An unstoppable tide of radioactive trash and chemical waste from Fukushima is pushing ever closer to North America. An estimated 20 million tons of smashed timber, capsized boats and industrial wreckage is more than halfway across the ocean, based on sightings off Midway by a Russian ship's crew. Safe disposal of the solid waste will be monumental task, but the greater threat lies in the invisible chemical stew mixed with sea water.

This new triple disaster floating from northeast Japan is an unprecedented nuclear, biological and chemical (NBC) contamination event. Radioactive isotopes cesium and strontium are by now in the marine food chain, moving up the bio-ladder from plankton to invertebrates like squid and then into fish like salmon and halibut. Sea animals are also exposed to the millions of tons of biological waste from pig farms and untreated sludge from tsunami-engulfed coast of Japan, transporting pathogens including the avian influenza virus, which is known to infect fish and turtles. The chemical contamination, either liquid or leached out of plastic and painted metal, will likely have the most immediate effects of harming human health and exterminating marine animals.

Many chemical compounds are volatile and can evaporate with water to form clouds, which will eventually precipitate as rainfall across Canada and the northern United States. The long-term threat extends far inland to the Rockies and beyond, affecting agriculture, rivers, reservoirs and, eventually, aquifers and well water.   Falsifying Oceanography

The United States secretly sought Japan's support in 1972 to enable it to dump decommissioned nuclear reactors into the world's oceans under the London Convention, an international treaty being drawn up at the time. Countries working on the wording of the pact wanted to specifically prohibit the dumping of radioactive waste at sea.

But Washington wanted to incorporate an exceptional clause in the case of decommissioned nuclear reactors. These facts came to light in diplomatic records held by the Foreign Ministry in Tokyo and released at the request of The Asahi Shimbun.

The documents obtained by The Asahi Shimbun were signed by Japan's ambassador to Britain and designated as top secret. According to the records, a U.S. State Department official who was part of the U.S. delegation discussing the terms of the treaty, met his Japanese counterpart in November 1972. In that meeting, the official explained that the United States had a number of early-stage nuclear reactors which had reached their life spans. He said Washington was facing problems disposing of them.

Six months after the accident at Fukushima Daiichi, the news flow from the stricken nuclear power plant has slowed, but scientific studies of radioactive material in the ocean are just beginning to bear fruit.The word from the land is bad enough. As my colleague Hiroko Tabuchi reported on Saturday, Japanese officials have detected elevated radiation levels in rice near the crippled reactors. Worrying radiation levels had already been detected in beef, milk, spinach and tea leaves, leading to recalls and bans on shipments.

Off the coast, the early results indicate that very large amounts of radioactive materials were released, and may still be leaking, and that rather than being spread through the whole ocean, currents are keeping a lot of the material concentrated. Most of that contamination came from attempts to cool the reactors and spent fuel pools, which flushed material from the plant into the ocean, and from direct leaks from the damaged facilities.

Japanese government and utility industry scientists estimated this month that 3,500 terabecquerels of cesium 137 was released directly into the sea from March 11, the date of the earthquake and tsunami, to late May. Another 10,000 terabecquerels of cesium 137 made it into the ocean after escaping from the plant as steam.

Nuclear power plants in Pennsylvania are preparing to cope with flooding, but none has declared a state of emergency, US Nuclear Regulatory Commission spokesman Neil Sheehan said Thursday. All the Pennsylvania nuclear plants that could potentially be affected by flooding are in close communication with NRC, and with state and local officials, and the agency has resident inspectors at each plant who are monitoring the situation, Sheehan said. The plants were all operating at full power early Thursday, according to NRC data, except for Exelon Nuclear's Peach Bottom-3, which was at 88% power and has been gradually reducing its output for several days ahead of refueling outage.

Emergency diesel generators and their fuel tanks at those plants are "located at a higher elevation, in buildings designed to keep them dry," Sheehan said. Exelon Nuclear's Three Mile Island-1, located along the Susquehanna River, 10 miles southeast of Harrisburg, began its abnormal operating procedure for river flooding early Wednesday, Sheehan said. The river peaked at 291 feet above sea level Wednesday and was at 288 feet above sea level early Thursday. It is expected to crest Thursday at about 297 feet above sea level, he said.

