Scientist Marco Kaltofen Presents Data Confirming Hot Particles
Today Scientist Marco Kaltofen of Worchester Polytechnic Institute (WPI) presented his analysis of radioactive isotopic releases from the Fukushima accidents at the annual meeting of the American Public Health Association (APHA). Mr. Kaltofen’s analysis confirms the detection of hot particles in the US and the extensive airborne and ground contamination in northern Japan due to the four nuclear power plant accidents at TEPCO’s Fukushima reactors.
Fairewinds believes that this is a personal health issue in Japan and a public health issue in the United States and Canada.
