260 Bq/m3 of Sr-90 measured in 30m north of reactor5, 6 discharge channel

According to Tepco, Strontium-90 was detected from the marine environment outside of Fukushima nuclear plant.

The samples were taken May of 2013. The locations and readings are below,

3km offshore of Fukushima nuclear plant : 13 Bq/m3

30m north of reactor5 and 6 discharge channel : 260 Bq/m3

1.3km south of reactor1~4 discharge channel : 220 Bq/m3

 

Tepco admitted the connection between the detection and Fukushima accident, but doesn’t consider it to be a problem to take countermeasures.

They reported this below,

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.

Do you know why this is not on TV ?

260 Bq/m³ de strontium 90 à 30 m au nord du déversoir des réacteurs 5 et 6

 

Selon Tepco, du strontium 90 a été relevé dans l’environnement marin à l’extérieur de la centrale nucléaire de Fukushima.

Les échantillons ont été pris en mai 2013. Les lieux et valeurs sont les suivants :
A 3 km au large de la centrale nucléaire de Fukushima : 13 Bq/m³
A 30 m au nord du déversoir des réacteurs 5 et 6 : 260 Bq/m³
A 1,3 km au sud du déversoir des réacteurs 1 à 4 : 220 Bq/m³

Tepco admet le lien entre ces détections et l’accident de Fukushima mais ne les considère pas comme un problème nécessitant un traitement.

Ils le rapportent ainsi :

Bien que le Sr 90 ait été sans doute détecté en conséquence de cet accident, il est en-deçà de la limite de concentration dans l’eau, ce qui est précisé dans ce communiqué.

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.
