Marine contamination reached Philippines last April

Kobayashi fellow-researcher from Japan Atomic Energy Agency analyzed that 18,000 trillion Bq of Iodine 131 and cesium 134 + 137 directly leaked from Fukushima to Pacific ocean.
However, because it is the estimation after 3/26, it would be much more than that if it includes what leaked from 3/11 to 3/25.
Also, it will be a several times much as 18,000 trillion Bq to count the radiation to fall from air down to the sea.
From their simulation, marine contamination already reached Philippines by 4/10/2011, will reach Hawaii by March of 2014, where is 5300 km away from Fukushima.

東京電力福島第一原子力発電所から放出された海の放射能汚染水は、2014年3月には薄まりつつ日本から約5300キロ離れたハワイ諸島近くに到達することが日本原子力研究開発機構のシミュレーション結果でわかった。海水から受ける被曝(ひばく)量は低いという。

原子力機構の小林卓也研究副主幹らが原発の放水口付近の海洋での放射能の実測値などをもとに、昨年3月26日以降に直接海に流出した放射能量を推定した。これとは別に、大気から降下した放射能量もシミュレーションで推定した。

試算によると、福島第一原発から海へ直接放出された汚染水の放射能量は放射性のヨウ素とセシウム合わせて計1京8千兆ベクレルに上るという。

さらに大気から海に降り注いだ放射性物質を含めると数倍に増えるという。海に漏れた汚染水は、薄まりつつ海流に運ばれ、14年3月には、ハワイ諸島沖に最大で海水1リットルあたり約0.04ベクレルのセシウム137を含む水が到達する予測になった。小林さんは「この時に最高濃度のセシウムを取り込んだ海産物を1年間毎日食べても、内部被曝は0.001ミリシーベルトほどにとどまる」と話した。(杉本崇)

 

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.
