Introduction by Eiichiro Ochiai
More than five years have elapsed since the great earthquake and the accompanying huge tsunami (on 3.11 of 2011), and its subsequent disaster at the Fukushima Dai-ichi Nuclear Power Plant of the Tokyo Electric Power Co. Three nuclear reactors there underwent explosions and another, though without explosion, was highly damaged. A large amount of radioactive material has been and is still being released as a result of the accidents.
Aside from the very difficult issues of how to deal with the melted nuclear fuel rods and with the increasing amount of contaminated water, people all over Japan, particularly those in Fukushima prefecture, are concerned with the effects of radiation on human health from the released radioactive material.
One disease, childhood thyroid cancer, has been recognized even by the authorities including the International Atomic Energy Agency (IAEA) and International Commission of Radiation Protection (ICRP), as the result of radiation released by the 1986 Chernobyl disaster in today’s Ukraine. Hence Fukushima Prefecture initiated a health survey of Fukushima citizens, including evacuees, that included scanning for thyroid abnormalities of all children under age 18 at the time of the accidents. It turned out that a large number of children have contracted thyroid cancers over the last five years: 172 out of ca. 380,000 children by the end of 2015. The majority of them have undergone surgery, and many have been found to have metastasized. This number , and the annual rate per 1,000,000, ca 90, is unusually high, compared with the rate 1 to 3 per 1,000,000 under normal circumstances.
The Fukushima prefectural government and the organization charged with conducting the examination are trying to rationalize the results in many ways, without invoking the radiation impact of the reactor meltdowns. If this is indeed unrelated to the radiation from the damaged Fukushima Nuclear Power Plants, a similarly high rate of thyroid cancer should be found all over Japan. ....
