Observations of Fallout from the Fukushima Reactor Accident in San Francisco Bay Area Rainwater

We have observed fallout from the recent Fukushima Dai-ichi reactor accident in samples of rainwater collected in the San Francisco Bay area. Gamma ray spectra measured from these samples show clear evidence of fission products - 131,132I, 132Te, and 134,137Cs. The activity levels we have measured for these isotopes are very low and pose no health risk to the public.Comment: 5 pages, 2 figure
