A professional video of Marco Kaltofen's presentation to the American Public Health Association was recently made available to Fairewinds. Kaltofen states that hot particles are contaminating portions of northern Japan. He also states that auto air filters from Fukushima, that he tested in his Massachusetts laboratory, are so radioactive that they have to be disposed of in a buried radioactive waste disposal site in the US. Additionally, he expresses concerns for the mechanics who work on cars in Fukushima Prefecture.
