FUKUSHIMA — A prefectural panel of experts here concluded on June 3 that thyroid cancer diagnosed in a second round of prefecture-wide checks in fiscal 2014 and 2015 on people who were aged 18 and under at the time of the meltdowns at the Fukushima Daiichi Nuclear Power Station in March 2011 was unrelated to their exposure to radiation emanating from the disaster.
However, as individual exposure doses were not measured and there is no data on those who have yet to be examined, panel members emphasized that its conclusions are provisional. Gen Suzuki, the head of the panel, said, “We haven’t concluded that there are no long-term effects from radiation.” He pointed to the need to continue thyroid cancer screenings for the time being while informing the children and their guardians of the demerits of overdiagnosis.
Following fine adjustments to the content of the report, its conclusions will be presented to an executive examination committee.
The second round of screenings, held in the fourth and fifth years after the onset of the nuclear disaster, is essential for judging the potential effects of the nuclear disaster and were carried out on some 380,000 people. Of those, 71 people were suspected to have some form of the cancer, with at least 52 of them receiving operations for the condition.
