TV: Fukushima radioactive releases into ocean can continue thousands of more years, says nuclear expert — Japan gov’t concerned with tracking radioactive waste in Pacific as it returns to Fukushima from U.S. West Coast after several decades (VIDEO) http://enenews.com/tv-radioactive-releases-pacific-thousands-years-fukushima-melted-fuel-be-removed-nuclear-expert-japan-govt-concerned-radioactive-waste-ocean-coming-fukushima-several-decades-after-being-west-coast?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+ENENews+%28Energy+News%29
American Chemical Society — Environmental Science & Technology (pdf),Apr. 29, 2014 (emphasis added): 135Cs/137Cs Isotopic Ratio as a New Tracer of Radiocesium Released from the Fukushima Nuclear Accident [...] many important issues with respect to its atmospheric transport, deposition processes, and distributions in terrestrial and marine environments remain to be investigated. It has been estimated that ∼80% of the atmospherically released 137Cs was deposited in the western North Pacific Ocean, in addition to [...] 137Cs directly discharged into the ocean [...] continuous input of 137Cs into the ocean due to river runoff of the 137Cs deposited in heavily contaminated Fukushima forest soil can be expected. Recent studies have revealed the start of the transport of the Fukushima accident-sourced 137Cs into the ocean interior [...] it is predicted that in 30 years the Fukushima accident-derived 137Cs will come back to the ocean surface in the western North Pacific Ocean off the Fukushima coast through its transport by the Kuroshio current. Thus, to understand the environmental behavior and the fate of Fukushima accident-sourced radionuclides in the environment, a powerful Cs tracer is strongly required, because the currently widely used 134Cs/137Cs activity ratio tracer will become unavailable in several years because of the rapid decay of 134Cs [...] 135Cs has a half-life of 2 × 10^6 [2.3 million] years; therefore, we are confident that the 135Cs/137Cs isotopic ratio can be considered as a new powerful tracer for long-term source identification and environmental behavior studies. [...] This study was supported [...] partially by the Agency for Natural Resources and Energy, the Ministry of Economy, Trade and Industry (METI), Japan [7 of study's 8 authors are from Japan's National Institute of Radiological Sciences]
Nuclear analyst John Large, July 9, 2014: The cores remain active for hundreds, if not thousands, of years, so there’s a commitment to keep either the ice wall technology in place or to replace it with an alternate technology by some future generation. […] Water is coming off the escarpment above the three reactors, it’s then percolating through the ground — there’s hydrostatic pressures pushing the water up toward the sea level — it’s then collecting the fission products and radioactive products from the melted-down cores and taken out to sea. […] What I think they should now have a plan to tackle the root cause… How do you control, manage and eventually remove the reactor cores? […] If the reactor cores remain in there, it’s going to be a constant leachate (water that percolates through a solid and leaches out some of the constituents) of radioactivity.
Japan Gov’t-funded Study: Fukushima has released up to 120 Quadrillion becquerels of radioactive cesium into North Pacific Ocean — Does not include amounts that fell on land — Exceeds Chernobyl total, which accounts for releases deposited on land AND ocean (MAP) http://enenews.com/japan-govt-funded-study-fukushima-released-120-quadrillion-becquerels-radioactive-cesium-north-pacific-ocean-include-amount-deposited-land-higher-total-amount-released-chernobyl?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+ENENews+%28Energy+News%29 1 July 14,
Scientific Reports (Nature.com), Mar. 4 2014: The total amount of decay-corrected 134Cs in the [subtropical] mode water was an estimated about 6 PBq [petabecquerels, i.e. 6 quadrillion becquerels] corresponding to 10–60% of the total inventory of Fukushima-derived 134Cs in the North Pacific Ocean. […] The decay corrected ratio of 134Cs/137Cs in soils has been calculated to be 1.0, which suggests that the total amounts of 134Cs and 137Cs released from FNPP1 were equivalent. […] the total amount of Fukushima-derived radiocesium in the North Pacific remains uncertain, because it has been difficult to obtain sufficient samples of water, especially from subsurface and deep waters, in the vast North Pacific Ocean […] Estimates of the total 134Cs released to the North Pacific Ocean ranged from 10 PBq (direct discharge of 4 PBq + atmospheric deposition 6 PBq) to 46 PBq (16 + 30 PBq). Thus, the 6 PBq inventory accounts for 10–60% of the total release. However, the total inventory in the subtropical region derived from the activity in STMW [Subtropical Mode Water] may be underestimated, because CMW probably carried the radiocesium into the subtropical region, too […] The estimated inventory in the subtropical region (6 PBq or 10– 60% of the total inventory) is probably a lower limit of estimation because contribution of CMW [Central Mode Water] was not counted. [...]
