The paper by Wetherbee, Gregory A. et al was published online on February 22, 2012 ahead of the print, on Environmental Science and Technology.
Abstract, from Environmental Science and Technology (emphasis is mine):
Using the infrastructure of the National Atmospheric Deposition Program (NADP), numerous measurements of radionuclide wet deposition over North America were made for 167 NADP sites before and after the Fukushima Dai-ichi Nuclear Power Station incident of March 12, 2011. For the period from March 8 through April 5, 2011, wet-only precipitation samples were collected by NADP and analyzed for fission-product isotopes within whole-water and filterable solid samples by the United States Geological Survey using gamma spectrometry.
