I-131 is still measured from dried sewage sludge in Chiba

Iodine 131 was measured from dried sewage sludge by Chiba prefectural government again. Iodine 131 is the nuclide to cause thyroid cancer or thyroid related disease. You are to take Iodine table after nuclear accident but now it’s already too late.

The half life time of iodine 131 is only 8 days, and it is produced from nuclear fission. It makes us question, “Has nuclear fission really ended in Fukushima?”

Iodine 131 is also used for medical treatment, but high level of Iodine 131 has been measured from various places. We need to verify where it keeps coming from.

(cf. 4,800 Bq/Kg of iodine 131 was measured in Tokyo

570 Bq/Kg of Iodine 131 was measured in Gunma

Iodine 131 measured in Kawasaki, Yokohama, Chiba and Gunma

Iodine 131 measured in Yamanashi  and more..[Link])


Sample 1

Sample taken 7/20/2012

217 km from Fukushima plant

Iodine 131 : 25 Bq/Kg


Sample 2

Sample taken 7/18/2012

219 km from Fukushima plant

Iodine 131 : 13 Bq/Kg

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.