Funding: “This work was partially supported by a Grant-in-Aid… from the Ministry of Education, Culture, Sports, Science and Technology of Japan”
Note: The study states that up to 46 PBq of 134Cs is estimated to have been released into the North Pacific Ocean from Fukushima Daiichi. Yet, it also states that the 6 PBq in the study area represents between 10-60% of the total 134Cs released into the North Pacific Ocean. If the 10% figure is used, the total release into the N. Pacific would equal 60 PBq of 134Cs. The study also states the releases of 134Cs and 137Cs were equivalent, resulting in a total of 120 PBq into the N. Pacific. This total does not include releases deposited on land or in other bodies of water.
Chernobyl Comparison: A report by the Nuclear Enrgy Agency states that when more detailed deposition data eventually became available, the United Nations estimated the total Chernobyl release of 137Cs at 70 PBq. 134Cs is estimated to have been 53.7% of the 137Cs — approximately 38 PBq of 134Cs — resulting in a total of 108 PBq. Unlike the Fukushima total reported above, this does include all 134Cs and 137Cs releases from Chernobyl — not just what was deposited in the ocean.
And: Marine Chemist in Jan. 2014: Latest numbers I have are Fukushima has released 80 Quadrillion Bq of cesium-137 (Chernobyl estimated at 70 Quadrillion) — “The radioactive plume itself has actually arrived… it’s already here” on west coast of N. America (AUDIO)
Fukushima radiation concerns coastal communities Tracy Loew, Statesman Journal 25 June 14, Talk in the Oregon coast town of Bandon often turns to the approaching plume of sea-borne radiation from Japan’s crippled Fukushima nuclear power plant.
“We’ve been worried about it and worried about it,” said Zac Adams, owner of Bandon Designsconstruction company. “We’re really concerned about it affecting the fisheries, the wildlife, the tourism, and most importantly our health.”…….
The radiation is expected to hit the U.S. this year at very low levels that wouldn’t harm humans or the environment. But no federal agency is monitoring it.
So Adams joined a citizen-science project, crowd-sourcing funds in his community to test a sample of seawater that he will soon collect.
Four hours north, the Tillamook Estuaries Partnership has funded two collection sites, in Tillamook and Pacific City.
“Over the last year-and-a-half, it’s been an issue that’s been raising in prominence along the coastline,” said Lisa Phipps, executive director of the partnership. “In our area, there have been groups that have been coming together to talk about what is happening in the ocean.”
And fund-raising is underway for two more sites, in Newport and Winchester Bay.
Altogether about 30 sites, from Alaska to Baja, Calif., have been funded, said Ken Buesseler, a chemical oceanographer at the Woods Hole Oceanographic Institution who put together the project, called “How Radioactive is Our Ocean?”
It uses crowd-sourced money and volunteers to collect water samples along the Pacific Coast, then ship them to Buesseler in Massachusetts to be analyzed on an $80,000 instrument………
Buesseler is looking for increased levels of Cesium-137, which already is in all oceans from previous nuclear testing and accidents; and for Cesium-134, a “fingerprint” of Fukushima.
Because of its short, two-year half-life, any Cesium-134 could only have come from the plant, he said.
So far, Buesseler said, no samples have indicated that the plume has reached the West Coast.
“We know it’s out there,” Buesseler said. “We’ve seen it more than halfway across the Pacific.”
Northwest of Hawaii, for example, Buesseler has found Cesium-134 at concentrations as high as 3.8 becquerels per cubic meter.
But to put that in context, he said, the U.S. drinking water limit is 7,400 of those units.
“Every additional radiation exposure causes additional risks for cancer,” he said. “But when the numbers are in the one to 10 range, that’s a very small additional risk.”
That’s the range that is expected to hit our shores, with lower levels coming first.
“As the contamination arrives, we expect the concentrations to go up over the next two years,” Buesseler said……..http://www.statesmanjournal.com/story/tech/science/environment/2014/06/25/fukushima-radiation-concerns-coastal-communities/11377463/
Record high radiation in seawater off Fukushima plant, Japan Times, 17 May 14 Radiation has spiked to all-time highs at five monitoring points in waters adjacent to the crippled Fukushima No. 1 power station, plant operator Tokyo Electric Power Co. said Friday.
