Tritium and Sr-90 detected outside of Fukushima nuclear plant port

According to Tepco, Tritium and Strontium-90 were detected in the outside of Fukushima nuclear plant port.

The sampling date was 7/15/2013. The analysis result hasn’t been published for over a month.

The readings are 5,500 Bq/m3 of Tritium and 1,200 Bq/m3 of Strontium-90.

These were detected in the north side of reactor5&6 water outlet.

From the sampling of 8/19/2013, all β nuclides (including Sr-90) was lower than the detectable amount. Tritium density was 4,700 Bq/m3 on 8/12/2013.

The radiation level in the seawater is increasing regardless of the impervious walls, and apparently it’s spreading out of the port.

Du tritium et du strontium à l’extérieur du port de la centrale nucléaire de Fukushima


Selon Tepco, du tritium et du strontium 90 ont été relevés à l’extérieur du port de la centrale nucléaire de Fukushima.

La date d’échantillonnage est le 15 juillet 2013. Les résultats d’analyse n’ont pas été publiés pendant plus d’un mois.
Le relevé est de 5 500 Bq/m³ de tritium et de 1 200 Bq/m³ de strontium 90.
Ils ont été relevés au nord du déversoir des réacteurs 1-6.
Dans les échantillons du 19 août 2013, les β-nucléides (dont le Sr 90) étaient inférieurs au minimum détectable. La radioactivité en tritium était de 4 700 Bq/m³ au 12 août 2013.
La radioactivité de l’eau de mer augmente malgré les murs “étanches” et se répand apparemment au-delà du port.

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.
