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.
Cs-134 : 750,000,000,000 Bq/m3
Cs-137 : 1,600,000,000,000 Bq/m3
This is only a part of the entire trench. It is not announced how much contaminated water is retained in total.

2,35 Tera Bq/m³ de Cs-134/137 côté mer de la tranchée du réacteur 2
 
Ce 27 juillet 2013, Tepco annonce qu’ils ont relevé 2 350 000 000 000 Bq/m³ dans les eaux retenues côté mer de la tranchée du réacteur 2.
C’est la tranchée de la prise du câble électrique du réacteur 2. Le 19 juillet 2013, Tepco avait foré un trou (de 20 cm de diamètre) dans cette tranchée à partir de sa surface. Ils ont pris l’échantillon le 26 juillet 2013.
Le 19 juillet 2013, le Fukushima Diary publiait “36 milliards de Bq/m³ de Cs-134/137 dans les eaux retenues dans la tranchée du réacteur 2 / le tritium en cours d’analyse ” Cette fois, c’est dans la tranchée voisine.
Au bilan, ils ont relevé un niveau extrêmement élevé de radioactivité :
Cs-134 : 750 000 000 000 Bq/m³ (750 milliards)
Cs-137 : 1 600 000 000 000 Bq/m³ (1 600 milliards)
Ce n’est que dans une portion de la tranchée. Ils ne donnent pas la quantité totale d’eau retenue dedans.
