  • @Dennis Tucker Jr It says that they analysed for all isotopes in the table, but that some did not amount to the "detection value".

  • @George That NYT article makes a good point, about these plant designs being based on old science. Given the aging infrastructure and lack of any sort of disposal strategy, isn't that true of most of our plants?

  • @KT39 0,3 mBq/m3 was measured as far away as Stockholm (Sweden) four days ago.

  • @kb which would make sense, since I134 has a half life of only 52 minutes
    by marie rich 3/27/2011 5:43:18 PM

  • @kb 0.3 mBq/m3 sounds like pretty much nothing though.. About one decay per hour per cubic meter - amazed it's even possible to distinguish that from the general background radiation.

  • @radioguy: every country thinks their engineers are the most competent and that their regulatory agency will effectively enforce the regulations....i read somewhere that these old reactors are like atm's for their respective energy company's.

  • I think I have identified the SFP of No. 3 from a correlation of videos. imgur.com Flight at the 15th i.imgur.com Flight at the 27th We can't be totally sure about this, but I think the location of the destroyed crane and the cement pump at #4 (south side) is a another good indication.

  • @Dennis Tucker: your opinion please. I've followed this site from the beginning of this EVENT. This morning I noticed Dean posted it as well. Zero Hedge - Following the eariler TEMPCO flap, here is a simple way to resolve the true radioactivity at reactor 2 - "All that needs to be disclosed now is how long these workers were in the contaminated water for. If it was between 2 and 6 hours, and the cumulative exposure was 2 - 6 sieverts, it would be rather consistent with the reported record exposure of 1 sievert/hour. If it was shorter, and the upper estimate is correct, the exposure could be as high as 6 sieverts/hour, a figure, based on the prior methodology, about 60 million times higher than permitted". www.zerohedge.com

  • One of the articles I've read said the workers were in the water for 40 minutes.
    by Miles 3/27/2011 5:49:58 PM

  • @all remember that sieverts are "absorbed dose" if we are talking about wounds on the legs and water getting into the wounds, even a lower dose of environmental radiation will cause a higher dose of absorbed radiation. Internal radiation can increase sieverts by 1000x fold.

  • In one of the other pics of the maintenance process it showed it swung off to the side and hanging there.
    by radioguy 3/27/2011 5:52:59 PM

  • @Nancy : yes, but they can't impossibly leave it hanging on a crane for a long period. in case of an earthquake this is completely unstable !

  • @All - I am not a subscriber so not sure there are many pertinent details in that article.

  • TEPCO says the radioactive materials include 2.9-billion (not million, is this the error that led to the 10 million figure?) becquerels of iodine-134, 13-million becquerels of iodine-131, and 2.3-million becquerels each for cesium 134 and 137.

    by Matsuoko 3/27/2011 5:55:35 PM

  • @ralph please also keep in mind iodine 134 breaks down in a matter of hours. I believe they took the same sample hours later and retested it. Showing far lower levels because of the short half-life nuclides breaking down.
    by Patrick Kelley 3/27/2011 5:55:48 PM

  • I have followed zero hedge for a few years now and they are known to tell it like it is. Their coverage of the financial crisis has been very good.
    by George Gibb 3/27/2011 5:55:56 PM

  • @Matsuko OK, so they must have replaced the cap after the maintenance? I can't believe they'd either leave it hanging OR put it somewhere else but on the reactor.
    by radioguy 3/27/2011 5:57:04 PM

  • also, based on the amount of radiation in this pool, I doubt they sent someone in to get a new sample. Using a 5 hour old sample to test for isotopes that only last 1-2hr's of course the results will be much, much lower.
    by Patrick Kelley 3/27/2011 5:57:54 PM

  • @Patrick Kelly Yes. Iodine134 has a half life of 52minutes. So enough could have broken down tto not be a significant measurement.

  • [OPINION] An example of how the Japanese government manages extreme crisis can be found in their response to the economic "Bubble" catastrophe of the 1990s. Japan was on top of the world back then when suddenly their economy exploded, property values plummeted and the Nikkei went from 38.9K to below 10K. The Japanese opted for a slow, incremental approach to resolving the problem, an approach that is still in operation decades later. Contrast this with the US approach to the Savings & Loan crisis of the 80s or the much more recent economic crisis of 2008 --Extraordinary stimulus and clean up activities. I do not personally feel that slow, incremental steps will resolve the Fukushima crisis in an optimal manner. I hope that despite evidence to the contrary, the Japanese authorities are aggressively engaged & not quietly preparing themselves for a 30 year program of timid counter-measures.

  • @Patrick If that's so, they would have had to know it was bad science when they released that info.

  • Tepco Chief Pressured to Quit After Costing Holders $26 Billion - www.businessweek.com I think it's going to be a lot more than 26 billion...
    by Miles 3/27/2011 5:58:40 PM

  • @radioguy : i do not know that, but it seems logical, no ? having a huge cap hanging on a crane during an earthquake does not really make sense. this seems criminal to me.
    by Matsuoko 3/27/2011 5:58:58 PM

  • @radioguy, obviously.
    by Patrick Kelley 3/27/2011 5:59:19 PM

  • @matsucko would make sense it was put thier during refuling work, to blow off would have to have been internal pressure in my opion and would have caused serious "ripping" efect damage.. the quake happened during work hours and here in the states, maintaince work can run 24/7 so as to get unit back on line.. do not know the paticulars of what they were doing to unit #4 that it was already in shut down mode
    by fitter 3/27/2011 5:59:43 PM

  • @Miles @Tenzing Thanks. I have read the same article Tenzing have read. What is strange also is that the video we have all seen whas showing lesion on an arm ... When exposed to such radioactivity, even if it is by the feets, all the body show problems, I don't think 1000 millisiverts have show these wounds "one day after" , and if we look at Chernobyl last footage, the only one who seem to have the same wounding were people exposed to several dozen Siverts or sometime hundreds. [opinion]
    by Future Isnow 3/27/2011 6:00:14 PM

  • If Tepco is like US nuke co. they have a liability cap, that may be the 26 billion figure.
    by Ralph Unger 3/27/2011 6:00:16 PM

  • @Miles idk. GoJ is already saying they will cover costs of tsunami repairs for all people in affected areas. TEPCO might be "too big to fail" *GAG*
    by marie rich 3/27/2011 6:00:29 PM

  • @Future et all Do we know the reactor lid was still off after an operation started in December? Wouldn't that expose the area around it to some constant residual radiation?
    by radioguy 3/27/2011 6:01:34 PM

  • @Miles Yep...the TEPCO chief is going to be the first guy thrown under the bus for the Fukushima disaster. I knew that was going to happen when he apologized publicly a few days ago.
    by James Ward 3/27/2011 6:02:09 PM

  • @marie rich the problem with the so called to big to fail status is the tax payers are now starting to understand they are to big to support
    by George Gibb 3/27/2011 6:02:55 PM

  • Well, they announced that TEPCO will be liable for damages etc. There is no way they'll be able to pay that, so guess shareholders will get wiped out and the rest nationalised/guaranteed by the state and later re-privatised or some such.
    by sims 3/27/2011 6:03:27 PM

  • @Miles to be honest, the future of Masataka Shimizu, I don't give a dimme. the only concern for me is that investores still play for the up or down of the shares. And that is something I can't understand , in such a crisis. Tepco cotation should have been stopped the 12 march... Just a thought : what is Tepco declare bankrupcy tomorrow morning, and sent home all his workers ???