The measurements follow similar highs detected in groundwater at the plant. Officials of Tepco, as the utility is known, said the cause of the seawater spike is unknown.
Three of the monitoring sites are inside the wrecked plant’s adjacent port, which ships once used to supply it.
At one sampling point in the port, between the water intakes for the No. 2 and No. 3 reactors, 1,900 becquerels per liter of tritium was detected Monday, up from a previous high of 1,400 becquerels measured on April 14, Tepco said.
Nearby, also within the port, tritium levels were found to have spiked to 1,400 becquerels, from a previous high of 1,200 becquerels.
And at a point between the water intakes for the No. 1 and No. 2 reactors, seawater sampled Thursday was found to contain 840 becquerels of strontium-90, which causes bone cancer, and other beta ray-emitting isotopes, up from a previous record of 540 becquerels.
At two monitoring sites outside the port, seawater was found Monday to contain 8.7 becquerels and 4.3 becquerels of tritium. The second site was about 3 km away……… http://www.japantimes.co.jp/news/2014/05/17/national/record-high-radiation-in-seawater-off-fukushima-plant/#.U3ptgdJdWik
Japan’s TEPCO to Start Dumping Fukushima Water into Ocean Next Week MOSCOW, May 16 (RIA Novosti) – Tokyo Electric Power (TEPCO), the operator of the crippled Fukushima nuclear power plant, plans to begin releasing underground water near the facility into the Pacific Ocean as early as next Wednesday, The Asahi Shimbun reported Friday.
The first water to be released will total around 560 tons, the agency said citing an official from the Ministry of Economy, Trade and Industry. TEPCO will begin releasing the water as soon as it presents results of radiation tests to local government and the fishing industry.
Initial talks between the government and TEPCO agreed that only water with 1,500 becquerels of radiation or less per liter could be released. Tests conducted by TEPCO and two outside agencies have revealed that the Fukushima underground water met the standards, averaging 220 to 240 becquerels of tritium per liter.
TEPCO began pumping out groundwater from the Fukushima nuclear plant in April in an effort to prevent further radioactive leaks.
The company continues to grapple with the problem of contaminated water storage, with about 450,000 tons of highly-radioactive water currently being stored in Fukushima’s underground facilities and tanks. Experts say some 15,000 tons is also being held in a service tunnel. According to recent estimates, up to 400 tons of contaminated water from the damaged plant is seeping into the Pacific Ocean every day.
In an effort to prevent further irradiation, TEPCO has adopted a plan to draw off groundwater from the plant. The fallout from Fukushima is later to be sent for analysis that will determine whether it is safe to be disposed of by dumping into the ocean.
The practice will allow the operator to reduce the accumulation of radioactive water at the plant by 100 tons a day……..https://news.google.com/news?ncl=d_uao6qIU8QsFkM74lsq0LkpKVl4M&q=radiation&lr=English&hl=en&sa=X&ei=l7N2U52sB8mtlQXZ_4HYBw&sqi=2&pjf=1&ved=0CDsQqgIwAw
You Know the Ocean’s in Trouble When Your Shell Starts Melting http://www.enn.com/wildlife/article/47393 Things are getting really dicey for a little ocean creature called a pteropod. Better known as the “sea butterfly,” this delicate little sea snail is serving as an unfortunate bellwether of the deteriorating state of our oceans. Why? Conditions in the Antarctic ocean and along the West Coast of the U.S. have become so unnaturally acidic that the shells of sea butterflies are literally dissolving away.
“We did not expect to see pteropods being affected to this extent in our coastal region for several decades,” said Dr. William Peterson, an oceanographer at National Oceanic and Atmospheric Administration (NOAA)’s Northwest Fisheries Science Center, in a NOAA press release.
Damage that’s “several decades” early is a big alarm bell. We’d better pay close attention before it’s too late.
The chemistry of the world’s oceans is changing, thanks to the carbon dioxide humans continue to spew into our atmosphere. Oceans absorb between one quarter to one third of that carbon dioxide. Over time, it has turned the ocean from a slightly alkaline state to a bit more acidic.
According to some estimates, the ocean’s pH level 150 years ago was about 8.2. It’s now about 8.1. It may seem to be an infinitesimal shift, but it’s worse than it sounds. The more acidic the ocean gets, the harder it is for marine life like oysters, clams and corals to form calcium carbonite skeletons and shells.
In the case of pteropods, the increased acidity of the ocean is actually eating away at their shells.
