On West Coast of U.S., much ado about very little radiation, so far
03/19/11 Los Angeles Times — U.S. scientists and sensors are poised to detect radioactive fallout from Japan's nuclear accident, but aside from a 'minuscule' amount at a Sacramento station, they've found none. The nuclear engineering department at UC Berkeley set up its own independent monitoring Wednesday on top of the campus' Etcheverry Hall. The system looks for gamma rays with energy "signatures" corresponding to radioactive isotopes, said Kai Vetter, a professor in the department. As of Friday morning, Vetter said, they hadn't seen any evidence of suspicious radiation.
