Breaking News: 100 million cubic meter amount of soil

The amount of the contaminated soil that would result from decontaminating the land within Fukushima Prefecture that has been contaminated by radioactive materials by the Fukushima Daiichi Nuclear Power plant’s accident can reach the approximate maximum of 100 million cubic meters, according to an estimate made by Prof. Yuuichi Moriguchi of Tokyo University (Environmental System Engineering).

The scale of it is said to be about a total remaining capacity for a general waste of all landfills in the nation combined. The assumption was made for decontaminating the areas with the radiation level of 1 microSv/hr and above in air.

1 microSv/hr and above is the standard criterion for the government’s assistance in order to replace the contaminated surface soil of school yard. Analyzing by using the data from the Ministry of Education, Culture, Sports, Science and Technology, etc., the areas that exceed this standard extends to about 2,000 square kilometers that includes Planned Evacuation and Buffer Zones.

However,”fresh” radiation falls down daily, by every minute, 1 billion cubic meter will be increase but will never decrease.

In a rough estimation,if it takes 40 years to settle down the situation,8 billion cubic meter amount of contaminated soil will be produced in total.

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.
