– Top Headline: ‘Fukushima radiation identified off northern California’ — 50% of samples around West Coast test positive — 7.7 Bq/m3 of cesium near California shore, expected to keep rising for years to come (MAP) (ENENews, Nov 11, 2014):
Statesman Journal, Nov. 10, 2014 at 8:22a ET: Fukushima radiation identified off northern California — Low-level radiation from Japan’s Fukushima nuclear accident has been detected in multiple samples of ocean water off the Pacific Coast of the U.S. and Canada, the Woods Hole Oceanographic Institution is reporting. The sample nearest to shore was taken about 100 miles off the coast of Eureka, in Northern California… Massive amounts of contaminated water were released from the Fukushima Dai-ichi nuclear power plant… Radioactive water has continued to leak and be released from the complex… No state or federal agency is testing Pacific waters for radiation… [Ken Buesseler, a WHOI marine chemist] is looking for cesium-134, the so-called “fingerprint” of Fukushima… He’s also looking for higher-than-background levels of cesium-137, another Fukushima isotope that already is present in the world’s oceans… Buesseler partnered with a group of volunteers on the research vessel ‘Point Sur’ to take a series of about 50 samples offshore, from Dutch Harbor, Alaska to Eureka. So far, about 20 of those samples have been analyzed, and 10 have been positive for cesium-134…
Ken Buesseler, WHOI: “The models predict cesium levels to increase over the next two to three years, but do a poor job describing how much more dilution will take place and where those waters will reach the shoreline first.”
Ken Buesseler, Reddit’s ‘Ask Me Anything‘, Nov. 10, 2014 at 8:30a ET: I’m Ken Buesseler, an oceanographer who studies marine radioactivity. I’ve been doing this since I was a graduate student, looking at plutonium in the Atlantic deposited from the atmospheric nuclear weapons testing that peaked in the early 1960’s. Then came Chernobyl in 1986, the year of my PhD… The triple disaster of the 2011 “Tohoku” earthquake, tsunami, and subsequent radiation releases at Fukushima Dai-ichi were unprecedented events for the ocean and society… the cooling waters and contaminated groundwater enter the ocean directly, and still can be measured to this day. Across the Pacific, ocean currents carrying Fukushima cesium are predicted to be detectable along the west coast of North America by 2014 or 2015, and though models suggest at levels below those considered of human health concern, measurements are needed. That being said, in the US, no federal agency has taken on this task… new sampling efforts further offshore have confirmed the presence of small amounts of radioactivity from the 2011 Fukushima Dai-ichi Nuclear Power Plant 100 miles (150 km) due west of Eureka. What does that mean for our oceans?