“The first thing that happens is the dissolution of their shell,” NOAA’s Dr. Nina Bednarsek told PBS. “Dissolution can be mild, [to] very severe. Once you have it dissolving on the outside, you have to put so much more energy into the shell in order to maintain it. The energy that you would otherwise use for other important physiological maintenance you are putting in the shell maintenance.”
Researchers working off the coast of Oregon, Washington and California in 2011 discovered that over half of the sea butterflies they found onshore were victims of “severe dissolution damage.” Offshore, about 24 percent were damaged.
If we don’t change our ways, by 2050, researchers estimate that coastal waters will be 70 percent more acidic than they were in the pre-industrial era.

This Huge Nuclear Waste Dump Will Be Washed Away By Rising Sea Levels http://gizmodo.com/uk-nuclear-waste-dump-will-be-washed-away-by-rising-sea-1565513267 21 April 14, Geoff Manaugh A dumping ground for nuclear waste located near the British coast is “virtually certain” to be washed away by rising sea levels, a new report warns. The UK Environment Agency has admitted that constructing the Drigg Low-Level Waste Repository so near the coast was a mistake, and that one million cubic meters of nuclear waste will begin leaking into the ocean “a few hundred to a few thousand years from now.”
Sounds bad? Pay no attention, then, to current plans to increase the site’s capacity by another 800,000 cubic meters over the next century, adding new waste that will include “radioactive debris from Britain’s nuclear power stations, nuclear submarines, nuclear weapons, hospitals and universities,” the Guardian reports.
It’s interesting to note that, while the site officially contains only low-level waste, there is suspicion that higher-level wastes with correspondingly higher levels of radioactivity could have been dumped there in the past. Recall the incredible tale of Sellafield nuclear power station—the site from which much of the waste now stored at Drigg originates—where records of previous dumping had been thrown away or lost. This led to the terrifying need to advertise in the local newspaper, saying: “We need your help.” Why? Because they had no idea what was buried there.
“Did you work at Sellafield in the 1960s, 1970s or 1980s?” the ad asked with false calm. “Were you by chance in the job of disposing of radioactive material? If so, the owners of Britain’s nuclear waste dump would very much like to hear from you: they want you to tell them what you dumped—and where you put it.”
In any case, the coastal tomb at Drigg is all but guaranteed to break apart in the waves and wash its mysterious and harmful contents into the sea. “A few hundred to a few thousand years from now” sounds like a long time, of course, but think of that as potentially little more than the time between us and Shakespeare (400 years), and the terrifying urgency of this becomes more clear.

Russia, Norway urge raising of dumped Soviet-era nuclear subs by Alexey Pavlov and Charles Digges (email@example.com) MURMANSK – Two derelict Soviet-era nuclear submarines lying at the bottom of the Barents Sea present a real radiological risk to surrounding waters and could have a negative impact on the delicate ecosystems of Arctic Seas, leading Russian scientists and Russia’s Ministry for Emergency Services have said. April 3, 2014 by Bellona
The long dormant conversation about raising the subs has been reanimatedbecause of the recent joint workshop held by Russian state nuclear corporation Rosatom and Bellona last month in Murmansk, where the Russian side expressed its wish to see the vessels retrieved.
Yet, the subs are hardly all of the radioactive hazards languishing at the bottom of the Kara Sea.
According to the Norwegian Radiation Protection Authority (NRPA), other submerged radiation hazards include 19 ships containing radioactive waste; 14 nuclear reactors, including five that still contain spent nuclear fuel; 735 other pieces of radioactively contaminated heavy machinery and 17,000 containers of radioactive waste.
Bellona Murmansk director Andrei Zolotkov said an international dialogue about raising radioactive Russian military machinery 20 years ago would have been impossible.
But the overwhelming tally of international cooperative successes on radiological and nuclear hazards in Northwest Russia are, he said, immeasurable. As such, the conference has opened the door for a joint Norwegian-Russian inspection, particularly of the K-159 submarine, later this year………
The radiological archipelago
The Bellona-Rosatom workshop reinvigorated discussion about radiological research surrounding the Novaya Zemlya archipelago, were the Soviets scuttled tons of solid radioactive waste and vessels containing spent nuclear fuel.
The task of past expeditions to this Davy Jones’ locker of radioactive debris has been to inspect sunken reactor cores, ships and containers of solid radioactive waste for leaking radionuclides, as well as to search out other radiation hazards that have not been charted – something Korolyov told the international gathering.
