… 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 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 Wall Street Journal quotes the studies’ authors:
“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.”
“We found that absolutely every one of them had comparable concentrations of cesium-134 and cesium-137,” said marine biologist Nicholas Fisher at Stony Brook University in New York state, who was part of the study group.
The bad news is that this is only going to get worse…
