Consequent to the Great East Japan Earthquake and ensuing tsunami on March 11, 2011, the cores of the first to third nuclear reactors at the Fukushima Daiichi Nuclear Plant melted down because external power for the cooling water pumps was lost. As a result, huge amounts of radioactive particles were released into the air.

Whether we are in Tokyo, in Fukushima Prefecture, or even if we are standing in front of the nuclear reactor buildings whose cores melted down, and that were severely damaged by hydrogen explosions, we are unaware of the presence of radiation…it is too small to see; it cannot be heard; and it is odorless. Therefore, despite living in region contaminated with radioactive particles, to this day, we are not consciously aware of the radiation. Thus, I believe that the radioactive contamination has to be perceived visibly and with the cooperation of Satoshi Mori, Professor Emeritus at the University of Tokyo, I am using autoradiography to make radioactive contamination visible.
