13,299 Bq/Kg from home-grown rosemary in Kashiwa

It’s very difficult to judge what to eat, what not to eat in Japan. Radiation measurement of local governments and supermarkets may not be trustworthy. However, it seems like we must avoid home-grown products at least.


13,299 Bq/Kg of cesium was measured from rosemary in Kashiwa.

A media writer, Chidai conducted radiation measurement of rosemary, grown in the garden of Kashiwa Chiba. Kashiwa is about 200km from Fukushima plant, known to be a hotspot.

The sample was taken by the person who found the highly radioactive yellow substance. (cf. 180,000 Bq/Kg from the yellow substance in Kashiwa Chiba) It is from early summer of 2011.

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.
