VICTORIA -- Radiation from the leaking Fukushima Daiichi nuclear reactor has been detected on the shores of Vancouver Island, four years after a deadly earthquake and tsunami in Japan killed 16,000 people.
University of Victoria chemical oceanographer Jay Cullen said Monday that it's the first time radiation has been found on the shorelines of North America since the quake and tsunami ravaged the Japanese north coast and disabled the nuclear reactor.
Low levels of the radioactive isotope Cesium-134, which scientists say can only come from Fukushima, were found in waters collected on Feb. 19 off a dock at Ucluelet, B.C., about 315 kilometres west of Victoria, said Cullen.
Last November, the first sample containing detectable radioactivity from Fukushima was discovered 150 kilometres off the coast of northern California.
Over the past 15 months, scientists and citizen volunteers have been collecting water samples at more than 60 sites along the Canadian and U.S. west coasts and in Hawaii as they've looked for traces of radioactive isotopes from Japan.
"This is the first sample that's been collected in North America with this contaminated plume of sea water, which we've seen offshore, but it's the first time we've actually seen it at the shoreline," Cullen said.

4.2.3 Characteristics of Plutonium Contamination
There are few characteristics of plutonium contamination that are unique. Plutonium
contamination may be in many physical and chemical forms. (See Section 2.0 for the many
potential sources of plutonium contamination from combustion products of a plutonium fire
to radiolytic products from long-term storage.) [font color="blue"]The one characteristic that many believe is
unique to plutonium is its ability to migrate with no apparent motive force. Whether from
alpha recoil or some other mechanism, plutonium contamination, if not contained or
removed, will spread relatively rapidly throughout an area. [/font color]

Particulate / "hot particles"... no.
Such are common from nuclear explosions, and likely to some degree from Chernobyl... but not from Fukushima (where the releases were almost exclusively volatile elements escaping as gases).

(40,416 posts)1. No. (Obviously!)
2. No, the amount reaching North America is thankfully tiny. In spite of all the problems, thankfully the Pacific Ocean is ginormous. And in spite of all the screeching by those who apparently only want to set people's hair on fire by making shit up about this. (E.G., sea stars)
3. Probably only near Fukushima, since these are not long-lived isotopes which is precisely how they knew that these measurements were from Fukushima. All longer lived isotopes are below background, in other words, not a detectable danger.
4. Of course, but this seems like a straw man. Nobody says we should not be careful. And in hindsight, Fukushima probably should not have been built how and where it was. So the question remains, what do we do about it now? All other questions and post hoc hand-wringing become moot. Except the lessons to be learned, that is. It is a bit late to not build Fukushima.
I've learned by my mistakes and I can repeat them exactly.

FBaggins
(26,721 posts)1 - I'm sure they wish it were somewhere else... but it really wasn't the siting that was the problem that really did the units in (or even height of the seawall). We could talk about unit design and that newer designs would not have melted down... but that wasn't available to them at the time.
What was available to them was the level of emergency planning that US reactors of the same era have to comply with. Things like waterproof bunkers for backup generators... replacement generators stored in safe locations that can be brought in... standardized connectors so that you don't end up with backup power that can't even be connected when the time comes... and (most of all) practice drills that actually bring in generators and connect them up.
They survived the earthquake... and even the tsunami strike. It was the loss of power that did them in, and that's something that regulators should have stricter controls in place for.
2 -Seriously? Did you expect anyone to say that it's a good thing? The ongoing releases are negligible compared to the initial release... but even those are not "good things"
3 - Of course (about 1,000 times higher IIRC)... and it was MUCH higher than that back in 2011. This is really the one for you to look at. Take a look "up the food chain". Bioaccumulation happened in some species, but the levels fell off pretty rapidly. There are literally hundreds of thousands (if not millions) of datapoints for crops, livestock, and seafood... and the remaining significant contamination for seafood is almost exclusively the bottom-feeders that are still in contact with high contamination levels on the sea floor.
4 - Oh come on. Seriously?

Just the opposite. Insisting on people rejoining the rest of us in reality and accurately assessing what has really occured... is a necessary prerequisite for considering the future. I think, for instance, that a proper consideration for the future should involve understanding that the evacuations and coincident substandard housing conditions have already killed far more people than returning once the threat of sustained criticality and additional core damage was past. I think that a proper consideration for the future would include a better understading of the health and climate impacts of the billions upon billions of dollars in additional fossil fuel burning due to a national shuttering of nuclear plants (not to mention the extreme economic impact just at a time when they were exiting their decade-long recession and now have so much necessary rebuilding that the money could have been spend on).
I think the proper consideration for future generations is to increase the amount of nuclear and renewable generation substantially... until no coal or oil gets burned at all, and only enough natural gas to back up the variable generation of renewables that couldn't otherwise be covered by surplus baseload nuclear/hydro.

