title: Observations of fallout from the Fukushima reactor accident in San Francisco Bay area rainwater.
abstract: 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--(131,132)I, (132)Te, and (134,137)Cs. The activity levels we have measured for these isotopes are very low and pose no health risk to the public.
