## The "more political thread" besides "Japan Earthquake: nuclear plants" scientific one

 Quote by NUCENG Yes, IF they are doing it correctly. Dmytry is discussing Grays and Sieverts and he is right that there is a distinction. A Gray is 1 J/kg of any substance. Sv are 1 J/kg equivalent dose. The links to FGR11 and FGR 12 explain whow a concentration of radiation in a cloud can be converted from Bq/kg, or Bq/cm^3 into an equivalent whole body dose in Sv accounting for inhalation, ingestion or simple external dose from the cloud, liquid, or contamination levels on surfaces. Limits for radiation workers, and the general puplic are expressed in Sieverts. In the United States we had limits on doses to the whole body, skin of the whole body extremities and there are also some guidelines for dose to thyroid and organs like bones and so on. The new standard now in use is TEDE (Total Effective Dose Equivalent). TEDE is the sum of Deep Dose Equivalent (Penetrating dose to the whole body) and CEDE (Committed Effective Dose Equivalent which is a combination of the internal effects of radiation to the organs.
But how accurate are those estimates? We all know them are imperfect; nothing is perfect; and so on and so forth. In science, each number has error range.
When you say it is imperfect, please tell how much do you think it is imperfect. The "imperfect measurement" is a tautology.

In my opinion it's at best 'within same order of magnitude' sort of estimate. The dose near a rain drain can be order of magnitude higher than average [not as dramatically as in the video where Geiger counter is counting betas, but still quite dramatically thanks to inverse square law], the long term inhalation (of the deposited material that re-enters air) is very dependent to the weather, etc. The doses that kids can get, well, god knows, kids play in dirt, some types of dirt chemically absorb Cs-137, some do not. The distribution of radioactivity is a fractal with high 'roughness', there's huge variability down to 1m distances.
Then the food testing, beyond limit food will slip through occasionally [you cant test everything, just randomly chosen samples], how often? How do you know in advance how often? And what is the distribution of the doses? Then, there's the issue of wood ashes... do they use wood for heating at all or not? In the tsunami aftermath? Then there's the issue of the wreckage cleanup work that has to be done. And so on and so forth, and that's the things that i'd guess can change dose by more than factor of 2, and there's probably a lot of other important things I missed. The contamination level of radioactive boars in EU varies immensely - a few boars are heavily contaminated, most are harmless [strongly non-gaussian distribution btw], not a good situation for random sampling based testing.

It is not enough to calculate 'to the best of your knowledge' in science. You need also to provide the error range, and ideally distribution of the errors. In engineering too - I believe you do have ranges for uncertain numbers?

re: Sievert vs Gray, it just irritates me immensely to see a Geiger counter that advertises it's giving out Sv. The bloody thing doesn't even do Grays on gamma very well, the thing overcounts betas - yet it proudly says microSieverts/hour.

 Quote by jlduh Back to a fact (i will express no opinion ) 35 Japanese reactors are soon to be out of line http://www3.nhk.or.jp/daily/english/12_29.html
Interesting. Hopefully they will fix any issues before they come back online. (If they are going to that is.)

More contamination on the grass in towns outside of the evacuation zone, and far outside!

http://www3.nhk.or.jp/daily/english/13_01.html

 3,480 becquerels of radioactive cesium were detected in one kilogram of pasture grass collected on May 5th in Nikko City, Tochigi Prefecture. The figure exceeds the state limit of 300 becquerels. Also, at two different locations in Nasushiobara City, 3,600 becquerels and 860 becquerels of radioactive cesium respectively were detected in one kilogram of pasture grass collected on May 3rd. Tochigi Prefecture requested farmers in the area where the radioactive substance was detected not to feed pasture grass to livestock.
NOTE THAT NIKKO CITY IS AT AROUND 170 kms FROM THE PLANT (SOUTH WEST) which is quite far... the other one is at around 100 kms same direction.

It seems that the winds are spreading the bad stuff in several directions, the North west has been severely touched, the South West could start to get the same scenario.

Over a long period of time (who knows when this crisis will be contained), we can fear that long life Cs-137 (ans maybe Strontium?) will accumulate here and there, like thin layers of small snow falls which would never melt and add weeks after weeks...

The only difference being this is invisible and dangerous snow...

I understand. But the issue isn't that it reads in microSieverts/hour. ANY measurement system will be just as accurate on that device as any other one. The key, I believe, is to make it as accurate as possible.

