Strontium-90 detected at 2 locations in 3km offshore Fukushima nuclear plant

According to Tepco, Strontium-90 was detected at 2 locations in the Pacific.

17 Bq/m3 at 3km offshore of Ukedo river.

35 Bq/m3 at 3km offshore of Fukushima daini nuclear plant.

 

The sampling dates are early April of 2013.

About this measurement, Tepco commented, “Although Sr-90 was detected supposedly as a result of this accident, it is less than the density limit in the water which is specified by the announcement.”.

However, the samples are taken from only upper layer of the sea.

According to the research of “Meteorological Research Institute”, at least Cs-134/137 were observed sinking deeper in the Pacific due to the subduction of winter.

(cf, Meteorological Research Institute, “Cs-134/137 going deeper under ocean due to the subduction of winter” [URL])

Du strontium 90 détecté en deux endroits à 3 km au large de la centrale nucléaire de Fukushima

 

Selon Tepco, du strontium 90 a été relevé en 2 points dans le Pacifique :

17 Bq/m³ à 3 km au large de l’embouchure du fleuve Ukedo.
35 Bq/m³ à 3 km au large de la centrale nucléaire de Fukushima Daini.

Les échantillons datent de début avril 2013.
Sur ces relevés, Tepco déclare : “Bien que du Sr 90 ait été relevé soi-disant à cause de cet accident, c’est en quantité inférieure à la limite dans l’eau qui est spécifiée par l’avis”.
Les échantillons n’ont cependant été pris que dans la couche superficielle de l’océan.
Selon les recherches du “Meteorological Research Institute“, on a observé au moins du Cs 134/137 s’enfonçant plus profondément dans le Pacifique à cause de la subduction hivernale. (cf. Lien)

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.
