Thyroid Ultrasound Examination: Order of Full-scale Survey
The Thyroid Ultrasound Examination has been conducted sequentially, starting in areas where ambient dose rates were higher at the time of the accident at Tokyo Electric Power Company (TEPCO)'s Fukushima Daiichi NPS.
For Full-scale Surveys following the Preliminary Baseline Survey, notices of the examination have been sent mostly in the same order.
Since the Full-scale Survey (fourth-round survey), the examination has been conducted mostly in the same order for those aged 18 or younger. However, for those aged 19 or older, the examination has been conducted not by region but by age (school year). In FY2018, those born in FY1996 (aged 22) and born in FY1998 (aged 20) were examined, and in FY2019, those born in FY1997 (aged 22) and born in FY1999 (aged 20) were examined.
Since FY2017, the examination has been conducted for those who become 25 years old in the relevant year, and then once every five years thereafter.
Due to the impact of the COVID-19 pandemic, the Full-scale Survey (fifth-round survey) was decided to be carried out in three years. As originally planned, notices of the examination were sent to examination targets living outside Fukushima Prefecture in FY2020 and FY2021, and the examination may be received until the end of FY2022.
