[Sea contamination] Cesium in Pacific cod is increasing offshore Hokkaido

Octopus from Fukushima was sold for the first time since 311, however, other countries like South Korea is making the import regulation more strict than ever for the concern about spreading sea contamination. (cf. South Korea banned import of additional 35 types of marine products)

Actually, sea contamination is spreading to offshore Hokkaido.

Agricultural department of Hokkaido government published the latest report about cesium contamination of Pacific cod.

The research was started last August, but the average cesium amount of July.2012 was the highest except for the data of August.2011. Cesium contamination is in the increasing trend after the drop in this spring.

Through the research, the highest reading was 70 Bq/Kg (Cs-134 31 Bq/Kg, Cs-137 39 Bq/Kg) from the sample taken 1/8/2012, but the second highest reading was 68 Bq/Kg (Cs-134 26 Bq/Kg, Cs-137 42 Bq/Kg) from the sample taken 7/25/2012.

Both of the samples were taken from Pacific ocean side. This suggests the contamination spread in Pacific ocean.

  1. FUKUSHIMA DIARY FR – [contamination marine] le césium augmente dans les morues du Pacifique au large d’Hokkaido.
    Par Mochizuki, le 2 août 2012.

    Le poulpe de Fukushima a été vendu pour la première fois depuis le 11-3, alors que d’autres pays comme la Corée du Sud renforcent plus que jamais leurs régulations à l’importation dans un souci de limiter la diffusion de la contamination marine. (cf. South Korea banned import of additional 35 types of marine products – http://fukushima-diary.com/2012/08/south-korea-banned-import-of-additional-35-types-of-marine-products/)

    De fait, la contamination marine augmente au large d’Hokkaido.

    Le département de l’Agriculture d’Hokkaido publie son dernier rapport sur la contamination au césium de la morue du Pacifique.

    La recherche a commencé en août dernier mais la quantité moyenne de césium de juillet 2012 est la plus forte depuis août 2011. La contamination au césium est en augmentation après le recul de ce printemps.


    Selon cette recherche, le plus haut relevé a été de 70 Bq/Kg (Cs-134 31 Bq/Kg, Cs-137 39 Bq/Kg) sur un échantillon pris le 1/8/2012 et la seconde plus haute mesure de 68 Bq/Kg (Cs-134 26 Bq/Kg, Cs-137 42 Bq/Kg) sur un échantillon du 25/72012.

    Les deux échantillons proviennent de l’océan Pacifique. Ceci suggère que la contamination diffuse dans l’océan Pacifique.

  2. This is so sad. So sad! A country that loves seafood has poisoned a large part of its ocean. My husband and children are Japanese, I am broken-hearted for everyone. 🙁

  3. People worldwide are now beginning to understand what radioactive lack of containment means.

    If the Japanese government does not stop these radioactive leaks in their entirety, without the lies and subterfuge, the rest of the world will abandon Japan.

    Everyone has to remember that Japan has been harassed and incarcerated before before due to racist/nationalist issues. The Fukushima plant was designed by General Electric, an AMERICAN corporation.

    So before citizens of other countries start pointing fingers and saying the Japanese citizens should suffer because their government is corrupt, they’d better remember that Obama,the President of the U.S., has known for a year, let the radioactivity get to the West Coast of America without intervening.

    America, China, Japan, France, Russia and the UK already know that Fukushima is out of control. Don’t let the politicians turn citizens away from each other.

    It is the GOVERNMENT’S fault this happened-not the citizens.

    Remember that.

    1. But this is always the way it’s been………divide and conquer. Therefore there has to be voices like yours and mine, to educate and spread the word far and wide. WE DO NOT WANT NUCLEAR POWER, NUCLEAR ENERGY, NUCLEAR WEAPONS. And, though i voted for Barack Obama, i KNEW things were not going to change because CAPITALISM RULES. Not the people, not the voices of many people. Corporations rule, in America and most other places in the world.

      1. I neglected to express my concern and sorrow for the people of Japan, and as the disaster spreads, to those people who swim in the waters (Pacific) and who breath the air and to those who are in areas where nuclear power plants reside who may suffer the way the residents of Fukushima have suffered.

        I will do as much as i can to stop the spread of these disasters waiting to happen.

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.
