RADIOACTIVE elements released from the tsunami-hit Japanese nuclear plant shouldn't have much effect on Shanghai, local environmental experts said yesterday, although Japanese researchers said the cesium in the Pacific Ocean is likely to flow back to Japan in 20 to 30 years after circulating in the northern Pacific in a clockwise pattern.
The finding was disclosed at a meeting of the Geochemical Society of Japan in Sapporo yesterday, according to the Kyodo news service.
The researchers estimated that the amount of radioactive cesium-137 directly released into the sea came to 3,500 terabecquerels from March to the end of May, while estimating that roughly 10,000 terabecquerels fell into the ocean after it was released into the air.
The cesium-137 leakage is triple the amount that the plant has announced previously, researchers said.
