Tepco detected nearly 7 Trillion (10^12) Bq/m3 of All β nuclides from contaminated water in the summer of 2013

Tepco had measured approx. 7 Trillion (10^12) Bq/m3 of All β nuclides from contaminated water last summer, but they underestimated it to be 1/10 due to the “wrong analysis” according to Tepco.

On 2/24/2014, Tepco released the detailed list of 167 wrongly analyzed samples (and they stated 3 of them were correctly analyzed). (cf, Tepco mis-analyzed 167 samples since 311/ Correct readings can be over 10 times much as wrong ones [URL 2] )


From their report, 6 of them exceeded 100 Billion Bq/m3 in All β nuclides even based on the wrong analysis. These are the contaminated water samples taken from underground trenches of reactor2 and reactor3.

Tepco comments the wrong analysis underestimated the readings by 1/10. It means the highest reading would be 6.7 Trillion Bq/m3, which is the water taken from reactor3 trench pit.

The sampling date was about 2 months before IOC selected Tokyo as the host city of Olympic games in 2020.





Downplay it in the beginning, and quietly add more information so nobody notices it. All for not letting the cattle escape. This is their strategy.

Sur l’été 2013, Tepco a relevé près de 7 trilliards (= 7 000 milliards) de Bq/m³ de radioactivité β dans les eaux contaminées

Tepco a relevé environ 7 trilliards  (10^12) de Bq/m³ de radioactivité β dans les eaux extrêmement radioactives l’été dernier mais ils l’ont sous-estimé à son dixième (1/10) à cause des “analyses faussées”, selon Tepco.

Le 24 février 2014, Tepco a publié une liste précise des 167 échantillons mal analysés (et ils affirment que 3 d’entre eux ont été correctement analysés). (cf. Tepco a mal analysé 167 échantillons depuis le 11-3 : les relevés corrects peuvent être plus de 10 fois supérieurs aux erronés)

Selon leur rapport, 6 d’entre eux dépassent les 100 milliards de Bq/m³ de radioactivité β même en se basant sur les analyses faussées. Il s’agit d’échantillons d’eau pris dans les tranchées souterraines des réacteurs 2 et 3.
Tepco déclare que les analyses faussées ont sous-estimé les relevés à leur dixième (1/10). Ça signifie que le relevé record était autour de 6,7 trilliards (= milliers de milliards) de Bq/m³, pris dans le trou de la tranchée du réacteur 2.
L’échantillon datait d’environ 2 mois avant que le CIO sélectionne Tokyo comme ville des jeux olympiques de 2020.


Le minimiser au début et ajouter tranquillement de nouvelles information pour que personne ne le remarque. Tout pour que le troupeau ne s’échappe pas. C’est leur stratégie.

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.
