What is the danger to people on the West Coast?
"The short answer is, essentially none. There is no such thing as zero risk, but the risk from the radiation from Japan is orders of magnitude from being dangerous, by any definition," says epidemiologist Kirk Smith, a professor of global environmental health in UC Berkeley’s School of Public Health, is an expert on the health effects of radiation exposure, such as that from nuclear waste, nuclear power plant accidents and radon in households.

UC Berkeley's Department of Nuclear Engineering continues to collect air samples for any sign of radiation. On Friday, they also collected rain to see if any radioactive particles fell from the sky.
"The rain is a very efficient way to wash out activity in the atmosphere and get the potential activity down to us. So this is actually a much more sensitive and efficient way for sampling," Professor Professor Kai Vetter from the UC Berkeley Department of Nuclear Engineering said. Read more.
