Tepco estimated that the cesium emission of January is 70 million Bq/h, but it increased to be 72 million Bq/h even since 1/23, when they made the estimation. The radiation leakage is in the increasing trend.
From 1/22 ~ 1/28, emission of cesium per hour was 72 million Bq/h, Tepco announced. It increased from December by 12 million Bq/h. However, this is only the leakage amount from reactor 1,2 and 3. The leakage data from reactor 4 is not published.
Tepco explains it is because they started woking in reactor 2 and 3, more people walk about so the dust flies into the air. They add, it is really difficult to reduce the emission drastically.
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.
