20,201 Bq/Kg and 14,531 Bq/Kg of cesium was measured from the dust of vacuum.
The former one was taken in Nagareyama Chiba, the later one was taken in Ibaraki.
Co-op Joso and National Institute for environmental studies measured dusts in vacuum cleaner in 257 houses of South Ibaraki and North-West Chiba, where are known to be hotspot.
The measurement was done in April 2012.
As a result, they measured 1,956 Bq/Kg of cesium from the dusts in vacuum cleaner at average.
The highest reading was 20,201 Bq/Kg and the second highest reading was 14,531 Bq/Kg, which are beyond the safety limit of 8,000 Bq/Kg, which is allowed to fill land as incineration ash.
According to the study of Pathological anatomist, Yury Bandazhevsky from Belarus, 90% of the children in Homyel to have 37 – 74Bq/kg of cesium measured from their cardiac muscle showed abnormal electrocardiogram.
Highly concentrated cesium in dust causes serious internal exposure to breathe in.
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.
