California Fish Contaminated with Fukushima RadiationWashington Blog - We noted more than a year ago:
The ocean currents head from Japan to the West Coast of the U.S.
Of course, fish don’t necessarily stay still, either. For example, the Telegraph notes that scientists tagged a bluefin tuna and found that it crossed between Japan and the West Coast three times in 600 days:
And see this.
CNN reports today:
Low levels of radioactive cesium from Japan’s Fukushima Daiichi nuclear accident turned up in fish caught off California in 2011, researchers reported Monday.The Wall Street Journal quotes the studies’ authors:
The bluefin spawn off Japan, and many migrate across the Pacific Ocean. Tissue samples taken from 15 bluefin caught in August, five months after the meltdowns at Fukushima Daiichi, all contained reactor byproducts cesium-134 and cesium-137 at levels that produced radiation about 3% higher than natural background sources
“The tuna packaged it up and brought it across the world’s largest ocean,” said marine ecologist Daniel Madigan at Stanford University, who led the study team. “We were definitely surprised to see it at all and even more surprised to see it in every one we measured.” Read More
