IRSN, L'Institut de Radioprotection et de Sûreté Nucléaire or the French Institute for Radiological Protection and Nuclear Safety, had an animation of Fukushima radioactive plume dispersion model on their site: http://www.irsn.fr/FR/popup/Pages/irsn-meteo-france_19mars.aspx
FRCSR turned the animation into hourly still images, uploading the images from March 12 through 20 here, along with the timeline notation of the explosions which occurred at Fukushima Dai-ichi.

This might be helpful in recognizing how much fallout people might have experienced, depending on where they were at the time when the fallout came to their areas of residence.
