Fukushima Decontamination Cost Estimated $50bn, With Questionable Effectiveness

AmiMoJo writes "Experts from the National Institute of Advanced Industrial Science and Technology studied the cost of decontamination for the Fukushima Daiichi nuclear accident, estimating it at $50 billion. They estimate that decontamination in no-entry zones will cost up to 20 billion dollars, and in other areas, 31 billion dollars. It includes the cost of removing, transporting and storing radioactive waste such as contaminated soil. The central government has so far allocated about 11 billion dollars and the project is already substantially behind schedule. Meanwhile the effectiveness of the decontamination is being questioned. NHK compared data from before and after decontamination at 43 districts in 21 municipalities across Fukushima Prefecture. In 33 of the districts, or 77 percent of the total, radiation levels were still higher than the government-set standard of one millisievert per year. In areas near the Fukushima Daiichi nuclear plant, where decontamination has been carried out on an experimental basis, radiation levels remain 10 to 60 times higher than the official limit."

      The half-life of some of the radioisotopes in the cleaned area around Fukushima is measured in decades, indeed. Yet the concentration of those radioisotopes around you is so low that they are giving you only 1 mSv per year. (Or so says by jkflying. I haven't checked if that number is accurate, but that's not my point.)

      Let me give you two examples to help you understand how this really works, since it has become evident that ironically you don't (not that there's any shame in not knowing about some very specific topics like this). I will break it down into three comments for readability. For the examples, let's use F-18 and Na-22 since they are both positron emittors, so the potential damage due to each decay is similar. (It's actually caused either by the removal of a critical electron when it is annihilated by the positron or by the two 511 keV photons produced that mutual annihilation.) That's easier than trying to compare radioisotopes with different products. From the POV of radiation poisoning, the difference is the half-lives: 109.8 min for F-18, 2.6 years for Na-22.

      In the paper I linked before they used a very typical dose of 10 mCi or 370 MBq of FDG, that is 370 million decays of F-18 isotopes per second at the time of injection. That means that 3.52 x 10^12 atoms (5.84 x 10^-12 moles) of F-18 are injected, all of which decay inside his body... well, not really as he will urinate some of them, but the same can be said of most any collection of radioisotopes you ingest: a portion of what you ingest will remain in certain tissues and a portion will be excreted. So let's assume he doesn't pee for 10 hours and that the F-18 remaining in his body after he peed magically disappears: then the number isotopes that did decay in his body is 3.44 x 10^12 (5.71 x 10^-12 moles). Since there is one F-18 isotope per FDG molecule that amounts to 1.04 x 10^-9 g of pure FDG that decays, from a starting amount of 1.06x10^-9 g. If you follow the numbers, be it isotopes, moles, or grams of FDG, you will notice that 97.7% of the F-18 decayed inside the patient and only 2.3% did not.

    15. Re:Huge waste of money by Smurf · · Score: 1

      Second example: If we want to replicate the health effects of the F-18 in the FDG using Na-22, how much Na-22 do we need? To get the 370 MBq at the start you will need 4.38 x 10^16 atoms of Na-22 (1.6 x 10^6 g), obviously still a minuscule amount. So let's push your concept of "long half-lives are what matters" to the extreme and use instead K-40, a positron emitter with a half-life of 1.248 x 10^9 years. To replicate the effect of the F-18 you need to start with a chunk of potassium that has 2.10 x 10^25 atoms, all of them radioactive! That's 34.9 moles or 1400 grams of potassium... that's 3 pounds of pure, wholly radioactive potassium circulating around your body!

      Of course that radioactive potassium is disappearing "magically" at an accelerated rate (a very small part due to radioactive decay and a lot more that we need to remove continuously to match the effects of the F-18 in the FDG). Yet after 10 hours, the time at which we assumed that the patient excreted all the remaining F-18, he will still have 31.6 g (more than one ounce) of 100% radioactive potassium circulating through his body. So the effects of the radioactive FDG for the patient are comparable to having circulating inside his body between one ounce and 3 pounds of a 100% radioactive metal for 10 full hours!

      The big lesson here is: The effects of the half-life of a radioisotope on a person exposed to it are not as intuitive as you think. You made the rookie mistake of dismissing the effects of 370 MBq of FDG just because the half-life is short.

      So why do people care more about the Cs-137 (half-life: 30.17 years) than about the I-131 (half-life: 8 days)? It is NOT as you think because one million atoms of Cs-137 are more dangerous than one million atoms of I-131 if they get into your body. (Arguably the iodine is far more dangerous as it is avidly uptaken by the thyroid gland). It's because 29 years from now half a million of the Cs-137 atoms will still be there waiting to get into you, while the I-131 pretty much vanished five months after the accident.

      TL; DR: the 6.23 mSv dose due to the FDG PET scan in my original comment are comprable to more than 6.23 times the 1 mSv dose that a person would be exposed to in a year in the "cleaned" areas of Fukushima for two reasons:
      First: because it's already inside his body instead of just potentially (as I said before), and
      Second: precisely because the half-life of F-18 is very short.