 But how accurate are those estimates? We all know them are imperfect; nothing is perfect; and so on and so forth. In science, each number has error range. When you say it is imperfect, please tell how much do you think it is imperfect. The "imperfect measurement" is a tautology.
And? The fact is that the system is in use and it works, whether you agree with how accurate it is or not. Is there another way of doing it that works better in that situation?

Your entire post goes off on a tangent about things that aren't remotely close to dealing with counting sieverts on a geiger counter. Do you really think that they never took any of your situations into account when they designed the system and when they use it? Ludicrous!

You might not like the fact that there are error ranges and estimates and such, but in the end it doesn't matter. There isn't any other way of determining these things.

And just to make sure everyone knows my position, I'll say it again.

I think there were serious mistakes made in the running of the NPP's in Japan. I think there are currently and will be more mistakes made everywhere. But my opinion is that the gain is worth the risk as long we err more on the side of caution than we have in Japan.

 Drakkith: What I do not like is that nobody is calculating or reporting the error ranges. There is an other way. Honest science. Where not only you tell the measurements, but you also tell how much (and how often by how much) it can be wrong. Other thing that I do not like is this nonsense discussion where any error - be it off by up to an order of magnitude, be it to 1% tolerance, is equally 'imperfect'. You just don't distinguish between any degree of 'imperfect', and for you it makes absolutely no difference, it's all verbal reasoning from you, is it not? Yes/no, perfect/imperfect (and everything is imperfect), etc. "Do you really think that they never took any of your situations into account when they designed the system and when they use it? Ludicrous!" Do I think they haven't took any? No, they have, some of. Do I think they have took ALL ? No I don't! It is immense amount of work. It is just not doable, period. What is doable though, is a honest estimation of by how much it can be wrong. Hell, even a dishonest estimation of the error range is still a huge step forward compared to 'throw some numbers out and assure them that it is the best measurements that can be done'. "But the issue isn't that it reads in microSieverts/hour. ANY measurement system will be just as accurate on that device as any other one." Suppose you had a ruler that reads in calories, you measure size of the fruit with it. Well, the distance measurements on that ruler can be accurate, but the calorie on that ruler are not. You can, however, use the ruler that reads in centimeters (or inches), with a conversion table (for different fruits), to obtain calories far more accurately.
 jlduh, I have no interest in joining this thread. I'm interested in the technical aspects of Fukushima, not the politics. As such there are aspects of Fukushima that might be compared to Three Mile Island or Chernobyl or SL1 or any number of sites or events. I only wondered if that documentary was considered a "fringe" video made by nutjobs or not. You are living in France so I thought you might have some knowledge of the subject matter. BTW 2, 3 and 4 are each spewing steam at the moment.

It isn't reported because it only serves to confuse almost everyone and cause even MORE panic. The average person doesn't like any possibility of errors, no matter how inevitable they are. (In my experience at least) This doesn't make it dishonest to me. I guess it does to you.

 Other thing that I do not like is this nonsense discussion where any error - be it off by up to an order of magnitude, be it to 1% tolerance, is equally 'imperfect'.

Incorrect. I have no idea why you would believe this. Any errors that are outside of whatever is reasonable given the situation are unacceptable.

 "Do you really think that they never took any of your situations into account when they designed the system and when they use it? Ludicrous!" Do I think they haven't took any? No, they have, some of. Do I think they have took ALL ? No I don't! It is immense amount of work. It is just not doable, period.

Hell, even a dishonest estimation of the error range is still a huge step forward compared to 'throw some numbers out and assure them that it is the best measurements that can be done'.
I disagree. It is entirely possible to accurately calculate reasonable estimates.

 "But the issue isn't that it reads in microSieverts/hour. ANY measurement system will be just as accurate on that device as any other one." Suppose you had a ruler that reads in calories, you measure size of the fruit with it. Well, the distance measurements on that ruler can be accurate, but the calorie on that ruler are not. You can, however, use the ruler that reads in centimeters (or inches), with a conversion table, to obtain calories far more accurately.
Except that you can use your conversion table before you measure to ensure that your marks are accurate before you measure. If we didn't know what kind of fruit it was beforehand, that would be different.

I use the word reasonable here because every situation is different and must be looked at individually.

 Quote by pdObq You are contradicting yourself big time.
I'm going to revisit this, not because I'm so concerned that I might (be seen to) have contradicted myself, but because it's simply a false comparison.

