Monitoring post closest to reactor4 “malfunctioned”→Back up post “malfunctioned”→40 mins of “recording blank”

One of the monitoring posts malfunctioned on 4/4/2014, according to Tepco. The monitoring post is to measure the radiation level on the plant area border, where is the closest to reactor4.

They switched it to the back up post, however it malfunctioned as well. Tepco ended up sending a human worker to measure the radiation level, however they missed the record of the radiation level for 40 minutes.


When the human worker started measuring the radiation level, the dose level was 2.5 μSv/h, which is the same as just before the monitoring post malfunctioned, Tepco announced.

Tepco stated the monitoring post went back on about one hour later, however the cause isn’t announced. It is unknown what happened during the “missing” 40 mins.



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.

La borne de surveillance la plus proche du réacteur 4 a “mal fonctionné”→ la borne de secours a “mal fonctionné”→40 mins “vierges d’enregistrement”


Selon Tepco, une des bornes de surveillance a mal fonctionné le 4 avril 2014. Les bornes de surveillance relèvent la radioactivité ambiante aux limites de la centrale, celle-ci est la plus proche du réacteur 4.
Ils ont basculé sur la borne de secours mais elle a mal fonctionné aussi. Tepco a fini par envoyer un ouvrier pour relever le niveau de radioactivité, néanmoins ils n’ont pas pu enregistrer la radioactivité pendant 40 minutes.

Tepco a déclaré que quand le travailleur a commencé ses mesures, la radioactivité ambiante était à 2,5 μSv/h, soit la même chose que ce qu’il y avait juste avant que la borne commence à mal fonctionner.
Tepco affirme que la borne de surveillance a été remise en marche environ une heure plus tard, néanmoins la cause de la panne n’est pas communiquée. On ne sait pas ce qui s’est passé pendant les 40 mins “manquantes”.

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.
