There's good news from the tragic events following the 2011 earthquake, tsunami and 3 nuclear meltdowns in Japan. According to Cal State Long Beach marine biologist Steven Manley, Kelp Watch tests detect no radiation in West Coast Kelp forests.
“Our data does not show the presence of Fukushima radioisotopes in West Coast Giant Kelp or Bull Kelp,” Manley said in a statement. “These results should reassure the public that our coastline is safe and that we are monitoring it for these materials. At the same time, these results provide us with a baseline from which we can compare samples gathered later in the year.”