Saying there's a "complex" of any kind does not mean everyone within this complex acts in unison, that it's a monolithic well-greased machine. The military industrial complex term appears to date to Eisenhower's speech:

http://en.wikipedia.org/wiki/Militar...strial_complex

and more recently other writers have added different societal sectors to the term, usually academic (google it and you'll find writings, at least on the web, about that factor), security, and political.

The intimate relations between the military and nuclear sectors go back to the begining of the nuclear age.

So, in sum, the MIC concept, at least, is well-established and supported by no small amount of evidence; adding other sectors less so, yet it's not something I just pulled out of my hat.

On the other hand, when one member of this forum states or strongly implies that two others think exactly alike based on a couple of statements by one of them (this statement about Dmytry and me was originally made after I'd made one or two posts) then they are being inaccurate.

So you have a bit of information being used arrive at an erroneous conclusion, vs. decades of information, books, the statements of a former POTUS/highest ranking general during WWII etc.

One would think this difference would be obvious.

I wrote:

So since you've stated that there isn't, in contradiction to many others (try the google, it's pretty cool), it's a fact. Right.

 Quote by Drakkith Not in the way you are referring to it there isn't.
And you're not responding to my point.

 Quote by Drakkith I've interacted with plentry of people as well. Most of them that DON'T have at least some small amount of scientific mindset don't have a clue how the world actually works. They tend to spew things such as "The government/big business/whatever they dont trust, is out to get them and everyone else and is evil or incompetent and can't ever be trusted at all".
So as long as the have a bit of scientific mindset they're not clueless. I'll agree somewhat, and would counter that people with ONLY a scientific mindset are equally clueless, except that such generalizations are not only full of contempt but also utterly simplistic and unrealistic.

 Quote by Drakkith Probably because of the difficulty in keeping tact for years of people who don't understand a word of what comes out of their mouths.
That kind of naivete has nothing to do with being unscientific. Moreover, the kind of utter disregard for those who don't share your mindset (sound familiar?) you're displaying here is destructive, but more interestingly exactly the kind of contemptuous/hubristic attitude that has being a major factor in getting us into deep doo-doo over and over (see Chernobyl, TMI, Macondo, FDI).

I'll go further and ask: how much death and destruction, how much pollution, how many babies and children blown apart by mines, cluster bombs, irradiated by DU munitions and exploding nuclear plants, etc etc etc has been caused by artists?

Poor performances, ugly, poorly-executed paintings, unlistenable music aside, just how much harm have these clueless artists wreaked on the world?

Now about that engendered by (99% well-meaning) scientists and engineers?

I'm not advocating a return to the stone-age. Technology is wonderful as long as it doesn't endanger our lives (or genetic heritage). But arrogant, contemtuous engineers who think, conversely, that the blueprints in the lab transfer perfectly to the messy reality outside have done much more harm to the world AND to the future of technology than any group of "clueless artistic-types."

 Quote by Drakkith Nonsense, if I make a statement that is 100% about something that is immune to opinion, such as facts, numbers, ETC, and I'm incorrect, then I will immediately admit my mistake when I am made aware of it. The problem here is that 99% of this thread ISN'T about those kinds of things.
First, you begin numerous responses to people with very disparaging words, the "nonsense" in this case being a perfect example.
Then, it's a huge assumption you're making that there's this clean, clear break between "facts, numbers" etc and how those facts and numbers affect the real world when applied to it.

Together, they create the exact impression of the one-sided, out-of-touch-with-reality, arrogant contemptuous scientist/engineer the very people you despise rail against.

 Quote by Drakkith It's about opinions. Even the title of the thread screams opinion.
And this is the whole point: you can't debate on this thread in such a black-and-white fashion while demonstrating such a lack of respect for those who disagree.

I've read your responses re technical aspects on this thread, and it's obvious you're well-schooled, but even then you're pretty caustic in refuting others.

Obtaining a BA/MA/PhD in literature (to take one example) means years of debating often absolutely debatable points--what did Shakespeare/Dickens/Joyce mean when he wrote this? One garners evidence the best one can and then makes a case with it--kind of like scientific research. But, as I stated before, many if not most people endeavoring in the humanities realize in the end it's all opinion--just better-supported or not-so-well supported opinion--so at least a modicum of self-doubt is not just helpful, but necessary to succeeding. The best scientists have this too, yet so many have this utter confidence in science as the sole source of the truth, which inexorably leads to dismissing non-scientists as clueless, as you have above.