If the river reaches 300 feet above sea level, then the plant would have to declare an unusual event, the least significant of NRC's four emergency levels, Sheehan said. If the river reaches 302 feet above sea level, the plant would need to shut and an alert, the next highest level of emergency, would need to be declared. "Important equipment" at Three Mile Island-1 is protected against flooding up to about 315 feet above sea level, Sheehan said.

Following up this article http://fukushima-diary.com/2011/12/220t-of-highly-radioactive-water-leaked-and-a-part-of-it-leaked-to-the-sea/ The water purifying system has never worked properly. It was urgently constructed , the whole system can’t stand anymore. These are the tweets of actual Fukushima worker ,Happy20790. He explains how it is on the sight.

<Translation> The contaminated water leaks a lot recently. This time ,it went out of the “building” so it was reported but actually it happens frequently. I called it “a building” ,but it’s actually a temporary tent on a temporary concrete basement. It leaked from the first operation ,so they made a tiny dam in it. Maybe it’s only 20cm high. I don’t get into the tent recently because it’s too radioactive,but I used to pump up leaked contaminated water. The contaminated water emits a lot of beta ray ,so you need to be careful. This time ,Tepco’s spokes man said it was 110mSv/h ,but it is higher at some points. The concrete basement was constructed really urgently. They built the tent even before the concrete dried. so it got cracked already. Other tent may have the same problems too. Unlike our ordinary contract ,makers only set the facility ,they don’t take responsibility of handing or maintenance. As I tweeted before,this water purifying system is not a long-lasting system. It is a temporary system without proper planning process. In order to release cooling water to the sea ,we must install more proper facility. Now the gutter is straightly connected to the sea. They must be shut down or a dam must be made. Currently every time it rains, radiation on the ground and radiation stuck to the plants flow into the sea straightly. Makers and workers are already withdrawing from Fukushima plants ,but Tepco has no long term plan. They need to predict the future risk and prevent it from happening in advance.

While the 2011 earthquake and worries surrounding Fukushima have brought the threat of radioactivity back into the public consciousness, many people still don't realize that radioactive contamination is a worldwide danger. Radionuclides are in the top six toxic threats as listed in the 2010 report by The Blacksmith Institute, an NGO dedicated to tackling pollution. You might be surprised by the locations of some of the world’s most radioactive places — and thus the number of people living in fear of the effects radiation could have on them and their children.

10. Hanford, USA

The Hanford Site, in Washington, was an integral part of the US atomic bomb project, manufacturing plutonium for the first nuclear bomb and "Fat Man," used at Nagasaki. As the Cold War waged on, it ramped up production, supplying plutonium for most of America's 60,000 nuclear weapons. Although decommissioned, it still holds two thirds of the volume of the country’s high-level radioactive waste — about 53 million gallons of liquid waste, 25 million cubic feet of solid waste and 200 square miles of contaminated groundwater underneath the area, making it the most contaminated site in the US. The environmental devastation of this area makes it clear that the threat of radioactivity is not simply something that will arrive in a missile attack, but could be lurking in the heart of your own country.

No more gas masks, because it does not work anymore. Tepco secretly measured tritium from sea water on 9/12 and announced it on 10/15. 2,400 Bq/L at sub-drain of reactor 2. (Plus, all kinds of beta nuclides were measured.) 470 Bq/L at intake of reactor 1~4.(Plus, all kinds of beta nuclides were measured.) (Source)(Source) They have not announced why they took one month to publish the data. Tritium is radioactive hydrogen.

It is in the form of H20. Once it comes out of the reactor, it comes up and fall down in the air as rain, and it goes back to the sea again. It repeats the cycle. Half life time is 12 years. It is the main material of hydrogen bomb. In normal times, it’s less than 1 Bq/L in the sea. It easily comes into tap water, and your own cells as water and cause severe internal exposure. It’s impossible to filter it out. Dr.C Busby explains: If you put sea water into the reactor, the reactor becomes a tritium producing machine.

Note,the PDF file of the data was locked to upload by Tepco,so I had to upload the screen shot instead.I have no idea why.

No one wants to think about the massive aqueous deposition of radioactive materials into the Pacific Ocean, that much is now clear. By September estimates of released contamination had risen to over  3,500 terabecquerels of cesium-137 released into the sea directly from the plant between March 11 and the end of May. Another 10,000 terabecquerels of cesium fell into the ocean after escaping from the reactors in the form of steam.

