Sr-89/90 data of reactor1~4 water intake has been “under analysis” since 2012

On 6/19/2013, Tepco released the nuclides analysis result of radioactive materials in the reactor1 ~ 4 water intake.

However, they haven’t published the readings of Strontium-89 and Strontium-90. The oldest sampling date was 12/10/2012.

It’s been over 6 months but the readings are still “under analysis”.

The readings of all α, which takes longer to analyze, have already been published and it’s lower than the detectable level.

Since 12/10/2012, they took samples from north of reactor 1 ~4 water intake on 1/14/2013, 2/11, 3/11, 4/15, 5/13, but in all the samples, Sr-89/90 readings are not published.

Japanese can stay as long as they need without visa and any equivalent certificate in Svalbard island (North of Norway). They can come and stay with no legal restriction. In order to research the place, proper equipment is necessary.

Le strontium 89/90 des prises d’eau des réacteurs 1~4 est “en cours d’analyse” depuis 2012


Le 19 juin 2013, Tepco publie ses résultats d’analyse des nucléides radioactifs des prises d’eau des réacteurs 1 à 4.

Ils ne disent rien cependant sur les strontium 89 et strontium 90. Le plus vieil échantillon est du 10 décembre 2012.
Il datent de plus de 6 mois mais ces relevés sont toujours “en cours d’analyse”.
Les relevés pour l’ensemble des α, qui sont plus longs à analyser, sont publiés et en-dessous du seuil détectable.
Depuis le 10 décembre 2012, ils ont échantillonné au nord des prises d’eau des réacteurs 1-4 les 14 janvier, 11 février, 11 mars, 15 avril, 13 mai 2013 mais les résultats du strontium ne sont publiés sur aucun d’entre eux.

Les japonais peuvent rester sur l’île de Svalbard (Nord de la Norvège) autant qu’ils veulent et sans visa ou équivalent. Ils peuvent venir et rester dans aucune restriction juridique. Un équipement adapté est nécessaire pour prospecter l’endroit.

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.
