    Trace Amounts of Fukushima Radioactivity Detected Along Shoreline of British Columbia

    Scientists at the Woods Hole Oceanographic Institution (WHOI) have for the first time detected the presence of small amounts of radioactivity from the 2011 Fukushima Dai-ichi Nuclear Power Plant accident in a seawater sample from the shoreline of North America. The sample, which was collected on February 19 in Ucluelet, British Columbia, with the assistance of the Ucluelet Aquarium, contained trace amounts of cesium (Cs) -134 and -137, well below internationally established levels of concern to humans and marine life.

    The WHOI scientists, with the help of citizen volunteers, have collected samples at more than 60 sites along the U.S. and Canadian West Coast and Hawaii over the past 15 months for traces of radioactive isotopes from Fukushima. Last November, the team reported their first sample containing detectable radioactivity from Fukushima 100 miles (150 km) off shore of Northern California. However, no radiation had yet been found along any of the beaches or shorelines where the public has been sampling since 2013.

    “Radioactivity can be dangerous, and we should be carefully monitoring the oceans after what is certainly the largest accidental release of radioactive contaminants to the oceans in history,” said Ken Buesseler, a marine chemist at WHOI who has been measuring levels of radioactivity in seawater samples from across the Pacific since 2011. “However, the levels we detected in Ucluelet are extremely low.”

    Radiation from Japan nuclear disaster spreads off U.S. shores

    PORTLAND, Ore. (Reuters) - Radiation from Japan's 2011 nuclear disaster has spread off North American shores and contamination is increasing at previously identified sites, although levels are still too low to threaten human or ocean life, scientists said on Thursday.

    Tests of hundreds of samples of Pacific Ocean water confirmed that Japan's Fukushima nuclear power plant continues to leak radioactive isotopes more than four years after its meltdown, said Ken Buesseler, marine radiochemist with the Woods Hole Oceanographic Institution...
