Japanese government published their prediction that some areas will remain more radioactive than 20mSv/y even in 10 years, where will still be uninhabitable on 4/22/2012.
They are planning to complete decontamination in places where the radiation level is lower than 50mSv/y by March of 2014. However, they still have not made a plan for the areas where the radiation level is higher than 50mSv/y.
Though it is assumed that some of the evacuated people want to go home even if it takes time, Japanese government is inclined to the idea that spending money on supporting evacuating people is more efficient. It costs significant sum of money to decontaminate and the reliable technology is not established. It would be more efficient to spend the money on evacuating people.
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.
