March of radioactive pollen

In Japan, pollen come fly to Tokyo from December to April.

The peak is from February to April.

Next year, radioactive pollen is assumed to fly to Tokyo.

Currently Ministry of Agriculture, Forestry and Fisheries is surveying, but it’s being too slow, as expected.

They measure how much Cs-134 and Cs-137 are contained in the leaves but have no clue how to estimate how much of them move to pollen.

However, it’s reported that the Japanese cedar leaves are already seriously contaminated.

Kawamata machi, Fukushima
177,600 Bq/Kg

Otama mura, Fukushima
11,700 Bq/Kg

Because pollen get into the eyes, ears, and also attached to the skin, hair, and clothes, a mask is not enough – at all.


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.
