Radiation In Calif. Kelp? Scientists To Test West Coast Water 3 Years After Fukushima Nuclear Meltdown

California biologists plan to test coastal kelp for traces of radioactive material three years after the nuclear meltdown in Fukushima, Japan. Experts are concerned that radiation, which leaked into the Pacific Ocean from Japan's Fukushima nuclear plant in March 2011, may have reached the west coast of the U.S. Scientists hope California's kelp will give them an answer.
