There is always concern when something radioactive is released as to what its downwind effects might be. Certainly there are effects at the actual site but thousands of miles away? Fallout from the 2011 Fukushima Dai-ichi nuclear power facility in Japan was measured in minimal amounts in precipitation in the United States in about 20 percent of 167 sites sampled in a nationwide study released today. The U.S. Geological Survey led the study as part of the National Atmospheric Deposition Program (NADP). Levels measured were similar to measurements made by the U.S. Environmental Protection Agency in the immediate days and weeks following the March 2011 incident, which were determined to be well below any level of public health concern at the time by EPA.
