Following up this article ..Fukushima fall-out spiked up again
The reason why fall-out level spiked up in the beginning of this year might be from incineration of radioactive garbage and debris, Prof. Takeda Kunihiko from Chubu University talks.
Fukushima local government explains it was because of the strong wind, but statistically, fall-out level decreases on a windy day either.
Also, the date of when reactor 4 had problems does not match when the fall-out level increased.
Prof. Takeda says the fall-out increase is linked to the incineration date, and the radiation level emit from incineration plants is not published by the government.
