Four years after the 2011 Japanese earthquake, tsunami, and a nuclear power plant meltdown, trace amounts of the radioactivity from the Fukushima nuclear power plant has been detected along the West Coast, but officials are saying it is what they predicted, and it is insignificant to human health. More than 60 sites along the Eastern Pacific Ocean and the Hawaiian Islands were set up to monitor radioactivity from Japan, but so far the amounts detected have been well below a level of concern for humans and marine species. Scientists at Oregon State University also participated in the research and agreed the amount of radioactivity leaked across the Pacific was insignificant or undetectable.
