Consequent to the Great East Japan Earthquake and ensuing tsunami on March 11, 2011, huge amounts of radioactive particles were released into the air. 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 a region contaminated with radioactive particles, to this day, we Japanese are not consciously aware of the radiation.

In this App, dozens of radiographic images of plants created by Satoshi Mori, Professor emeritus, Tokyo University since 2011 are on display together with radiographic images of everyday items and animals. This collection of radiographic images (autoradiographs) is the first in history to be created by radiation resulting from a nuclear accident. I hope that viewers will come away with a sense of the extent of contamination in all regions subject to the fallout… not just those limited to Fukushima.
