Easy to understand radiation map


This is a new radiation map of Cs-137, which is summed up from March, April and May.

(Mega Bq / km2)

This is based on the data from Ministry of Education, Culture, Sports, Science and Technology, so obviously it is less than actual. It also misses Cs-134, Strontium, Uranium and Plutonium etc.

However, we could at least see where is worse than where, where is better than where.

Even if you don’t read Japanese, I guess numbers of Cesium-137 help you enough.


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.
