The Japanese government is trying to calm fears about radiation levels and food safety in the region around the heavily damaged Fukushima Daiichi nuclear power facility, even as it has raised the severity rating of the crisis to the highest possible level. "Radiation is continuing to leak out of the reactors, the situation is not stable at all," says Dr. Michio Kaku, professor of theoretical physics at the City University Of New York and the City College of New York, in an interview on Democracy Now! April 13. "The slightest disturbance could set off a full scale melt down at three nuclear power stations - far beyond what we saw at Chernobyl."
