Minister of Nuclear disaster, Hosono stated, they will make a researching team to study “low” dose symptom.
They raised the max limit of annual exposure in Japan from 1 mSv to 20 mSv.
However, nobody knows what it means.
There is no reliable scientific data to show how 20m Sv/y affects our human body.
They raised the limit without knowing any potential risk only to keep the shape of Japanese nation.
They will study how it affects our human body by using us as sample.
We are the human guinea pig.