(13,685 posts)The world looks forward to a better plan for the nuke waste.
The only plan now is to bury it and find a way to warn future generations of where we buried it.
Currently we see that Fukushima has lost control of its waste. And now that waste is being found on our west coast. Sure, 'future planners' such as yourself said it would never reach the US and Canada, but here it is. So we must look at whether 'planners' such as yourself have any credibility. And the verdict is: NO. No credibility.

(18,652 posts)Well, first the highly radioactive spent fuel rods were going in pools of water to keep them cool until a suitable home could be found. But no one (and I'll bet that includes YOU) wanted them in their backyard, not to mention traveling around the country to get there. Then Congress found a suitable home at Yucca Mt. in Nevada, which likewise even Las V. residents did not want and they're 100 mi. from the site. So the rods have sat in these old pools since the 1970's, just waiting for a disaster (earthquake, pump failure, whatever) to happen and contaminate a large area.
So, yeah, good planning. As for the future, I'm sure our descendents will be very happy that we left them with highly radioactive materials sitting around in old pools.

(387 posts)Cs-137 has a half life of 30 years.
Besides, the article is talking about about Cs-134, which has a half life of 2 years.
Buzz Clik
(38,437 posts)The article mentioned 134Cs because it could only come from Fukushima. Why? Because 134Cs has a radiological half-life of 2.06 years, and 134Cs from any other sources would have long decayed away.
134Cs will not appear in the absence of 137Cs; the 137Cs will be there, too, but because of its longer radiological half-life of 30.2 years, 137Cs could be coming from a number of other sources.
The biological half-life of 137Cs is identical to that of 134Cs, a matter of a few short months. Therefore, given the very short biological half-life of both isotopes of isotopes compare to their radiological half-lives, it is a safe assumption that neither will bioaccumulate to any extent in humans.
Are we clear now?

(13,685 posts)True, some science says that cesium resides in the body around 70 days.
But what must be recognized is that since cesium is everywhere, bodies acquire more cesium almost daily.
So the chances of having a decaying cesium atom in your body these days is greatly increased. And for 70 days it has a chance to decay and radiate into your tissue.

If they explain that it has a short biological half-life, my answer is the same.
I'd prefer not to be irradiated from the inside, if it's practically avoidable.

(3,811 posts)My tap water is taken from the Stones River. The Middle Point Landfill is the largest waste landfill in the state of Tennessee. It's situated immediately on the bank of the Stones River, inside of a bend a few miles from Percy Priest Lake, which is the secondary reservoir for our drinking water supply.
Under what's known as the Bulk Survey for Release (BSFR) program, Middle Point Landfill began accepting low-level radioactive wastes from nuclear facilities in Oak Ridge Tennessee in 1997.
How Allied Waste Inc. came to own and operate the largest active waste landfill in the state of Tennessee, and how a Class I permitted landfill came to be located on a river bank just upstream from a major municipal drinking water reservoir is a long story.
We are in the process of moving from opposition within the system to a more confrontational approach, but that too, is another story.
Buzz Clik
(38,437 posts)Allied either established their site before the new regs or somebody was totally asleep at the wheel. Just a hint that they are leaking, and they get shut down.
The fact that they are receiving radioactivity is not only crazy it is in violation of federal regulations. RCRA controls waste disposal, and even a Subtitle C (hazardous waste) landfill cannot accept radioactivity.
How is this happening?

There are ample hints that the liners are compromised and leaking, TDEC (Tennessee Department of Environmental Conservation) chooses to ignore or minimize the issue. The multiple gas flares around the site are another potential source of exposure. There are solid, reasonable, and well founded concerns over the siting and operation of this landfill. Government agencies dismiss all concerns with boilerplate language.

(3,811 posts)<<TOXICITY SUMMARY: The element cesium exists in several forms known as isotopes. In nature, cesium exists only as a non-radioactive (or stable) isotope known as cesium-133 (Cs-133); however, there exist several cesium isotopes that are radioactive. The radioactive isotopes of cesium are formed during nuclear fission, in commercial applications such as the generation of electricity at nuclear power plants. The most important cesium isotopes in terms of their potential effects on human health are cesium-134 (Cs-134) and cesium-137 (Cs-137).>>

FBaggins
(26,721 posts)You provided a short clip related to the toxicity of cesium... but didn't compare it to the elements in your body that are also radioactive. TOXNET has them as well... why didn't you check?
Nobody in the world (yes, including Japan at the plant) has seen radiocesium levels high enough that the chemical toxicity of the element is relevant to the conversation (see below for why). The radiotoxicity of a given activity level of Cesium is virtually identical to that of the bulk of your internal radioemiters... because both are producing beta particles (electrons) of roughly the same energy level.
Example for above - One milligram of Cesium 134 produces almost 45 Billion disintigrations per second (Bq). This report says that the CS134 reading was 1.5 Bq per ton of water. So if you consumed an entire liter of seawater, you might have to worry about the salt content, but not the chemical toxicity of the .00000000000003378 milligrams of Cesium 134 that you were consuming.

