Breaking News: 276,000 Bq/Kg soil from Chiba


Following up this post,

The exact location and the contamination level was revealed by the city government.

According to their report,they took 3 samples:

Sample 1 (Ground soil)

  • Cs-134 70,200 Bq/Kg
  • Cs-137 85,100 Bq/Kg
  • Total 155,300 Bq/Kg

Sample2 (30cm deep in the ground)

  • Cs-134 87,000 Bq/Kg
  • Cs-137 105,000 Bq/Kg
  • Total 192,000 Bq/Kg

Sample3 (30cm deep in the ground)

  • Cs-134 124,000 Bq/Kg
  • Cs-137 152,000 Bq/Kg
  • Total 276,000 Bq/Kg

By Gamma ray spectrometer

They covered the spot with soil (50cm) and waterproof sheet.

They announce there is no problem anymore because the radiation level at 10m distance is the same as the radiation at other places, which is 0.3 microSv/h. This is another problem itself.

Because it contains Cs-134, it is obviously from Fukushima,and also because it’s higher underground ,probably “someone” (or some government) secretly abandoned radioactive waste/soil into the area and covered.

Before 311,you were forbidden to take out 4 Bq/Kg of radioactive material out of a lab.You had to make a written apology.
276,000 Bq/kg deserves 69,000 written apologies.


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.
