2,200,000,000,000 Bq/m3 of All β was measured seaside trench of Reactor2 last year/ Tepco underrated 1/3× for a year
Last July, Fukushima Diary posted..
On 7/27/2013, Tepco announced they measured 2,350,000,000,000 Bq/m3 from retained water of seaside trench of reactor2.
It’s water intake power cable trench from reactor2. Tepco opened a hole (20cm diameter) on the trench from the ground on 7/19/2013. They took the sample on 7/26/2013.
On 7/19/2013, Fukushima Diary reported “36,000,000,000 Bq/m3 of Cs-134/137 measured from retained water of reactor2 trench / Tritium density under analysis [URL]” This time, they investigated the next trench.
As a result, extremely high level of radioactive material was detected.
This is only a part of the entire trench. It is not announced how much contaminated water is retained in total.

On 6/20/2014, Tepco corrected the reading of All β nuclides density (Including Strontium-90) of this water.
The water was sampled on 7/26/2013, and they measured 2,350,000,000,000 Bq/m3 of Cs-134/137 as reported above.
The newly announced All β nuclide density is 2,200,000,000,000 Bq/m3. In July of 2013, Tepco announced it was 750,000,000,000 Bq/m3, which is 1/3 of what they announced now. The underrated reading has been published for 1 year.
Tepco states they mis-analyzed because the density was too high.
(cf, Tepco aware of wrong analysis by 7/24/2013 / 2 days after they officially admitted contamination leaking to the sea [URL])
Le 20 juin 2014, Tepco corrige son relevé en radioactivité β (dont le strontium 90) pour cette eau.
L’eau avait été échantillonnée le 26 juillet 2013 et ils avaient relevé 2 350 000 000 000 (2,35 mille milliards de) Bq/m³ de Cs 134/137 comme rapporté ci-dessus.
La nouvelle radioactivité β est de 2 200 000 000 000 (2,2 mille milliards de) Bq/m³. En juillet 2013, Tepco avait dit 750 000 000 000 (750 milliards de) Bq/m3, soit le tiers de ce qu’ils annoncent à présent. La sous-estimation est restée publiée un an.

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.
