Cesium from tuna fished in west coast of America

On 5/28/2012, researching team of Stanford university published cesium was measured from Bluefin tuna of American west coast on Proceedings of the National Academy of Sciences of the United States of America.

It was from 15 bluefin tuna fished last August. 4Bq/kg of cesium 134 and 6.3Bq/kg of cesium 137 were measured, which is clearly from Fukushima plants.
They assume those bluefin tuna were near Japan when 311 happened and moved to the west coast of America with ocean currents.

 

米国沖のマグロから微量セシウム 原発事故の影響と発表

東京電力福島第1原発事故に伴う微量の放射性セシウムが、米西海岸沖のクロマグロから検出されたと米スタンフォード大などの研究チームが28日付の米科学アカデミー紀要電子版に発表した。

チームは「マグロが太平洋を横断し、原発事故による放射性物質を運んできたのは明らかだ」としている。食べても健康への影響は心配ないレベルだが、事故の大きさをあらためて示す結果だ。

昨年8月、カリフォルニア州沖でクロマグロ15匹を捕獲、セシウム134を1キログラム当たり4ベクレル、セシウム137を6・3ベクレル検出した。昨年の原発事故時に日本沿岸にいて海流に乗り移動してきたらしい。

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.