      BTW, your extremely condescending attitude is a personal attack, particularly when accompanied by no enlightening knowledge which would at least support your position or (preferably) allow me to improve my own knowledge of the topic. Please don't pretend to be so stupid that you can't recognise this. There is a difference between blindly putting somebody down by telling them they are juvenile and wrong, and trying to teach them through relevant information that they are incorrect. The first is a personal attack, the latter is civilised discourse.

      Pointing out foolishness and silly game playing should not be mistaken for being condescending. Your cut and paste attempt to "educate" me in the post directly above however is of course very condescending. I am not going to pretend to be so stupid as to confuse that with a personal attack. I'd rather you didn't either since you cannot possibly be as stupid as you pretend. Do you get it from the style of a cocaine ravaged ex-DJ on TV? He has an excuse of a damaged brain and it's meant to be entertainment and not a serious discussion anyway. Please don't bring these tactics meant for entertainment into what is supposed to be a discussion and not a debate. Tactics, especially underhanded ones, are not necessary and in fact just a pointless waste of time. I can't even bring myself to laugh at the pathetic character you are pretending to be let alone get entertainment out of it.

      this still makes the 'contaminated' areas have lower radiation exposure than somewhere like Denver

      Here is what I posted in the "above" I referenced in my first reply to you: http://isis-online.org/risk/tab7
      Effective annual radiation due to natural sources in Denver is 11.8 mSv/y

      So, let's look at the summary of the article that we're posting on:

      In 33 of the districts, or 77 percent of the total, radiation levels were still higher than the government-set standard of one millisievert per year. In areas near the Fukushima Daiichi nuclear plant, where decontamination has been carried out on an experimental basis, radiation levels remain 10 to 60 times higher than the official limit.

      So, the self-imposed government standard Japan has used to decide whether the areas are safe to inhabit is 1 mSv/y, and 23% of the Fukishima Prefecture are below this, that is 10x lower than Denver. Of the experimentally decontaminated areas near to the plant, they are 10x - 60x higher than the government standard, so anywhere from equal to Denver to 6x what Denver has.

      To put this into perspective, this "government standard" they have imposed is actually lower than the average background radiation in Japan (1.4 mSv/y), and less than 1/3 of the average background radiation in the USA (3.1 mSv/y). I don't think they are likely to get massive areas of their land lower than average, just by the laws of statistics, which makes me think the politicians are just fearmongering by setting such a low standard.

      So, I've put my numbers and sources down. As I've said, I'm not a fanboy. There was contamination, sure, I'm not denying that. What I'm saying is that the amount, after some decontamination efforts, is small enough that in the big picture, given the amount of energy generated by the plant, it is negligible compared to emissions from coal or chemicals produced during solar panel production. I think nuclear is one of the safest power generation methods we have. We just need to move away from 70s technology and not do stupid things like build them where tsunamis and earthquakes can do a double-wammy, without sufficient safety mechanisms to handle that.

You've shown you are a liar so why should I believe your current post anyway?
    This sort of shit defending badly run 1970s plants with adhoc onsite waste storage is the sort of stupid shit that is holding back the advance of civilian nuclear technology. You raving fanboys seem to think perfection happened years ago so there is not point actually trying to improve the technology. It's the sort of shit that killed the thorium project.

      I never said the contaminated areas are less than Denver, please don't put words in my mouth. I said the 'contaminated' areas are less than Denver. Big difference. Those single quotes mean I was referring to stuff which wasn't actually contaminated.

      Obviously the area directly around the reactor is contaminated. Obviously. It blew up, and it contained radioactive material when it did. That material had to go somewhere, and it (mostly) ended up directly around the reactor. If you thought I was referring to this when I said "10x less than Denver", I wasn't. A miscommunication, misunderstanding, whatever.

      But the 'contaminated' areas, the greater surrounding areas which were evacuated, the farmlands, the fields, the houses, the shops, are perfectly habitable, perfectly safe, and yes, 10x less radiation than Denver. That area is a lot bigger than the actual next-to-the-reactor contaminated area. Orders-of-magnitude kind of bigger. Big enough to make the actual contaminated area look pretty irrelevant in the greater scheme of things.

      And I think you missed when I said:

      We just need to move away from 70s technology and not do stupid things like build them where tsunamis and earthquakes can do a double-wammy, without sufficient safety mechanisms to handle that.

      So you see, as far as I can tell, we agree on this. In fact, I believe you'll find my position has been entirely consistent once you read what I actually said. No goalpost shifting. No bait-and-switch. No rabid fanboyism.

      All I'm trying to point out is that the actual contamination (no quotes this time) was significantly less, in both area and intensity, than people seem to believe. Even in the bad areas, the ones directly around the reactor, decontamination efforts can make them safe again. Safe to within 6x what is experienced at Denver from 100% natural causes, even after you normalise for the different types of radiation and how it affects the human body.
