[Concealment ?] Fukushima prefecture deleted the emergency radiation monitoring data of when reactor1 exploded


Fukushima prefecture deleted the emergency monitoring data at 5km from Fukushima plant.
The portable monitor recorded the radiation level from 5AM to afternoon of 3/12/2011, when reactor1 exploded.
Fukushima prefectural government comments because they couldn’t output the recorded data, they deleted it when they used the monitor in the different location in 9. 2011.
However, the maker states they can output the data by connecting to PC.

It was installed in the shelter of Ohkuma junior high school, where 100 people evacuated, but because they deleted the data, it can’t be evaluated how much those people were exposed.

The disaster headquarters of Fukushima prefectural government comments the recorded and deleted radiation data didn’t show any difference from ordinary levels, and they were busy.

On the other hand, they monitored the increase of radiation level at 10km area from 5AM 3/12/2011.

[Censure ?] La préfecture de Fukushima efface les données de surveillance d’urgence de la radioactivité au moment où le réacteur 1 explosait


La préfecture de Fukushima a effacé les données de surveillance d’urgence de la radioactivité à 5 km de la centrale de Fukushima.
Le 12 mars 2011, le portable avait enregistré les niveaux de radioactivité à partir de 05:00 jusqu’à l’après-midi, quand le réacteur avait explosé.
Les autorités de Fukushima disent que c’est parce qu’ils ne pouvaient pas extraire les données enregistrées, qu’ils les ont détruites lorsqu’ils l’ont utilisé ailleurs en septembre 2011.
Cependant, le fabricant dit qu’ils peuvent en extraire les données en le connectant à un PC.

Il était installé dans le refuge de la junior high school d’Ohkuma où 100 personnes avaient évacué mais, parce qu’ils ont effacé les données, on ne peut évaluer à quel point ces gens ont été irradiés.

Le quartier générale de la catastrophe de la préfecture de Fukushima déclare que les données enregistrées et détruites ne présentaient aucune différence avec les niveaux habituels et ils étaient actifs.

D’un autre côté, ce 12 mars 2011 et à partir de 05:00, ils ont suivi l’augmentation de la radioactivité dans une zone à 10 km.


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.
