Since the Tohokuearthquake and tsunami crippled Japan's Fukushima Daiichi nuclear power plantin 2011, concerns have spread among the public that water with traces ofradioactive material might be traveling in a plume across the Pacific Oceantoward the west coast of North America.


Experts say theradiation levels reaching the U.S. coast and Hawaiian Islands will be too lowto threaten human health or marine life, but no U.S. governmentor international agency is actually monitoring radiation in these places.


Now, a scientist atthe Woods Hole Oceanographic Institution (WHOI) in Massachusetts is launching anew citizen science project to measure levels of radioactive cesium in waterwashing up along the West Coast.


"The levels ofcesium in the ocean we expect of the west coast of North America are not ofconcern for our own exposure or fisheries," said WHOI marine chemist KenBuesseler, who is leading the project. But whether people agree with thesepredictions or not, radiation levels should be monitored to confirm them, Buesselertold LiveScience.

“我们预计北美西海岸海洋中放射性铯的水平,对我们自己以及渔业来说,不会使人担心。”WHOI海洋化学家Ken Buesseler说道,他主持了这个项目。但是无论人们是否认同这些预测,放射性水平都应该被监测从而被确定,Buesseler告诉《生命科学》。

A recent study suggests the radioactive plume fromFukushima will reach U.S. coastal waters this year, peaking in 2016. But oceancurrents off Japan's eastern coast have most likely diluted the radioactivityto well within safe levels set by the World Health Organization, said studyleader Vincent Rossi, an oceanographer and postdoctoralresearch fellow at the Institute for Cross-Disciplinary Physics and ComplexSystems in Spain.

最近一个研究表明来自福岛的放射流将到达美国海岸,并在2016年达到峰值。但是Vincent Rossi,一个海洋学家,也是西班牙跨学科物理和复杂系统研究院的博士后研究人员,又说道日本东海岸的海流会将放射性物质稀释到WHO规定的安全范围内。

Buesseler startedsampling the seawater around the Fukushima plant — sometimes from as close as ahalf mile away — three months after the disaster. His team has dozens of watersamples from the coast of Japan to the middle of the Pacific, but needs samplesspanning the rest of the Pacific to the West Coast. He launched a websiteJan. 14 called "How Radioactive is Our Ocean?", where the public canmake tax-deductible donations to support the analysis of existing samples orpropose and fund new sampling locations along the West Coast.


Collection andanalysis of a seawater sample costs $550 to $600, depending on the site'slocation. The scientists are asking individuals or communities to donate aminimum of $100 in seed funding, and WHOI will create a fundraising website foreach location that is selected for sampling.


When a person or groupraises enough money, WHOI will send a sampling kit so volunteers can collectabout 5 gallons (19 liters) of seawater and ship it back to WHOI for analysis.


The scientists willuse a $75,000 instrument to detect levels of biologically hazardous gamma-rays,produced by the decay of radioactive cesium in the samples. The results of theanalysis will be posted on an online map, showing cesium concentrations and thenames of sponsors.


The oceans alreadycontain naturally occurring radioactive chemical elements, as well as remnantradiation from nuclear-weapons testing during the 1950s and '60s. Scientistscan take a fingerprint of the Fukushima radiation by precisely measuring theratio of the chemical variant cesium-137 left by weapons testing, which has a30-year half-life, to the chemical form cesium-134 from Fukushima, which has atwo-year half-life. (Half-life is the time it takes for half of the material toradioactively decay.)


The U.S. safety limitfor cesium levels in drinking water is about 28 Becquerels (Bq), the number ofradioactive decay events per second, per gallon (7,400 Bq/cubic meter). Forcomparison, uncontaminated seawater contains only a few Bq/cubic m of cesium,and much higher levels of other, naturally occurring radioactive elements.


In a separate project,known as Kelp Watch 2014, researchers plan to monitor radiation in California'skelp forests.


"Part of thereason for doing this is because the public is very freaked out by all thistalk of radioactivity,” the study's leader, biologist Steven Manley ofCalifornia State University, Long Beach, told KQED Science. “If they canactually see the numbers and a commentary as to what they mean, hopefullythat’ll put them at ease."