"The question is, what is a reasonable interval to give people information?" said Dr. Robert Peter Gale, an American physician and expert on radiation who consulted on the 1986 nuclear disaster in Chernobyl and is now advising Japan's government. "Instead of just releasing each data point you get, sometimes it's better to base things on an average of readings over a period of time." Source: LA Times

Experts Don't Fear A Radiation Graveyard Water was constantly required for the workers to be able to get any cooling into Reactors 1-4, when water went in, steam came out.  The ocean quickly became the radiation dumping ground, as untold tonnes of contaminated water has been confirmed to have directly flowed into the ocean, and TEPCO continually assured Japanese citizens that the majority of dispersal would occur over the Pacific.

The impacts on the ocean of releases of radionuclides from the Fukushima Dai-ichi nuclear power plants remain unclear. However, information has been made public regarding the concentrations of radioactive isotopes of iodine and cesium in ocean water near the discharge point. These data allow us to draw some basic conclusions about the relative levels of radionuclides released which can be compared to prior ocean studies and be used to address dose consequences as discussed by Garnier-Laplace et al. in this journal.(1) The data show peak ocean discharges in early April, one month after the earthquake and a factor of 1000 decrease in the month following. Interestingly, the concentrations through the end of July remain higher than expected implying continued releases from the reactors or other contaminated sources, such as groundwater or coastal sediments. By July, levels of 137Cs are still more than 10 000 times higher than levels measured in 2010 in the coastal waters off Japan. Although some radionuclides are significantly elevated, dose calculations suggest minimal impact on marine biota or humans due to direct exposure in surrounding ocean waters, though considerations for biological uptake and consumption of seafood are discussed and further study is warranted.

there was no large explosive release of core reactor material, so most of the isotopes reported to have spread thus far via atmospheric fallout are primarily the radioactive gases plus fission products such as cesium, which are volatilized at the high temperatures in the reactor core, or during explosions and fires. However, some nonvolatile activation products and fuel rod materials may have been released when the corrosive brines and acidic waters used to cool the reactors interacted with the ruptured fuel rods, carrying radioactive materials into the ground and ocean. The full magnitude of the release has not been well documented, nor is there data on many of the possible isotopes released, but we do have significant information on the concentration of several isotopes of Cs and I in the ocean near the release point which have been publically available since shortly after the accident started.

We present a comparison of selected data made publicly available from a Japanese company and agencies and compare these to prior published radionuclide concentrations in the oceans. The primary sources included TEPCO (Tokyo Electric Power Company), which reported data in regular press releases(3) and are compiled here (Supporting Information Table S1). These TEPCO data were obtained by initially sampling 500 mL surface ocean water from shore and direct counting on high-purity germanium gamma detectors for 15 min at laboratories at the Fukushima Dai-ni NPPs. They reported initially results for 131I (t1/2 = 8.02 days), 134Cs (t1/2 = 2.065 years) and 137Cs (t1/2 = 30.07 years). Data from MEXT (Ministry of Education, Culture, Sports, Science and Technology—Japan) were also released on a public Web site(4) and are based on similar direct counting methods. In general MEXT data were obtained by sampling 2000 mL seawater and direct counting on high-purity germanium gamma detectors for 1 h in a 2 L Marinelli beaker at laboratories in the Japan Atomic Energy Agency. The detection limit of 137Cs measurements are about 20 000 Bq m–3 for TEPCO data and 10 000 Bq m–3 for MEXT data, respectively. These measurements were conducted based on a guideline described by MEXT.(5) Both sources are considered reliable given the common activity ratios and prior studies and expertise evident by several Japanese groups involved in making these measurements. The purpose of these early monitoring activities was out of concern for immediate health effects, and thus were often reported relative to statutory limits adopted by Japanese authorities, and thus not in concentration units (reported as scaling factors above “normal”). Here we convert values from both sources to radionuclide activity units common to prior ocean studies of fallout in the ocean (Bq m–3) for ease of comparison to previously published data.

