Japan Times is one of the many newspapers to carry this Kyodo report on "three young people have thyroid cancer". The fact of the matter is:
A Fukushima Prefectural Government panel said Wednesday that two people who were 18 or younger when the triple-meltdown crisis started at the Fukushima No. 1 atomic complex in March 2011 have been diagnosed with thyroid cancer, bringing the total cases to three.
Kyodo also reports that a professor on the panel said:
Reporting at a meeting on the health impact from the catastrophe, professor Shinichi Suzuki of Fukushima Medical University said it is too early to link the cases to the nuclear disaster, because it took at least four to five years for thyroid cancer to be detected after the Chernobyl meltdown calamity that started in 1986.
However, if we look what might be the Japanese version of the Kyodo story on Yahoo! via the Mainichi, we see:
That’s quite a different emphasis. However the same professor also said this:
Surely the prof would have an exact figure, rather than passing on "one in a million"? A comment on Japan Times provides a link to UK child data, so taking the 15 to 19 year old band, it is about sixteen in a million. However, scaling up the tests in Fukushima, 3 in 38,000, we get about eighty in a million. This is about five times higher than the expected UK rate, but if we stick with three people instead of perhaps zero or one people in an "average" year, the change may be either an expected statistical fluctuation (I don’t know the maths to do to demonstrate that!) or caused just by the increase in thyroid tests.
It’s also interesting to note that there has already been 43 retweets of this article, many of them the usual anti-nuclear crowd.