What they found was cesium 134, with a half-life of about 2 years.
That is itself a breakdown product though, the reactors were not fueled with cesium.
They were using a mix of uranium and plutonium,
which have half-lives in the thousands, millions or billions of years.

"We're more than a thousand-fold below even the drinking water standard in the coastal waters being sampled at this point. Those levels are much much much lower than what's allowable in our drinking water."
Cullen said in a statement that if a person swam for six hours each day in water with Cesium levels twice as high as those found in Ucluelet, they'd receive a radiation dose that is more than 1,000 times less than that of a single dental X-ray.

But here, you still feel the pain and damage around you. Nuclear power is an issue for sure, one that the Japanese talk about and think about.

(3,811 posts)Because until the equipment and safety procedures were worked out, people were harmed and injured by x-rays. In many cases, it's still typical today to leave the thyroid exposed during the procedure, unless the patient specifically asks that it be shielded.
Radiation is dangerous. I have a thyroid disease. So does my mother. I've had a lot of dental x-rays in my life. Are they related? Who knows. Do you?
All radioactive decay processes are not equal. Cesium 134 decay produces radiation of a specific frequency and energy. You might be comfortable with official claims of the relative safety of certain kinds of radiation, but I think it's prudent to consider such claims as speculative.
FBaggins
(26,721 posts)Radiation is all around you, but there are levels that simply don't present an issue.
The comparison given in the article was that you could swim in water twice as contaminated for six hours a day every day for a year and it still wouldn't add up to 1/1,000th of a single dental xray dose.
I have a thyroid disease. So does my mother. I've had a lot of dental x-rays in my life. Are they related? Who knows. Do you?
There has been a small correlation between dental x ray doses (particularly with very young patients) and increases in thyroid cancer (and other thyroid disorders)... so it's certainly not outside the realm of possibility (though the chances are very low). There is also, however, a FAR larger correlation to genetic factors. If your mother has it as well, most specialists woud assume that was much more likely.
All radioactive decay processes are not equal. Cesium 134 decay produces radiation of a specific frequency and energy.
Not "frequency" perhaps... but yes, there certainly is something to be said for difference in radiation type (alpha/deta/gamma/etc) and energy level involved. One Bq of radiation from plutonium is not the same as the same activity level of cesium.
However, it's worth noting that the type and energy level of the radiation from Cesium (Beta radiation at a bit over 1 MeV) is virtually idententical to that of Potassium 40... and you have many thousands of those disintigrations occuring in your body every second. Seven more (assuming you could consumer a literal ton of water) is hardly going to make a difference.

(3,811 posts)Or in quantum terms, both the energy and momentum of a photon are proportional to the frequency of the wave.
I might not swim in the ocean 6 hours a day, but the ocean is filled with living things that are there 24/7.

FBaggins
(26,721 posts)You're thinking of electro-magnetic radiation (which does include x-rays).
The nuclear radiation that we're discussing is primarily alpha and beta particles. They have charge and mass, not wavelength.
I might not swim in the ocean 6 hours a day, but the ocean is filled with living things that are there 24/7.
Yep... and for them it's useful to compare that 7 disintigrations per ton of water... to the 10,000+ disintigrations that are already there naturally (most of which are of the same type and energy level as that of cesium emissions). It's also worth noting the far higher amounts of activity from things like nuclear explosions that's still there.
The amount of radioactive cesium, iodine, and other isotopes spread across 4,700 miles of ocean was small, this time. That's a lucky accident.
And that's about the size of it. While the event was significant (the second worst nuclear power disaster)... it simply isn't a health threat to the oceans or mankind in general... and is barely a threat to the people closest to the plant.
cheapdate
(3,811 posts)All particles, including particles resulting from radioactive decay, have both a wave aspect and a particle aspect. Wave or particle models can be used. Depending on the question, one or the other model may be more useful. The wave aspect of particles involves a wavelength inversely proportional to the particle's momentum.
FBaggins

The rest of the conversation, however, stands. There is no rational basis for discussing chemical or radio toxicity of cesium at 7 Bq/ton of water.

