[1,900 Bq/m3] Sr-90 measured from Fukushima plant offshore seawater, Tepco admitted it’s due to the accident

According to Tepco, Sr-90 was measured from seawater around Fukushima nuclear plant.

The highest reading was 1,900 Bq/m3 from North of reactor 5-6 Discharge Channel. The sample was taken on 3/11/2013.

They also measured 42 Bq/m3 of Sr-90 from 3km offshore Fukushima nuclear plant. (Upper layer) The sampling date was 3/5/2013.

About these measurements, Tepco commented below to admit it is due to Fukushima Accident.

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.

[1 900 Bq/m³] Du strontium 90 dans l’eau du large de la centrale de Fukushima, Tepco admet que c’est à cause de l’accident

 

Selon Tepco, du Sr 90 a été relevé dans l’eau de mer autour de la centrale nucléaire de Fukushima.

Le record en a été de 1 900 Bq/m³ au nord du déversoir des réacteurs 5 et 6. L’échantillon est du 11 mars 2013.
Ils ont aussi relevé 42 Bq/m³ de Sr 90 à 3 km au large de la centrale nucléaire de Fukushima (couche supérieure). L’échantillon est du 5 mars 2013.
Sur ces relevés, la déclaration de Tepco ci-dessous admet que c’est à cause de l’accident de Fukushima :

Bien que du Sr-90 ait été relevé soi-disant en conséquence de cet accident, il y en a moins que la limite de concentration dans l’eau, ce qui est précisé sur cet avis.

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.