“做这个项目的部分原因是公众谈核色变,”这个研究的主导者,来自长滩加利福尼亚州立大学的生物学家Steven Manley,告诉旧金山公共广播电台科学栏目。“如果他们看到放射性物质的实际含量以及了解它们代表的意义,希望这能让公众放轻松。”

All nuclearcountries use the same nuclear manual that tells them to minimize radiationdangers using statements like these:
– there is no direct harm
– no immediate harm

所有的拥核国家使用相同的核手册,用下面这样的声明来最小化核恐慌: --没有直接伤害 -不会立即产生伤害

There are severalnuclear monitoring sites that are reading high levels of radiation on the Westcoast. Of course the media is not going to tell anyone this because they aretoo busy giving us the fluff instead of the truth!


Why not just addsome instruments to all the bouy's already in place used for weather,, watertemps and wave heights. The real problem is not about how diluted the radiationhas gotten,, it is about what it did before it became so diluted, where wasthat in the oceans and how did it affect the fish populations that getharvested for food? What about their food chain? Fish can feed in all differentareas of the Pacific as they migrate. What about the food? Not just the water!


Professor Kakusays this has already affected New York's cow milk but not to a level ofconcern. Well, for sure Hawaii and California's cow milk should also be testedsense the west coast is the first to be fouled by nuclear waste, from Japan!The professor also confirms that Fukushima's nuclear accident is equal toRussia's Cher nobles nightmare. The Professor says just think of this we eachnow have a little bit of both these major nuclear blasts in all of us! This ismind boggling.


Lawmakers seekdata on sailors' exposure to Fukushima radiation
Jan. 14, 2014 Military Times
House and Senate want answers on whether United States Ship sailors receivedradiation while supporting humanitarian operations in Japan following theFukushima disaster.

国会议员寻找暴露于福岛辐射中的海军士兵数据 2014年1月14日 军事时报参众两院希望得到答案,美国船上的海军战士参与日本福岛灾难的人道主义救援时是否受到核辐射。

Done reportsbefore about this, even some scary stories of how certain fish whereradioactive. When different studies had been done they all pointed out theradioactive levels from it in the fish was so low, that a banana had moreradioactive content.

It is past timefor the Japanese to tell the truth about the amount of radiation leaking intothe ocean and the air. We know somewhat of the path it takes by the itemswashing up on shore in Hawaii, Oregon, Washington, etc. All countries seem todiminish the affect radiation has on people when they don't really know theamount being leaked. We know from fish samples that the radiation found in mostfish from the Pacific that is consumed by humans is at least twice what it wasbefore the tsunami. This is a global problem and if the Japanese government needs assistance they should ask for same.

I must start off by saying that I am Japanese,and I regret that the Fukushima Disaster caused by a major natural disaster,has not been truly contained yet. It affects us all, and I am sorry. That beingsaid, I do not understand the need for crazy blatant lies some sites publish,and the fact that some good part of the general public are gullible enough tojust believe anything they read on these interwebs and stupid stories theyshare on facetube worries me. Don't people understand that people actually havebeen living in Nagasaki and Hiroshima after the bombs dropped without everybodygrowing an extra arm and turning into a human nite-lite?Yes people die from radiation poisoning and it does get handed down to theyounger generation to some degree, but all this fear mongering is just absurd.

Fukushima accidentwas caused by a natural disaster. Do you know of the 2000+ nuclear tests theworld has seen, many of the earlier ones took place in the atmosphere(land and sea).Does anyone really understand the effect the fallout from those tests rank, incomparison to Fukushima? These "tests" were for militarypurposes(deliberate) and I think they are ethically worse than power planthaving an accident after behing hit with a catastrophic earthquake and tsunami.Especially bad are the 2 countries who didn't sign the agreement banningatmospheric testing and just continued to do so, yes I'm looking at you Chinaand France. Oh wait we mustn't forget all the nuclear subs, bombs, warheads,nuclear satellites that were oops, dropped, lost, fell from space.... Youwouldn't believe how many broken arrows there are.

If anyone canactually list all the nuclear incidents (both military and civillian) on ascale of how much radioactivity harming the environment, and our health, Iwould be most interested to see it.
