10 μSv/h from a container to ship to Taiwan / Honmoku pier in Yokohama

4.5 ~ 10 μSv/h was measured from a container on 4/13/2014. It was to be shipped from Honmoku pier to Taiwan, but it is not announced what is specifically in the container.   The employee of Japan Post Holdings detected the radiation level over 5 μSv/h before loading, which is higher than the safety limit [...]

Someone turned on 4 irrelevant pumps / 203t of 37,000,000,000 Bq/m3 contaminated water transferred to wrong place

203 m3 of highly contaminated water was transferred to the wrong plant buildings. Cs-134/137 density was 37,000,000,000 Bq/m3 in the wrongly transferred water.   The basement floors of reactor1~4 retain the coolant water and groundwater that increase by 400 m3 per day. Both of them are highly contaminated. Tepco pumps it up and reuse it [...]

1 m3 of contaminated water leaked again / “Did someone make a hole on the tank for malicious purpose again ?”

1m3 of contaminated water leaked from another contaminated water tank. Tepco announced the leakage has already been stopped because all the water has gone out.   It was a 1m3 plastic tank beside 1,000m3 class of tanks. It is not explained why the tank was left there. A sub-contract worker found the tank was empty [...]

M4.9 Fukushima offshore / Tepco reported the quake in Fukushima plant was fortunately 1/6 “slower” than Daini

M4.9 hit Fukushima offshore at 18:16 of 4/13/2014 (JST) according to Japan Meteorological Agency. The maximum seismic intensity was 4 in Naraha machi. The depth of epicenter was 60km.   Tepco announced there was no abnormality in plant parameter, and they also reported that the Gal (unit of gravitational acceleration) monitored in Fukushima Dai-ichi plant [...]

[Column] The most important thing in the time of hazard

Since 311, I’ve been hearing a lot of people say ” you should put this and that to an emergency bag or everyday bag at least. ” etc.. Yes, passport, wallet, phone charger,, these would help you accordingly in emergency. However from my personal experience, what you really need to protect is “your life”. That’s [...]

“Like a garbage house” / Tepco’s spokesman “Storage cabinet is too messed to track the past samples”

Following up this article.. [Tepco's upward revision] “80 BILLION was actually 280 BILLION Bq/m3 in last summer’s leakage” [URL]   The storage cabinet of contaminated water samples is not properly managed, remains like a “garbage house”, Tepco’s spokesman talked on 4/11/2014.   Regarding 300 m3 leakage of contaminated water, Tepco revised the radioactive density from [...]

[Tepco's upward revision] “80 BILLION was actually 280 BILLION Bq/m3 in last summer’s leakage”

Following up this article.. Leaked all β of “300m3 leakage accident” was also underestimated / INES level might be increased [URL]   All β nuclide density was 280,000,000,000 Bq/m3 in the leaked tank water last summer. All β nuclide means the collective of the nuclides to include Strontium-90. Tepco announced the all β nuclide density [...]

[Video column] Fukushima Diary talks “Tepco washing off Plutonium to the Pacific, huge risk for the least effect”

Tepco plans to start discharging the bypass water to the Pacific from this coming June, but alpha nuclides including Plutonium-238/239/240 and Uranium-235/238 will not be tested nor filtered. It would decrease only 10~25% of the groundwater flowing to the plant buildings, but why do they have to take such a risk ? When they finish [...]

Tepco started pumping up the bypass water to discharge / Tritium density jumped up to 87% of desired safety level

↑ The groundwater bypass wells     ↑ The tanks to stock pumped water before discharging     Following up this article.. Tepco NOT to analyze Plutonium or Uranium in bypass water before discharging to the Pacific [URL]   Tepco started pumping up the groundwater from the bypass wells on 4/9/2014. They have already stocked [...]
