LONG BEACH, Calif. – Kelp off Southern California was contaminated with short-lived radioisotopes a month after Japan’s Fukushima accident, a sign that the spilled radiation reached the state’s urban coastline, according to a new scientific study.

Scientists from California State University, Long Beach tested giant kelp collected in the ocean off Orange County and other locations after the March, 2011 accident, and detected radioactive iodine, which was released from the damaged nuclear reactor.

The largest concentration was about 250-fold higher than levels found in kelp before the accident.

“Basically we saw it in all the California kelp blades we sampled,” said Steven Manley, a Cal State Long Beach biology professor who specializes in kelp.
