおこなわれている調査・研究が、住民にどのような影響を与えているかを多面的に解析し、負の影響があることや調査・研究のあり方に倫理的課題があることを指摘し、さらに甲状腺検査のよりよい方法論を提案したことに大きな社会的意義がある。さらに成人では甲状腺癌スクリーニングが過剰診断をもたらすことに加え、小児や若年者においても同様の現象が生じることを、その自然史とともに報告したことに学術的意義がある。
