[…] The main body of radioactive surface plume of which activity exceeded 10 Bq m−3 travelled along 40° N and reached the International Date Line on March 2012, one year after the accident. A distinct feature of the radioactive plume was that it stayed confined along 40° N when the plume reached the International Date Line. […]

A distinct feature of the radioactive plume was that it stayed confined along 40 N when the plume reached the International Date Line, as stated in Sect. 3.2. The radioactive plume travelled 1800 km (from 160 E to 178 E) for 270 days (9 months) (Fig. 5); therefore, an average zonal speed (u) of the surface radioactive plume was calculated to be about 8 cm s−1 which was consistent with the speed of the reported surface current of 4–16 cm s−1 in the region (Maximenko et al., 2009). […]

We can also assume that the Fukushima radioactive plume moved with surface water […]

  • I thought there were various currents and such. My knowlege on this is very limited but why would the radiation plume follow a complete straight line?


      think Mark, they're projecting an average path for the plume…

    • Jay

      " Moving With surface water " ? Isn't it Part of the surface water ?

      So why is it 'strange' when those water currents , speed and direction are not much different than other years ?

      But wait until it hits California coast : will it stay on the surface and spread sideways , or it will mostly Submerge into the colder deeper waters ?
      This scans bets on 'submerge' :

    • Time Is Short Time Is Short

      It's all BS, trying to avoid responsibility for the ocean current spreading the radiation in a wide plume.

      Take a look at the authors:

      M. Aoyama, Meteorological Research Institute, Tsukuba, Japan

      M. Uematsu, Atomosphere and Ocean Research Institute, The University of Tokyo, Kashiwa, Japan

      D. Tsumune, Environmental Science Research Laboratory, Central Research Institute of Electric Power Industry, Tokyo, Japan

      Y. Hamajima, Institute of Nature and Environmental Technology, Kanazawa University, Kanazawa, Japan

      We've gotten honest answers from them when?

      The plume looks like this:

      The debris is carried by – wait for it – SURFACE CURRENTS!

      • HoTaters HoTaters

        TIS, good post. Am wondering though if the movement of the debris is primarily wind driven, hence the west to east movement.

        Am thinking whatever is in the water column would not move in a neat west to east direction.

        Great link, though, thanks. I'm going to add that to my library, Good find.

        Yes, it is BS designed to deflect the truth…the pier from Japan washed up on the Oregon coast over a year ago…the radiation is already here, the kids are already swimming in it, etc. for over a year…maddening.

        Genocide. Ecocide. How can every government in the entire world stay silent about this? How is there not one whistleblower nation? Not one? How is that even possible? To stand by as the Pacific Ocean itself is destroyed?

        How is it possible to have such a total conspiracy of silence?

      • ToBeExpected ToBeExpected

        Truth is not something that most can deal with especially about a scandal as big, as humongous as this. I don't know how these guys can sleep at night if all they tell is lies and seek to cover up the real truth. I think also, as the effects of the radiation aren't immediately visible, or felt, in the USA and elsewhere, the majority of people are not alerted … even by their own experiences, so it can be talked about openly – a bomb goes off, Fukushima explodes, we ALL know about it…. but the after effects? Just like x-rays, it's the ostrich syndrome / reaction…"Till it effects me, if ever, I won't be concerned.." What a selfish world we live in.

      They've been dumping in the ocean for decades.

      From an IAEA report:

      — For 48 years (from 1946 to 1993), 14 countries used more than 80 sites to dispose of approximately 85 PBq of radioactive waste

      — Solid waste, liquid waste, reactor compartments of nuclear submarines, ice breakers, and nuclear reactors with and without fuel were dumped into the ocean

      — In the North Atlantic, tritium alone represents one third of what was dumped. The rest is Strontium-90, Cesium-134, Cesium-137, Iron-55, Cobalt-60, Iodine-125, Carbon-14, Americium and Plutonium.

      — Beginning on page 32, see maps showing which countries dumped how much and where.

      — Map on Page 69 shows where they dumped off the EAST coast of the U.S.

      — Map on Page 72 shows where they dumped off the WEST coast of the U.S.

      — Map on Page 43 shows where they dumped off Japan's coast

      — More maps show where they dumped off the coasts of the Arctic, France, Spain, the UK, Russia

        Then we all need to get them to monitor everything all the time and then we can all see in highly detailed real-time how quickly our demise is progressing around the world. Will it show you where that airborne bit of mox is floating by in relation to your left nostril? We could all meet On the Beach later to compare readings.. we all c have checked the site(s) you post results on. I wish their traffic would grow. We all know we are ingesting lethality constantly.

Just "my observation" but you obviously have way more knowledge about everything, assuming "plutonium is everywhere" so why don't you go watch some tv and pretend that everything is "what it is" you have no real motive to "understand" anything, obviously.

    40 degrees North Latitude makes landfall near the point just south of the Punta Gorda Lighthouse. That;s in the Kings Range, just north of Fort Bragg, and just south or Petrolia, CA.

    Having lived in that area for 14 years recently, I'm saddened to hear it lay squarely in the path of the incoming pollution from Fukushima.

    I have to question, however, that the water kept its course right along the 40th degree of Latitude. How was that determined? The ocean currents don't travel in a neat west-east direction, so how did those doing the study arrive at that conclusion? It just doesn't sound logical. Too simple an explanatiion, IMHO.

    I'd have thought the Kuroshio current would have carried the radiation northward, where it would have been picked up on the Pacific currents, traveling roughly clockwise toward the Kuril Islands, then the Aleutian chain, then southward along the coast of North America. That's the direction of travel of the currents.

