MEXT admitted Strontium90 was measured in Tokyo and 9 other prefectures
Japanese government has started to admit the actual contamination situation because of Fukushima little by little.
On 7/24/2012, Ministry of Education, Culture, Sports, Science and Technology published the data of strontium90. This measured has been done since before 311 monthly. The published data was taken from 4.2010 to 12.2011.
It’s been reported that strontium90 from Fukushima was measured in Fukushima and Miyagi. This data reported it was measured in 10 other prefectures as well,
MEXT states the highest reading was 6 Bq/m2 in Hitachinaka city Ibaraki, which was taken in 3.2011.
It was 1/2850 of cesium supposedly, which is harmless for health.
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.
