A new study published lately in the Proceedings of the Nation Academy of Sciences has uncovered that the radioactive nuclides released from the Fukushima nuclear power plants have entered Pacific bluefin tuna, thereby polluting them.
The team of researchers at Stanford University in California has revealed that 15 tuna that had been caught off Southern California have been found to have consumed the polluting components.
While the amount of pollutants consumed is ten times higher than that found generally in tuna in that area, it is being said that the fish are safe to be consumed. It has been told that the levels of cesium i. e. cesium 134 and cesium 137, taken in by them was still only one-tenth of the level hazardous to humans.
The study has found that the huge Fukushima explosion is the outcome of earthquake that occurred on March 11, 2011 and tsunami in Japan. It is being said that the fish that produce in the Sea of Japan need some months to reduce the levels of radioactivity.
"If concentrations in water will eventually decline, as we would expect, due to dilution and dispersion, then concentrations in living organisms will eventually decline as well", says Fisher, a professor at Stony Brook University in New York.
