Although the destruction of entire towns over an area stretching for 500 kilometers to the north and south is of an almost unimaginable scale, we believe that this immense devastation can be overcome and we hope that during the process of rebuilding the disaster-affected region, we can also discover a path for the future of Japan and the world. The earthquake has also brought the new crisis of radioactive contamination to Japan.

Not only is there the physical issue of the cleanup following the nuclear accident, but one of the first steps on the path to recovery must be to reduce the negative image which people have of Japan as a country contaminated by nuclear radiation, and thereby lessen the damage to Japanese industry, by presenting the world with an objective look at the current situation – at least within a range that is reasonable to modern science. _lnnwq4NhNw1qzfnm5o1_1280.jpg (925×1280) 国・自治体による高さ1m・0.5m計測を中心とした放射線量マップ Radiation dose measured by MEXT and local governments at 1 or 0.5 meter height.

Unfortunately the data was also somewhat unhelpfully stuck in PDF format. However between us Gemma Hobson, Pete Warden and I transcribed, mostly by hand, some of the more helpfully formatted files into CSV format (16KB) making it acceptable to Pete's OpenHeatMap service.
