Following up this article.. Tepco been mis-analyzing Strontium-90 in contaminated water and seawater for 2.5 years since 311 [URL]


The analysis data of Strontium-90 are not straightly announced to public, according to Tepco.

Last week, Tepco finally admitted their Strontium-90 analysis was wrong, and released some of the data that have been concealed for over 6 months.

However, still none of the recent data is published. Since last June, approx only a few tens of Strontium-90 data have been published.


Strontium-90 analysis is known to take 1 month, but they haven’t announced for way over 1 month.

As to the reason, Tepco’s spokesman commented they take time to “check” the analysis data, in the press conference of 2/10/2014.

They state the manager of radiation measurement department of Fukushima headquarters checks “if it’s credible enough to publish”. The manager is supposed to send the report to the headquarters in Tokyo for approval.

There is a possibility that Tepco censors the raw analysis data before release.

Tepco :  “Les résultats des analyses sont contrôlées par quelqu’un chargé de voir s’ils sont publiables”

Article lié : A partir de mars 2011 et pendant 2 ans et demi Tepco a donné des résultats faux sur le strontium 90

Les données des analyses du strontium 90 ne sont pas directement rendues publiques, selon Tepco.
La semaine dernière, Tepco a enfin reconnu que leurs analyses du strontium 90 étaient fausses et a publié quelques données qui ont été censurées pendant plus de 6 mois.
Néanmoins, aucun résultat récent n’est publié. Depuis juin dernier, seulement une petite dizaine de résultats sur le strontium 90 ont été publiés.

On sait que les analyses du strontium 90 prennent environ un mois à faire mais ils n’en ont rien dit pendant bien plus qu’un mois.
Pour le justifier, le porte-parole de Tepco a déclaré au cours de la conférence de presse du 10 janvier 2014 qu’ils prenaient le temps de “contrôler” les données des analyses.
Ils affirment que le patron du service de mesure de la radioactivité du siège de Fukushima contrôle “si c’est assez crédible pour être publié”. Ce patron est supposé envoyer le rapport au siège de Tokyo pour validation.
Il est donc possible que Tepco censure les données de base avant publication.

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.