Mr.Mizobuchi Yukio ,the chairman of sea turtle association of Japan,found out 50 of 87 green turtle’s eggs were deformed. Normal eggs are 4 cm diameter ,but deformed ones are 6 cm diameter and various width. The smallest egg was only 1.5 cm diameter. They were deposited early in the morning of 6/5/2011,in Hirano surf beach ,Shimanto shi Kochi.On 6/4 ,the turtle came to a different beach called Futami kaigan,where it was born.However,it went back to the sea without leaving eggs and deposited eggs in Hirano surf beach ,where it wasn’t born. This is unusual case for sea turtles. Last year,sea turtles deposited eggs from 5/17~8/4 in Hirano surf beach. It was 5/22~8/4 in Futami kaigan. However,this year ,they deposited eggs on 6/5 for the first time in Hirano surf beach. In Futami kaigan ,they deposited eggs in 5/12 but didn’t come back until 6/3.

Japan Agency for Marine-Earth Science and Technology announced that in April, Cesium from Fukushima dropped from air to the pacific ocean and fell down deep in the sea attached to dead plankton. 4/18~4/30, Japan Agency for Marine-Earth Science and Technology measured cesium from particles which is made of dead plankton or sand, smaller than 1mm, called “Marine snow”. It was off shore of Polustrov Kamchatka, where is 2,000 km away from Fukushima and 5,000 meters deep in the sea around Ogasawara islands, where is 1,000 km away from Fukushima. From the ratio of cesium 134 and 137, they judged it was from Fukushima plants. They have not announced the amount of cesium. (Source)

An unknown disease is killing or weakening scores of ringed seals along Alaska’s north coast, where the animals have been found with lesions on their hind flippers and inside their mouths. Ringed seals, the main prey of polar bears, and a species that rarely comes ashore, in late July began showing up on the Beaufort Sea coast outside Barrow with the lesions, patchy hair loss and skin irritation around the nose and eyes. The outbreak was reported first in the Alaska Dispatch.

Officials from the National Marine Fisheries Service and the North Slope Borough said Thursday that 107 animals were found stranded from late July through Sept. 29 and 99 appeared to have lesions. Nearly half died. “Forty-six of the animals were dead when found, or died shortly thereafter,” said Julie Speegle, spokeswoman for the National Marine Fisheries Service. Seals still alive were lethargic or showing labored breathing.Necropsies revealed lesions were not limited to skin of seals. Biologists studying the dead animals found lesions in the respiratory system, liver, lymphoid system, heart and brain, she said.

Wildlife authorities in Canada and Russia have reported similar incidents, she said. “We don’t know if they’re related, but they’re similar,” Speegle said.Linda Deger, a spokeswoman for Fisheries and Oceans Canada, said by email that ringed seals are the only species reported to be affected and the department and other agencies are investigating. “At this point, we don’t know exactly what is causing it,” Speegle said. “Laboratory findings have been inconclusive to date but samples have tested negative for pox virus, herpes virus, papillomavirus, morbillivirus and calicivirus.”

Enormous quantities of decommissioned Russian nuclear reactors and radioactive waste were dumped into the Kara Sea in the Arctic Ocean north of Siberia over a course of decades, according to documents given to Norwegian officials by Russian authorities and published in Norwegian media.

Bellona is alarmed by the extent of the dumped Soviet waste, which is far greater than was previously known – not only to Bellona, but also to the Russian authorities themselves.

The catalogue of waste dumped at sea by the Soviets, according to documents seen by Bellona, and which were today released by the Norwegian daily Aftenposten, includes some 17,000 containers of radioactive waste, 19 ships containing radioactive waste, 14 nuclear reactors, including five that still contain spent nuclear fuel; 735 other pieces of radiactively contaminated heavy machinery, and the K-27 nuclear submarine with its two reactors loaded with nuclear fuel.

Japanese Tsunami Flotsam Appearing In Kodiak Waters, KMXT by Jennifer Canfield, December 26, 2011:

Dr. Curtis Ebbesmeyer [...] says debris will continue to wash up on shores from Kodiak to Oregon for the next few years [...] Ebbesmeyer says scientists are already hypothesizing about the effects of mass amounts of debris traveling through the Pacific Ocean’s currents. He points to an unprecedented number of sea turtles washing up on Vancouver Island. Ebbesmeyer says people who find debris should be especially careful and respectful. Personal items and artifacts can still be reunited with people in Japan. He also suggests testing items for radiation, just to be prudent.  [...]
