He picked up 1,175 of his patients ,whose thyroids have been stable, with no change / stop of medication, and analyzed the change of a thyroid hormone “Free T4” and thyroid stimulation hormone for 3 months after 3/11.
As a result, 939 (80%) of the patients had Free T4 decreased and thyroid stimulation hormone increased to cover up the decrease of Free T4 .
These patients did not take excessive amount of Iodine ,pregnancy ,bearing ,hay fever for the testing term of the 3 months.
Before 3/11: 1.37
After 3/11: 0.92
Thyroid stimulation hormone
Before 3/11: 1.5
After 3/11: 5.2
Dr.Miyashita says, it does not necessarily cause thyroid cancer ,but he has never seen such a change before. Though he does not know the dose level of those patients but continuous observation is needed.
Decrease of Free T4 causes fatigue.
About this site
This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
