Isotopes have longer half-lives (Cs-134 has a half-life of about two years,Ĭs-137 a longer half-life of about 30 years), the radionuclides also undergoīiological excretion and do not continue to build up in fish forever. Since the event, the short-lived radionuclides would have decayed to nearīackground levels and therefore pose no health hazard. The I-131 isotope drops by half every eight days. Some radioactive isotopes rapidly decay.The massive amount of water in the Pacific Ocean would rapidly dilute andĭisperse the materials to negligible levels. Radioactive material released into the sea near the Fukushima reactor site, While there may be significant quantities of Health effect on beachgoers or seafood safety around the Hawaiian Islands, due to Water quality surveys and does not anticipate any public The Hawaii Department of Health (HDOH) continues to monitor the results of Likewise, the Hawaii State Department of Health has been monitoring Japanese water quality surveys and anticipates no public health effect in that state due to leaks from the Fukushima Daiichi nuclear plant: No matter what happens in Fukushima, it's not going to be a problem over here." "There's a lot of material between us and Japan. "The Pacific Ocean is an enormous place," said Norman, who found radiation from the Fukushima nuclear power in California rainwater, milk and plants soon after the earthquake and tsunami. Environmental Protection Agency.Įric Norman, a nuclear engineering professor at the University of California, Berkeley, said the latest leak was not a concern. "With the amount of dilution that would occur, any kind of release in Japan would be non-detectable here," said David Yogi, spokesman for the U.S. In the United States, across the Pacific, there was no sense of alarm. It had (and has) nothing to do with the flow or spread of radioactive seepage from Fukushima.Īs for whether the current Fukushima "emergency" poses a danger to residents of the U.S., American officials have stated that the diluting effects of the vast Pacific Ocean expanse would likely neutralize any deleterious effects from the radioactive seepage by the time it reached U.S. It was a plot created by the National Oceanic and Atmospheric Administration (NOAA) immediately after the Tohoku earthquake in March 2011 showing the wave height of the tsunami that followed. However, that chart did not actually track or measure radioactive discharge emanating from Fukushima in 2013, or any other aspect of the Fukushima disaster. References to these news accounts were widely circulated on the Internet accompanied by a color graphic supposedly showing the flow of radioactive discharge from Fukushima all the way across the Pacific Ocean to the western coasts of North and South America and down to Antarctica: "Right now, we have an emergency," he said. "This is why you can't just leave it up to Tepco alone" to grapple with the ongoing disaster. Tepco's "sense of crisis is weak," Kinjo said. Ĭountermeasures planned by Tokyo Electric Power Co (Tepco) are only a temporary solution, he said. ![]() This contaminated groundwater has breached an underground barrier, is rising toward the surface and is exceeding legal limits of radioactive discharge, Shinji Kinjo, head of a Nuclear Regulatory Authority (NRA) task force. Highly radioactive water seeping into the ocean from Japan's crippled Fukushima nuclear plant is creating an "emergency" that the operator is struggling to contain, an official from the country's nuclear watchdog said on Monday. In August 2013, news accounts quoted an official from Japan's Nuclear Regulatory Authority as stating that highly radioactive water was seeping from the plant into the Pacific Ocean and creating an "emergency" situation that the plant's operators were not adequately containing: The massive (8.9) Tohoku earthquake and subsequent tsunami that hit Japan in March 2011 resulted in a series of equipment failures, nuclear meltdowns and releases of radioactive materials from the Fukushima I Nuclear Power Plant, the largest nuclear disaster since the catastrophic accident at the Chernobyl Nuclear Power Plant in Ukraine in April 1986. ![]()