Back in the day all students had to study a core curriculum of humanities, but with the increasing dominance of science and hi-tech in the world this has pretty much stopped. As a result most people in the tech-world these days have little or no education in the humanities. To me this is a monumental tragedy and is a factor in creating potentially monumental catastrophes like FDI.

You no doubt are of the opinion that I'm going way overboard. Well, this is an opinion thread, isn't it. If that's too messy for you perhaps you should stick to technical issues.

Your previous statement implies that all these complexes are all purposely doing harm to everyone, and then lying about it and spreading false information all on purpose. This ignores the fact that each of those complexes are made up of thousands of individuals whose ideals, beliefs, morals, etc are all diverse and range all over the place.

Knowing this, AND based on personal experience in some of these "complexes" myself, i guarantee you that your catchall statement is hideously incorrect. For every person that lies, cheats, and steals their way around there are dozens of honest people that work diligently and provide the best information possible.

I'm not disregarding anyone. You're the one continually bringing up pointless statements and judging entire groups of people.

As I don't know of any reliable way of finding out how many artists have been in the military, I can't tell you. But I'd bet there were a few.

 Poor performances, ugly, poorly-executed paintings, unlistenable music aside, just how much harm have these clueless artists wreaked on the world? Now about that engendered by (99% well-meaning) scientists and engineers?

How many poets, artists, songwriters, painters ETC have inspired rebellion, war, ETC in history? How many non scientists/engineers have made incorrect choices based on ignorance or dismissal? Or based purely on religious views? Plenty. EVERYONE is capable of making bad decisions or doing harm to someone else.

Have I linked any specific numbers? No. That's because I understand that no matter what I type up here on my computer, it won't be close to being accurate because I'm not there. I don't have the needed information.

 And this is the whole point: you can't debate on this thread in such a black-and-white fashion while demonstrating such a lack of respect for those who disagree.
Like you've been doing this whole time? I don't have any problem with your stance. Trust me, I'm not responding to you merely because you disagree with me. I'm attempting to point out WHY certain things work and others don't. And I will most definitively point out when people make assumptions about broad groups (like you have) for no good reason.

 I've read your responses re technical aspects on this thread, and it's obvious you're well-schooled, but even then you're pretty caustic in refuting others.

Sure. And if this was the case here I wouldn't have a problem. However this isn't the case. All I've seen is one person (including myself) after another spew random opinions about without any evidence to back any of it up. And on top of that, any evidence linked against that view is immediately disregarded as inaccurate because "people aren't trustworthy" or whatever. I try very hard to make sure that when I dispute something I do it for a reason and not merely because I don't believe it's accurate. Unless of course it's something only opinion based, and then I will try to explain why I believe their view is incorrect the best way I can.

 But, as I stated before, many if not most people endeavoring in the humanities realize in the end it's all opinion--just better-supported or not-so-well supported opinion--so at least a modicum of self-doubt is not just helpful, but necessary to succeeding.

Truth? What truth is there except science? Science at its base is a search for truth! It also includes things like humanities! How and why people act the way they do, different cultures, it all is encompassed. So I really don't know what you mean when you say that so many have this confidence as science as the sole source of truth, as I've never known anything else to be "truth".

I have no idea whether this is a factor or not. All I can say is that all in all safety is MUCH better nowadays than it has ever been.

That's fair. If this is going to be an "opinion thread" then I will post accordingly. I was unaware this thread was mostly opinion based.

Even if this could have done in far better conditions of course (i mean that we shouldn't wait for a tsunami and a nuclear crisis to do it of course, because these are tough conditions for citizens...) this crisis is probably going to lead to good measures to work on energy efficiency and energy saving programs:

Govt sets summer power-saving target at 15%

http://www3.nhk.or.jp/daily/english/13_18.html

 The plan that was hammered out on Friday by the government taskforce calls on corporate and individual users to reduce their electricity use by a uniform 15 percent from the peak summer period last year. This is ten percentage points lower than the maximum 25 percent target announced in April. Under the plan, factories and other major consumers will be asked to prepare to reduce their use of electricity in the summer.

Yes, this is a good thing. Everybody went on an energy conservation binge after the earthquake to minimize the need for blackouts, and it was pretty successful, but I think the big challenge this summer will be to see how well fans can replace air conditioners.

