Breaking news ; 610,000Bq/m3 of Sr-89 was measured in Tokyo, 3/18/2011

Though Japanese government have been denying the presence of Strontium and Plutonium around Tokyo,

US government (DOE and NNSA) had already measured air in Tokyo From March to April.

It shows that massive amount of Strontium has already fell on Tokyo.The max is 610,472Bq/m3 at Meguro.

Although,because this is in m3,it’s a little difficult to compare it with the contamination in Chernobyl ,which is mostly in m2 or km2.

They also knew neptunium 239 is out of the plant.

4,040Bq/m3 at

The table below is to show how much Sr-89 and 90 were in the air in Tokyo from March to April.

If you didn’t wear a mask,you definitely breathed it . Only god knows.

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.
