Radiation emit has increased since January

 

Tepco announced reactor 1, 2 and 3 emit 70 million Bq/h in January, which has increased since November and December by 10 million Bq/h. *1

Increased amount

Reactor 1 : +2 million Bq/h
Reactor 2 : +10 million Bq/h
Reactor 3 : +10 million Bq/h
Total : +22 million Bq/h *2

Emission

Reactor 1 : 20 million Bq/h
Reactor 2+3 : 50 million Bq/h
Total : 70 million Bq/h

 

Tepco announced that is because they operated to see inside of reactor 2 by endoscope but there is no explanation why it increased at reactor 1 and 3 as well. They have not mentioned the influence of the earthquake started from 1/1/2012.

*1,2 : The original article of Yomiuri made a mistake. They stated the total emission of November and December was 60 million, but the total increasing amount has to be 22 million. Yomiuri is known to be a pro-nuclear mass media.

東京電力は23日、福島第一原子力発電所1~3号機から放出される放射性物質について、毎時約7000万ベクレルという最新値を発表した。
11、12月の同6000万ベクレルより増えた。東電は、2号機の格納容器内を内視鏡で観察する作業などに伴い、原子炉建屋内の放射性物質が舞い上げられたのが原因と見ている。

号機別では、建屋にカバーを設置している1号機が毎時200万ベクレル。2号機と3号機が同約1000万ベクレルずつ増え、それぞれ同2000万ベクレル、同5000万ベクレルだった。追加放出による敷地境界の被曝線量は年間0・12ミリ・シーベルトと推定している。

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.
