Radioactive material from Fukushima plant coming back to Japan in the Pacific

Prof. Aoyama from Institute of Environmental Radioactivity of Fukushima University reported that the radioactive material discharged from Fukushima plant circulated in the Pacific to come back to Japan offshore.

He implemented seawater analysis at 71 points from 11. 2015 to 2. 2016. The analysis is partially completed to show radioactive material has spread to the South West offshore of Japan. 2 Bq/m3 of Cs-137 was detected in seawater from South West offshore of Kyushu. 1.83 Bq/m3 was detected even offshore of the west coast of Japan.

0.38 Bq/m3 of Cs-134 was also measured to prove this is from Fukushima accident.

It is assumed that the discharged Cs-134/137 travelled to the east in the Northern Pacific. It was carried to the South and West to come back to Japan by taking 2 ~ 3 years.

He comments it is possible that the density of radioactive material increases from now.

Dans le Pacifique, la radioactivité de la centrale de Fukushima revient sur le Japon

 

Le Pr. Aoyama de l’Institut de Radioactivité Environnementale de l’Université de  Fukushima déclare que la radioactivité déversée par la centrale de Fukushima dans le Pacifique en a fait le tour pour revenir au large du Japon.

Il a procédé à des analyses de l’eau de mer en 71 points entre novembre 2015 et février 2016. Ces analyses sont partiellement terminées et montrent que la radioactivité s’est répandue au large du Sud-Ouest du Japon. Ils ont relevé 2 Bq/m³ de Cs-137 dans l’eau de mer au Sud-ouest de Kyushu. Ils ont même eu 1,83 Bq/m³ au large de la côte Ouest du Japon.
0,38 Bq/m³ de Cs-134 ont aussi été isolés prouvant qu’il s’agit bien de la catastrophe de Fukushima.
On pense que les Cs-134/137 déversés ont voyagé vers l’Est dans le Pacifique Nord. Ils ont ensuite, pendant 2 à 3 ans, été transportés vers le Sud puis l’Ouest pour revenir au Japon.

Il déclare possible que la radioactivité se mette à augmenter à partir de maintenant.

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.