“We have to continue searching for what is lost,” he said, and citing that previous searches for barges loaded with reactor chambers have been unsuccessful, though they are assumed to be in the waters surrounding Novaya Zemlya…….. http://bellona.org/news/nuclear-issues/2014-04-russia-norway-urge-raising-dumped-soviet-era-nuclear-subs
Radio: “Surprisingly, high concentrations [of Fukushima cesium] found in Vancouver area” since ocean currents slow down — Levels are increasing — “Might be hotspots where radiation concentrates” — “Chances are high for marine life to absorb it… concern about mussels… clams, oysters” (AUDIO) http://enenews.com/radio-surprisingly-high-concentrations-fukushima-cesium-found-vancouver-area-because-movement-ocean-currents-june-last-year-increasing-levels-found-be-hotspots-radiation-concentrate-chances-h?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+ENENews+%28Energy+News%29
Joseph Lopez, reporter: In the Vancouver area, as of June last year […] there are increasing levels of cesium-134, the same isotope released from Fukushima. [...]
Irene Querubin, host: I hope we’re not slowly dying by that.
At 7:00 in
Lopez: There’s a strong current called the Kuroshio current […] these are highways in the ocean […] it’s one of the strongest water currents […] and this current passes through Fukushima but it is so strong it helps keep the radiation levels in the Fukushima area lower, it blows it away. […] These radioactive isotopes, in a slower speed — because they’re slowing down in these areas like Vancouver […] where the water is not as fast as in the ocean, there’s a chance for the radioactive isotopes to settle down and be in the water and possibly be absorbed by bottom feeders. [...] The radioactive isotopes [are] not observed much in Japan, in the Fukushima area, surprisingly […] but the current pulls it away and acts as a boundary because it’s so fast. Once the speed slows down in our area, the chances are high for the marine life to absorb it.
At 11:00 in
Lopez: They’re not doing any testing right now, that’s why the public should be concerned [...] We don’t know why they’re not doing it. They should be doing it. [...] It is true that the Pacific Ocean will dilute the radiation, but what they found is there might be hotspots where this radiation might be concentrated. And surprisingly the high concentrations have been found in the Vancouver area because in these waters there’s less movement, less speed. [...] I’m surprised that Dr. Smith of the Department of Fisheries and Oceans would categorically state that there’s a zero chance of starfish die-off [being related to radioactive contamination]. It’s like saying the Titanic will never sink. [...] I would be concerned about mussels as well [...] and clams and oysters, because they are filters. [...] Remember no level of radiation is ever safe.Full broadcast available here
The 6,840 tonne British registered ship, owned by Warrington, UK based Pacific Nuclear Transport, sailed from Barrow-in-Furness, north of Liverpool, bound for Japan on 14 February 2014
The Japan Times reported in January, 2014 that 28 canisters of high-level radioactive waste, produced through the reprocessing of spent Japanese nuclear fuel in Britain, would be transported to the Aomori Prefecture on board Pacific Grebe.
The 28 canisters of vitrified radioactive waste included 14 for Kansai Electric Power Co and seven each for Chubu Electric Power Co. and Chugoku Electric Power Co.
The paper also reported in January that the shipment was the third involving vitrified radioactive waste to be brought to Japan from Britain.
Japan has received 104 canisters of such waste from Britain and plans to receive around 800 more. The 104 canisters have been stored at a facility in the village of Rokkasho, The Japan Times reported.
School Science Project Reveals High Levels Of Fukushima Nuclear Radiation in Grocery Store Seafood Investment Watch By Michael Snyder March 27th, 2014 A Canadian high school student named Bronwyn Delacruz never imagined that her school science project would make headlines all over the world. But that is precisely what has happened. Using a $600 Geiger counter purchased by her father, Delacruz measured seafood bought at local grocery stores for radioactive contamination. What she discovered was absolutely stunning. Much of the seafood, particularly the products that were made in China, tested very high for radiation. So is this being caused by nuclear radiation from Fukushima? Is the seafood that we are eating going to give us cancer and other diseases? The American people deserve the truth, but as you will see below, the U.S. and Canadian governments are not even testing imported seafood for radiation. To say that this is deeply troubling would be a massive understatement.
In fact, what prompted Bronwyn Delacruz to conduct her science project was the fact that the Canadian government stopped testing imported seafood for radiation in 2012…
Alberta high-school student Bronwyn Delacruz loves sushi, but became concerned last summer after learning how little food inspection actually takes place on some of its key ingredients.
The Grade 10 student from Grande Prairie said she was shocked to discover that, in the wake of the 2011 Fukushima nuclear disaster in Japan, the Canadian Food Inspection Agency (CFIA)stopped testing imported foods for radiation in 2012.
