  • @all, here are some pics of ground zero here in Hiroshima. The first pic is of the dome and sakura (taken last year) the other pics were all taken today on my bike ride to work. Ground zero is a few blocks behind the dome on a side street and is only marked with a small brown marker. All of the sites related to the bombing use these brown markers. In Nagasaki, ground zero is the center of the park, but here most people come to Hiroshima and never find ground zero. Very strange. A colleague of mine always likes to go for a drink at the bar closest to ground zero. gallery.me.com

  • U.S. doctors hit Tokyo radiation limit for kids search.japantimes.co.jp ""(Twenty millisieverts) for children exposes them to a 1 in 200 risk of getting cancer. And if they are exposed to this dose for two years, the risk is 1 in 100. There is no way that this level of exposure can be considered 'safe' for children," the statement said."

  • back for a bit...@dean "in my nuclear world we call that a leaker." I was surprised in my post 3/11 research| to learn how much more there is beyond Chernobyl and TMI... Is your reactor an AGN or.. No Rob

    @Markfm "Cherenkov radiation is not low level stuff, it's a high power event."
    Yeah, but... See "spent" fuel assy. above.

  • Second woman over legally set limit search.japantimes.co.jp "Meanwhile, two workers who were laying cable at the plant who were briefly hospitalized for alpha ray burns after stepping into puddles of highly radioactive water that no one warned them about, were revealed Saturday to have absorbed nearly 250 millisieverts of radiation." (The quote is, I believe, about the workers who stepped in the puddle that supposedly wasn't there the day before.)

  • @Markfm Raising the "safe" levels is fracking criminal. Makes me sick that any human could be so callous and have so little regard for any life besides their own.

  • typically. at nuclear plants they have sewer which can go to a treatment facility for processing.. and it sounds like in japan they have sludge from that which is assumed clean however, if there were damage to the sewer system where plant water that was contaminated ended up in the sewage. .it would show up in the treatment facility.... the other kinda of water.. would be clean water drains, low level liguid waste that can be treated and then be clean.. and higher level waste that has to be either sent to a pond to evaporate.. or to some other facility
    by dean 5/2/2011 2:23:23 PM

  • @dean I thought the Hot sludge came from Ibraki?prefecture, but as with most, can't relocate the link that had specific info.

  • my comment earlier about the fuel element leakers.. typically in my world if youo have a leaker you shut down .. take all the fuel out and replace it.. .. they could do the same in commercial reactors..

  • @dean @RB two different senerios.... RB i have been working on equipment (the SPF have a very complex cleaning system (think it also ties into the reator water) it has its own sludge tank and the pipe cleaning system is also involded... the "sludge in the waste treatment plants in the recent articles is different than what I have been looking to clairify.... but appreciate the help...

  • @dean The sludge at a treatment centre in Koriyama City, Fukushima Prefecture, had 26,400 becquerels of radioactive caesium per kilogram, Jiji Press reported citing local government officials, dpa reported.

    At the centre located some 50 kilometres west of the stricken Fukushima Daiichi nuclear power plant, slag made by reducing the volume of sewage sludge had 334,000 becquerels per kilogram, Jiji said. en.trend.az

  • fitter.. that's why I wanted to talk to you about the sludge at nuk plants..
    by dean 5/2/2011 2:34:54 PM

  • to break down where it comes from and then what is done with each source
    by dean 5/2/2011 2:35:09 PM

  • Gotta break off for some rest. Thanks, all. Great chatter this morning (my night at GMT+8). Cheers.

  • @Markfm We were discussing that this past weekend. The puddle he stepped in was measured at 2-6 Sieverts, and the 240.8 mSv or whatever they're quoting has not been clarified as to how measured. Dean has stressed that any testing MUST be full body.
    AFAIK, we as yet we have no indication that these figures are such.
    by Rob in SF 5/2/2011 2:37:00 PM

  • @RBeaner I was just refering to the recent article to show that sludge can become "hot" I have been trying to figure out how HOT and does it start having half lifes.... on the #1 bld you have equip#1207-10 reciver tank and 1207-9 sludge system pump... the lines come through what appear to be a "hot" pipe chase ,, (assume) from the SFP...

  • Sorry tried to post pic changed link to plixi photo below
    by elainekirk 5/2/2011 2:38:18 PM

  • as RB would know.. there are limits to whole body dose which is generally used. but there are also limits to extremities that are different .. so the man stepping in the water would have to have whole body as well as extremity dose
    by dean 5/2/2011 2:38:20 PM

  • fitter.. we should talk on that..
    by dean 5/2/2011 2:39:38 PM

  • From the weekend JAIF EQ report "The utility says it took about one month to measure their internal exposure levels." It doesn't describe how the numbers were attained, just that it took significant time to come up with the estimate.
    by Markfm edited by Markfm 5/2/2011 2:43:19 PM

  • @dean I have to get some work done on my pipe chasing and read up more on the cleaning/deminerlize water systems... but from what i have looked at quickly the whole systems tie to gether and are intergral to maintaining the pool water and the reactor water... the sludge would be the particals left from the filtering process

    Yo Bo. What's the going rate for a hotel room in Hiroshima?
    by Rob in SF 5/2/2011 2:45:50 PM

  • @Markfm If it took that long to determine their dose, than it truly is a wonder that they both 'happened' to have sustained *just* under the 'legal' limit for exposure. What a coincidence... *rolls eyes*
    by Askwhy 5/2/2011 2:46:04 PM

  • @Rob is SF very affordable. Hotels in Japan are very affordable. You can get a room for as low as $60, and a nice room (although small) for under $100
    by bo 5/2/2011 2:48:05 PM

  • ok fitter
    by dean 5/2/2011 2:48:52 PM

  • @Askwhy Easy look at how dose is assessed and controlled within extremity vs wholebody dose. www.jlab.org Internal dose will be computed based on chest count/whole body assay.
    by RBeaner 5/2/2011 2:50:05 PM

  • @bo I've got too many miles, no current job, and several HD cameras with rigs...
    by Rob in SF 5/2/2011 2:50:14 PM

  • RB are you surprised that they don't have whole body counters more readily available.. and do you think the japanese use different guidlines that what we're used to ?
    by dean 5/2/2011 2:51:02 PM

  • FITTER are you there.. .
    by dean 5/2/2011 2:52:31 PM

  • @Rob in SF then you should come for sure. Hiroshima is a fascinating town. There are also wonderful ancient sites near by too, my favorite temple in all of Japan is on the hill where I live and it just celebrated its 1300 anniversary. I'd be honored to show you around and buy you a drink in the bar closest to ground zero
    by bo 5/2/2011 2:52:49 PM

  • @RBeaner What I mean is, if they had the sense to pull the workers at the time of the exposure (because it was clearly dangerous enough to do so), but had no idea at the time of exactly how much radiation they had received, it seems downright miraculous that the moment they chose to pull the worked just 'happened' to be within 20mSv of the legal limit, but still below it.