    Can anyone explain why they think the study came to this conclusion? IMHO it's too simple an explanation, but I am not an oceanographer,

  • It's all bogus… the mix of radioactive content caused desalination… and that's easy to track from orbit.. I posted plots of this, and a link to where it's mixed right off the coast of Japan. So, you can just forget the whole "Minimalistic" idea that it remained confined in any way! This is what has all the sea life that can't live in fresh water on the run! As like frogs in slow-heated water.. the dual-environment type stay and die of radiation poison effects.

    The lower life is or has died already, so this is a case of starvation being added to the problem. This radiation mixture kills-off the very bottom of the food chain.. so it will slowly make it's way to us at the top. Better start looking into low-intake diets that still give you enough to survive.

    • We Not They Finally

      Radioactivity causes DESALINIZATION?? If that's true, then does it not also increase global warming?? We didn't swallow the carbon story anyway (although no one wants pollution) with so much more dangerous out there. Just didn't know that radioactivity causes desalinization. That's VERY interesting/scary.

  • mtc02g mtc02g

    This is horrible that the radiation is making its way to California. But that is how the earth will reduce the radiation, by disseminating it across the globe. I wonder if products coming from Japan are irradiated? Luckily the products my business sells come from Hong Kong, but it is close to Japan, could they be irradiated too? I deal with the products all the time, I am worried about getting radiation does. Since they come from halfway around the world I am very meticulous to wash my hands after opening and handling the shipping crates, since they are dirty, but what about radiation, how do you clean that off if it is there?

    • Lion76 Lion76

      If you want peace of mind, the best way is to invest in a nice radiation detector and "know for sure" even though some people on this site will make fun of you for seeking knowledge over assumption don't let that affect what you know your gut is telling you. There is only one way to "be sure" and what anyone else is suggesting you do by ignoring reality is delusional at best.

      I recommend the inspector alert + which is the model I have, it's a good semi-pro level detector. If you want to be more sure and spend a little more, get a detector that has spectrum analysis built into it.

      • We Not They Finally

      I see aloe vera juice mix products from Korea in Costa Rica and do not buy them because there is a strong possibility the products are contaminated because of the source

      This lab does some instructional videos on testing foods that you should research Radiation Food Lab. Hundreds of food and drink radiation tests from ten countries are conducted and compiled

      You really need to know if your products have radiation – I would not want to ship contaminated foods for people to eat/drink. Be safe – have your company do some testing. You may need to source the ingredients of your products from somewhere else.

      Really, though – all nations ought be testing food/drink products and banning contaminated products.And they ought to immediately publish their test results as well.

      The geiger tests that does in Japan show that wood benches at bus stops retain higher levels of radiation than the ground – think the radiation soaks into wood. Wood shipping crates may not be safe. Geiger them too. Testing is the only way you will know. Good luck.

    best "mapping" of the plume will come from citizen radiation watchdogs.. we know, the jet streams do not adhere to one direct line, parts get split off, some drop in some places more than others, there may be a higher set of readings along the 40th degree… but, ESRL PSD map room and El Dorado County Pacific wind loop tells a better story, as many of you here already know.

    The Japanese limits are based on the assumption that 50% of nationally distributed foods are contaminated


    A suggestion of a member to introduce additional values for food corresponding to non-accidental situations,such as releases of radioactive effluents,was not supported, as it was noticed that such releases are under regulatory control.


    One member suggested reconsidering the previous situation of the GLs in 1989 with a single food category, as that was protective of both infants and adults. Other members of the eWG did not support this proposal, stating that society expects infants and young children to receive better protection.Another member proposed to add the category of dairy foods. There was also no support for this suggestion. Both members withdrew the proposals

      Frightened, intimidated politicians deciding what is "safe." The same bad news re-packaging itself.

  • We Not They Finally

    Does anyone know if this is parallel to the Kuroshio current? That might explain it's keeping within a certain path.

  • We Not They Finally

    Some scientists, like Ken Buessler (Woods Hole Institute)are NOT sounding an alarm, because the isotopes will be "diluted" in the huge Pacific before arrival. But this is myopic, really maddening. Because EVEN IF the first wave to arrive here is "diluted," this is a wave that never ends!! Just because the initial releases were "REALLY bad," hardly means that what's been coming after is "better." We've never had three complete melt-throughs ever before. And now highly contaminated water will be ROUTINELY dumped into the Pacific by TEPCO. And how nice if radioactivity just "diluted" itself away in our bodies, as well as the ecosystem. But it's doesn't. It's CUMULATIVE.

    • Lion76 Lion76

      they still rely on "background/external" dose rates, too. Where is the chart showing what "internal/ingested/inhaled" dose rates are?


      Because as far as I know… this is just another stage of "denial" just like those that want to bring up "the sun" when talking about fukushima radiation…. Obviously, these are not the same and entirely different on a 'particle' level.

    I have worked on pacific radiation reporting with Ken Buessler (Woods Hole Institute).HE IS DOING ALL HE CAN. Without funding, Ken is using all assets he can find to assist. We have a group of sailors out with KI4U dosimeter badges; ken has made suggestions, and helped with our reporting. While vessels in Fiji, Marshall Islands, Guam and other West Pacific islands have NOT shown elevated (yes the badges accumulate) radiation results, Ken has tested tsumani and beach debris we have sent him. He also got volunteer vessel or Ships of Opportunity in the oceans off Japan and in the potential current area to collect data; nothing has been elevated to my knowledge. KI4U has tested vessel filters/air and engine, as well as the matching badges. So far for that area, and one vessel which has transited from Fiji to Canada, no elevated radiation has been identified. Ken is the ONLY contact we have found to pay attention. Now if he could be provided funding or a grant-or other institutions are interested, am sure we can provide vessels for testing and providing data. Ken is doing all he can, and needs appreciation, not complaints and comments critical of his efforts. Fund a project!