That's true almost by definition. It will take decades at least... but we're more than far enough along to tell that it is nowhere close to being as bad as... say... Hiroshima, Nagasaki, Chernobyl, Castle Bravo (just to list a few of the nuclear events).
There has been unprecedented censorship invoked in regards to it.

You have an interesting perspective on things.
Let's not oversimplify the issue beyond all recognition. Ten "Three Mile Island" events wouldn't become worse than Chernobyl just because there were three reactors. The specifics of the incident matter.
and as I posted up thread the head chief of the plant says there is NO technology that can handle the problems
Again... so? That isn't what he said - which was really just that (just as at TMI) they would have to develop the technology once they knew what it had to do. Perhaps one unit can be easily flooded and most of the fuel remains in the RPV... then they can use options very similar to the TMI defueling. Perhaps the one next to it cannot be flooded and they'll have to develop something entirely different that has to operate remotely at a distance. We won't know for years... but none of that tells you that Fukushima is worse than Hiroshima... let alone the hundreds of nuclear explosions that were performed in the Pacific. You say that three reactors melted completely... but almost everything (99.999+%) that melted down is still there in the containment. Hiroshima was in no sense contained... nor could there ever be a technology that could clean it up.

Fukushima is in no sense a global catastrophe. The earthquake and tsunami were a catastrophe for much of Japan... and Fukushima was a catastrophe for the plant and surrounding area... but it was in not a global catastrophe, nor does it present the slightest possibility that it could become one.
The technology to even gauge the extent of the problem doesn't exist
Don't be ridiculous. The extent of the problem is pretty well understood. The specifics of how to clean it up cannot be known for a number of years (and there's a slight chance that it will be impossible). But the extent of the problem (that is, the specifics of the release and potential additional release) are pretty firmly understood.
You drive your car with the oil light on because you're in a storm and don't want to stop. It starts to run rough and warning lights go on all over the place. You pull over and it's clear that the car has overheated and pressure is venting from the radiator nd you can't get the engine to turn over. You're lucky enough to get out of the car just as some flash flooding undercuts the side of the highway and your car slides into a deep ravine (but luckily, out of the water). You call in your mechanic and want to know when you can get the car back on the road and how much it will cost.
He tells you that there's no way to know any of that (or even if it can be fixed) until he can get the engine open and see whether the valves are damaged... or the rings... or the pistons may even be locked in the block and the thing is a total loss. He can't even begin to tell you when he'll be able to answer the question because he doesn't know when/if he can get the ca out of the ravine.
Now... that's not an identical situation, because the mechanic doesn't have to develop new tools to work on the engine once he gets it open, and so many cars have overheated that he knows well what the possible failure points are and how much work is needed in each case... but you would still look pretty silly telling someone else that the technology doesn't even exist to determine what's wrong.
Not to contradict the head of the cleanup, but it isn't as much a technology problem as an engineering problem.

No one knows the location, let alone physical state of the reactor cores and how much radiation they are releasing or have released. Robots sent to look don't return. Ice walls don't work. No place exists to safely store the waste. Untold tax dollars and, more importantly, four years have been wasted on make work and public relations projects. That's also sideshow, but you don't mind.

No way to stop the leaks.
No current technology for a fix.
They continue to dump it into the Pacific Ocean.
They don't even know where the cores are for sure.
fuck..what a mess
Oh yeah and I can see Victoria, BC from my backyard, so I'm taking this very up-close and personal.

FUKUSHIMA--Four years have passed since the Great East Japan Earthquake and tsunami triggered a triple meltdown at the Fukushima No. 1 nuclear power plant in March 2011.
Am I really living in a leading nation of the world? I have been asking myself ever more often after I moved to this northeastern city, capital of the prefecture of the same name, in spring 2014.
At least 120,000 residents of Fukushima Prefecture still remain evacuated. Simply driving along National Route No. 6, which runs north to south across evacuation zones, or in its environs will let you see, whether you like it or not, many telltale objects such as dilapidated houses, a huge number of bags filled with refuse from the decontamination efforts, and debris left in the open.
A joint survey conducted recently by The Asahi Shimbun Co. and Fukushima Broadcasting Co. showed that 69 percent of Fukushima Prefecture residents believed that little or no foundation has been laid for post-disaster rebuilding. That finding is not surprising at all.
Just as disaster areas remain in such a plight, a subcommittee of the industry ministry began meeting on Jan. 30 to discuss what energy sources should be used, and to what extent, to cover Japans electricity demand in the years to come.
I believe Japans (nuclear) safety regulation system has become a global standard, the minutes of the proceedings quote one former industry ministry official as saying during a subcommittee meeting. I just hope the public will fully understand that safety standards that are at the world's top level are now in place.
Those remarks stupefied me.