 Quote by jlduh If there should be an ultimate reason for not having privately owned companies running plants like the nuclear ones with so heavy consequences to social life and communities around in case of accidents, i think it could be this one: http://www3.nhk.or.jp/daily/english/10_20.html In the list of what they will do to raise "maximum" funding, I see "reduce the salaries and the bonuses -which bonuses by the way???? Will they still have bonuses???) BUT i DIDN'T see something like: "refund the necessary dividends accumulated in the past by shareholders" (for an other example of huge social impact of a crisis, this remark could apply to all private banks in the financial crisis, with in both cases the TOO BIG TO FAIL THREAT TO PUSH TO ACCEPT THE "DEAL") Instead of this, sates/citizens will probably pay collectively for it. For any "normal citizen", this is not acceptable to privatize the gains for years and share the losses with the community. Especially when a company has a so long list of frauds and lies to the community behind her... Ok, you drove drunk several times in the past, this time you have a huge accident and kill and injure many people and destroy their house, you have to pay fines and penalties for it and... you go to see the government to ask to help you to pay part of the stuff -but promise you will do your "maximum" to pay part of it! Does it sound right and logical to you, as a "normal citizen"? I know that it has been said several times here: "don't condemn them as long as you didn't run into their shoes". But hey, if I was a japanese citizen, couln't I say ALSO that they stealing MY SHOES in fact?
Gov decides about the structure to be put in place to help Tepco pay compensation:

http://www3.nhk.or.jp/daily/english/13_14.html

 Under the framework decided on Friday, a new state backed institution will be set up to facilitate quick payments to those affected. The new body would receive financial contributions from electric power companies that own nuclear power plants in Japan. The government will inject public funds by allocating to the institution a special type of bond that can be cashed whenever necessary.The institution would strengthen TEPCO's capital base by making use of these funds to pay compensation claims and make business investments. The institution would annually return a certain amount of money from TEPCO to the state coffers.
This is quite fuzzy to say the least. For sure Tepco has two big levers in its hands in case of bankrupcy: the risk of lack of supply AND the risk of leaving the state with 4 crippled reactors on its back. Would be interested to see what will be the final key ratio for financing this structure, between nuclear industry contributions and state contributions. Anyway, at the end, the ones who will pay are the citizens or the users (which are both the same). The only question is to know the contrinution of private nuclear shareholders in the compensation financing.

Why doesn't nuclear industry have a mutual compensation system (mutual insurance) being feed by nuclear companies, to be used in that kind of accident? Even if it proved not sufficent, oil industry have something like that in place i think. It can also be done with a kind of reinsurance mutual fund, like ASSURPOL in France (even if i think the nuclear industry is not in this system either in France: nuclear risks are so big that the insurance for consequences is a real problem, but one way or the other, this has to be adressed -and its better if it is before hand!- and costs to be included in the total cost of the produced energy through nuclear plants):

http://www.assurpol.fr/index.php?page=general

This news confirms go into the direction of 2 points already mentionned in this thread, the latter being just above:

http://www3.nhk.or.jp/daily/english/13_20.html

 Referring to information offered by Japan right after the accident, Poneman said the US side had difficulty grasping what was actually happening. He said if US officials had been able to obtain data more quickly, they could have given better advice.
It seems that not only us here are saying this...

 Poneman said that even before the Fukushima crisis, the US had repeatedly urged Japan to ratify an international treaty over damage from serious nuclear plant accidents. He expressed hope that Japan will ratify the pact soon. Under the treaty, compensation for serious nuclear accidents would be financially supported by funds collected from the signatories.
Well, this is precisely what i was mentionning in the post above!

Some more contamination of tea leaves:

http://www3.nhk.or.jp/daily/english/13_39.html

 Radioactive material above designated safety limits has been detected in tea leaves harvested in 5 municipalities in Kanagawa Prefecture, neighboring Tokyo. The prefectural government checked samples of leaves harvested in 15 municipalities in the region. Officials say that samples from 5 of those were found to contain unsafe levels of radioactive cesium. They say 780 becquerels of cesium were detected in tea leaves in Odawara City, 740 becquerels in Kiyokawa Village, 680 becquerels in Yugawara Town, 670 becquerels in Aikawa Town and 530 becquerels in Manazuru Town.
Damn, this info is really a breaking news to me, not because of the levels (even it there are sufficiently high to make them unsafe!) but BECAUSE OF WHERE THEY HAVE BEEN MEASURED:

KANAGAWA prefecture is south of Tokyo!!!!

I located Odawara on this map for example:
