Strontium-90 detected from seawater of Fukushima plant port in 95% of the tests

Strontium-90 was measured from most of the areas in Fukushima plant port from January to March. 2014.


On 7/25/2014, Tepco released the report about Strontium-90 analysis of seawater to reveal that they had measured Strontium-90 in most of the seawater samples taken from Fukushima plant port from January to March.


The sampling areas are in front of Reactor 1~4, inside and the exit of the port, and outside of the port.

Strontium-90 was detected from 40 of 42 measurements. The measurement point outside of the port was only beside Reactor5&6 water outlet (cf, Reactor5&6 pump up 6,000 tones of seawater per hour from Fukushima port to discharge to outside of the port [URL]), however 17 ~ 690 Bq/m3 of Sr-90 was detected at that point.


Sr-90 was detected in the exit of the port from February to March. The highest reading was 1,000 Bq/m3. They didn’t analyze seawater around the port exit, but there is a possibility that they tried to conceal Sr-90 data spreading out of the port.


The highest reading was 400,000 Bq/m3 measured in the North part of Reactor 1~4 water intake.

Du strontium 90 dans 95 % des échantillons d’eau du port de la centrale de Fukushima


Entre janvier et mars dernier, le strontium 90 a été relevé dans pratiquement tous les endroits du port de la centrale de Fukushima.

Le 25 juillet 2014, Tepco publie un rapport sur ses analyses du strontium 90 dans l’eau de mer qui révèle qu’ils ont relevé du strontium 90 dans la plupart des échantillons pris dans le port de la centrale.

Les endroits échantillonnés sont en face des réacteurs 1 à 4, dans le port et à sa sortie et en dehors du port.
Le strontium 90 a été relevé dans 40 des 42 analyses. Le seul point relevé à l’extérieur du port a été à côté du déversoir des réacteurs 5 & 6 (cf. Les réacteurs 5 & 6 pompent dans le port de Fukushima 6 000 tonnes d’eau de mer par heure et les déversent en-dehors du port), il y avait néanmoins entre 17 et 690 Bq/m³ de Sr 90 à cet endroit.

De février à mars, du Sr 90 a été relevé à la sortie du port. Le record en a été de 1 000 Bq/m³. Ils n’ont pas analysé l’eau de mer des alentours de la sortie du port mais il est probable qu’ils essayent de cacher les données de la contamination de l’extérieur du port.

Le record a été de 400 000 Bq/m³ au nord de la prise d’eau des réacteurs 1 à 4.

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.
