They measured strontium at 3 locations in Tokyo (one is at METI)

Sample taken: 10/6/2011
Analysis: 10/26/2011
Lab: A private laboratory
Sample: 500g from each (30cm×30cm×5cm)

1) In front of Ministry of Economy, Trade and Industry

  • Sr-89,90: 48 Bq/Kg
  • Cs-137: 26,826 Bq
  • Cs-134: 21,350 Bq

A shrubbery near the tent of the recent Fukushima Mothers protest, where these mothers had been abused by local police and violent right wing criminals, and where these mothers stood up against the incompetent Japanese Government.

It was 1.38 Micro Sv/h. (The person in the tent told, it has been 3.00 Micro Sv/h)



2) Near Kiyosumi Shirakawa station

  • Sr-89,90 : 44 Bq/ Kg
  • Cs-137: 10,502 Bq
  • Cs-134: 8,624 Bq

A shrubbery about 2~3 mins by walking from the station.
It was about 0.60 ~ 0.74 Micro Sv/h.



3) Near Yurakucho station

  • Sr-89,90: 51 Bq/Kg
  • Cs-137:11,545 Bq
  • Cs-134: 9,410 Bq

A shrubbery in front of the station.
It was about 0.60 Micro Sv/h.



These locations were picked up randomly.
Strontium can be scattered everywhere in Tokyo.
The person who measured them says, wind and rain gather hot particles.
They roll and gather so they keep making new hot spots all the time.

Also, when they took the soil sample,they dig the ground by 5cm, but radiation level did not decreased more than half.
Self-proclaimed Japanese government talks us they can decontaminate by digging the ground, but this survey proved it is not effective.

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.
