Ionising radiation moves up in the marine food chain
Radiation and Mercury in Fish: Should Americans be Concerned? One Green Planet June 5, 2012 by Joseph Keon: The May 29th issue of the Proceedings of the National Academy of Sciences reported that fish caught off the California coast in 2011 by researchers from Stony Brook University in New York were contaminated with radioactive waste from the crippled Fukushima nuclear power facility.
The radioactive isotopes cesium-137 and cesium-134 were found in blue fin tuna at levels ten times higher than in the years prior to the accident, roughly four months after the waste was released into the ocean. Seven months after the accident, Japan’s Fisheries Agency reported broad-spread radioactive contamination (up to 100 percent) in fish caught both in Japanese coastal waters and hundreds of miles away.
Problems with Radioactive Waste Predate Fukushima Even before Fukushima, fish have been shown to carry radioactive waste from the nuclear industry. Tests of salmon from six British supermarkets revealed contamination by the radioactive isotope technetium-99, which has also been found in lobster and shellfish, and has been traced to Britain’s Sellafield nuclear reprocessing plant, even though the fish were raised hundreds of miles away.
According to James Waczewski of Florida State University, author of Legal, Political, and Scientific Response to Ocean Dumping, the United States has dumped an estimated 112,000 containers of long-lived radioactive nuclear waste into the Pacific and Atlantic oceans at 30 different sites. A U.S. Senate ruling has since imposed a moratorium on this practice, but nuclear power plants continue to discharge radioactive waste-water into the world’s oceans daily.
No Fish from the Ocean Is Protected Because ionizing radiation from nuclear waste is a carcinogen,
radioactivity in fish is a disturbing reality. Yet even without the Fukushima disaster, the world’s fish supply has become a dubious source of nutrition…….
Although we seldom see the waste floating on the surface of the oceans, if we’re willing to test it, we find that sea life has become our proverbial “canary in the coal mine,” clearly revealing the hidden truth of all that has infiltrated the world’s oceans. Some bodies of water are vastly more polluted than others, but one toxin, mercury, permeates the world’s oceans to such a degree that no fish (and no one who eats fish) is protected.
Mercury in Fish Mercury is a toxic substance that can devastate the nervous system,
leading to lower intelligence and compromised fine motor skills. …..
