Japanese authorities began testing for radiation in seawater near the damaged Fukushima Daiichi nuclear plant on Tuesday, but officials stressed that the elevated levels are no cause for worry.
As engineers reported progress on stabilizing overheated reactors at the Fukushima Daiichi nuclear power plant Tuesday, elevated levels of radiation have been found in seawater nearby, fueling concern over long-term environmental and health impacts.
Plant operator Tokyo Electric Power Company (TEPCO) announced today that in samples taken 1,100 feet south of the plant on Monday, radioactive iodine exceeded legal limits for wastewater by 126.7 times, cesium-134 by 24.8 times, and cesium-137 by 16.5 times. Samples taken 16 kilometers (10 miles) south were up to 16 times above legal levels.
Radioactive elements in the ocean will not likely pose a threat to human health because they quickly become diluted, says Masaharu Hoshi, a specialist in environmental impact assessments at Hiroshima Universityâ€™s Research Institute for Radiation Biology and Medicine. He says contamination of seawater was not a problem following the atomic bombing of Hiroshima and Nagasaki.