And what should be a major red flag for authorities is the fact that the seafood with the highest radiation is coming from China… Armed with a $600 Geiger counter bought by her dad, Delacruz studied a variety of seafoods – particularly seaweeds – as part of an award-winning science project that she will take to a national fair next month.
“Some of the kelp that I found was higher than what the International Atomic Energy Agency sets as radioactive contamination, which is 1,450 counts over a 10-minute period,” she said. “Some of my samples came up as 1,700 or 1,800.”
Delacruz said the samples that “lit up” the most were products from China that she bought in local grocery stores.
It is inexcusable that the Canadian government is not testing this seafood. It isn’t as if they don’t know that it is radioactive. Back in 2012, the Vancouver Sun reported that cesium-137 was being found in a very high percentage of the fish that Japan was selling to Canada…
• 73 percent of the mackerel
• 91 percent of the halibut
• 92 percent of the sardines
• 93 percent of the tuna and eel
• 94 percent of the cod and anchovies
• 100 percent of the carp, seaweed, shark and monkfish
So why was radiation testing for seafood shut down in Canada in 2012?
Someone out there needs to answer some very hard questions……..http://investmentwatchblog.com/school-science-project-reveals-high-levels-of-fukushima-nuclear-radiation-in-grocery-store-seafood/
School Science Project Reveals High Levels Of Fukushima Nuclear Radiation in Grocery Store Seafood Investment Watch By Michael Snyder March 27th, 2014 “……..Meanwhile, PBS reporter Miles O’Brien has pointed out the extreme negligence of the U.S. government when it comes to testing seafood for Fukushima radiation. The following comes from a recent EcoWatch article…
O’Brien also introduces us to scientists from the Woods Hole Oceanographic Institute who have been testing waters around the reactors—as well as around the Pacific Rim—to confirm the levels of Fukushima fallout, especially of cesium.
These scientists are dedicated and competent. But they are also being forced to do this investigation on their own, raising small amounts of money from independent sources. They were, explains lead scientist Ken Buesseler, turned down for even minimal federal support by five agencies key to our radiation protection. Thus, despite a deep and widespread demand for this information, no federal agency is conducting comprehensive, on-the-ground analyses of how much Fukushima radiation has made its way into our air and oceans.
In fact, very soon after Fukushima began to blow, President Obama assured the world that radiation coming to the U.S. would be minuscule and harmless. He had no scientific proofthat this would be the case. And as O’Brien’s eight-minute piece shows all too clearly, the “see no evil, pay no damages” ethos is at work here. The government is doing no monitoring of radiation levels in fish, and information on contamination of the ocean is almost entirely generated by underfunded researchers like Buesseler.
Fishing for data in the radioactive waters off Fukushima It is the job of the authorities to keep us safe, and the Fukushima nuclear disaster was the worst nuclear disaster in human history.
So why aren’t they doing testing?
Why aren’t they checking to make sure that this radiation is not getting into our food chain? Continue reading
|Scientists Expect Traces of Ocean Radiation Soon Science Tech By Jeff Barnard
The March 2011 tsunami off Japan flooded the Fukushima Dai-Ichi nuclear plant, causing radiation-contaminated water to spill into the Pacific. Airborne radiation was detected in milk and rainwater in the U.S. soon afterward. Now, scientists are using a network of volunteers to measure radiation at beaches along the U.S. West Coast.

Nuclear Waste Sits on Ocean Floor U.S. Has Few Answers on How to Handle Atomic Waste It Dumped in the Sea By JOHN R. EMSHWILLER and DIONNE SEARCEY WSJ Dec. 31, 2013 More than four decades after the U.S. halted a controversial ocean dumping program, the country is facing a mostly forgotten Cold War legacy in its waters: tens of thousands of steel drums of atomic waste.
From 1946 to 1970, federal records show, 55-gallon drums and other containers of nuclear waste were pitched into the Atlantic and Pacific at dozens of sites off California, Massachusetts and a handful of other states. Much of the trash came from government-related work, ranging from mildly contaminated lab coats to waste from the country’s effort to build nuclear weapons.
Federal officials have long maintained that, despite some leakage from containers, there isn’t evidence of damage to the wider ocean environment or threats to public health through contamination of seafood. But a Wall Street Journal review of decades of federal and other records found unanswered questions about a dumping program once labeled “seriously substandard” by a senior Environmental Protection Agency official: Continue reading
