  • @ ariadne, your point on the 40 years old is good, what it could mean would have been a decision to use the pills or other form for people under 40 years old in order to make the pills last longer
    by dean 8/11/2011 3:48:53 PM

  • Anyone have any major changes for the article?
    by lillymunster 8/11/2011 3:49:29 PM

  • @dean even then, 4 days is still not enough.
    by Edano 8/11/2011 3:49:51 PM

  • @ lilly, it's good with the comments made
    by dean 8/11/2011 3:51:17 PM

  • true @ Edano, ongoing surveys for iodine would have to have been performed for the population to know they needed to continue..
    by dean 8/11/2011 3:52:51 PM

  • we have to conclude, consequent evacuation is the best for the people. they understood that in chernobyl, but now they followed the recommendations of the criminals in iaea and icrp and now they have a mess. the preparations for disasters failed completely (speedi, potassium).
    by Edano 8/11/2011 3:54:40 PM

  • @Edano, whats the chance they will pick things up and help the people who have been exposed
    by dean 8/11/2011 3:57:19 PM

  • @dean yes they need regular checks and they need to be evacuated if they had exposure in order to minimize more exposure.
    by Edano 8/11/2011 3:58:19 PM

  • @Edano BS.. Evacuation means great psychological disruption, we go from a SMALL increased risk, to a unidentifiable risk.
    by RBeaner 8/11/2011 3:58:51 PM

  • Dean, that seems to be the added anxiety of people in Japan. Many know they were exposed to some extent or that their community also has radiation. They have seen the govt. actions to date and have lots of worry about what will happen in the future, or not happen.
    by lillymunster 8/11/2011 3:58:55 PM

  • @dean for fuku it is too late, but we have to put pressure on our govmts to revise disaster plans.
    by Edano 8/11/2011 3:59:30 PM

  • @lilly, I could not find out yet how GoJ measured these doses. The device with the chair that edano posted earlier can be used for organ counts. It is not a whole body counter, and you do not need the fancy shielded chair as long as the room is shielded. Basements in hospitals usually are good places. A whole body count is only needed to determine internal whole body contamination and not necessary for thyroid counts.
    by Peter Melzer 8/11/2011 3:59:39 PM

  • There is also a considerable daily anxiety of living in a known or assumed contaminated area. Everything in life becomes a stressful event, eating, going outside, rain. etc.
    by lillymunster 8/11/2011 3:59:44 PM

  • @Peter Melzer I saw a picture of someone using a hand held device similar to the one in Edano's picture but wasn't 100% sure of the location and date
    by lillymunster 8/11/2011 4:00:31 PM

  • The Japanese govt would also need to deal with the panic factor if they started giving potassium iodide to people in the impacted area. In the SF area there were a number of news articles about people who could not buy it in local pharmacies. For example "Profiteering From A Panic: The $1,740 Potassium Iodide Supply" www.reportingonhealth.org
    by RonD 8/11/2011 4:00:54 PM

  • @Peter Melzer but you can use the whole body counter for thyroid only, too.
    by Edano 8/11/2011 4:03:37 PM

  • by Edano via Www2.fz-juelich.de 8/11/2011 4:04:50 PM

  • @lillymunster , you can do spot checks like that, like you hold the Geiger to the neck and if someone has got a good load you will notice right away. But for accurate dose assessment, you need counts in a calibrated environment. Any nuclear medicine department in a hospital can do this with a detector depicted in edano's post (in Germany apparently for fifty bucks). The trick is the instrument must be calibrated to give you the proper dose estimates and the techs must adhere to a specific measurement geometry.

  • will return in awhile.. ty all excellent time
    by dean 8/11/2011 4:06:17 PM

  • by Edano via Klinikum.uni-muenster.de 8/11/2011 4:06:18 PM

  • @Edano , you could, but they are not as widely available as the other instruments.
    by Peter Melzer 8/11/2011 4:06:47 PM

  • @Edano as I remember they used a handheld device for the thyroid tested children they put photo in the media didn't they?
    by elainekirk 8/11/2011 4:06:52 PM

  • @elainekirk i don't remember. i think the handhelds are only for external exposures (on the cloths, e.g.).
    by Edano 8/11/2011 4:08:06 PM

  • @you i agree to peter. you need a calibrated environment. no handhelds.
    by Edano 8/11/2011 4:09:12 PM

  • @Edano ah I will be confusing with the evacs where they waved their magic wand over everyone
    by elainekirk 8/11/2011 4:09:16 PM

  • @lillymunster I saw you mentioned article further down is it done?
    by elainekirk 8/11/2011 4:09:50 PM

  • @elainekirk yes just posted.
    by lillymunster 8/11/2011 4:11:32 PM

  • @elaine, as I said for rough checks handhelds are fine. But I cannot believe that GoJ used those to derive the doses for the children. That would be wrought with error.
    by Peter Melzer 8/11/2011 4:12:48 PM

  • @lillymunster I will go see ty @Peter no they did proper tests on x number then extrop.... I was confusing readers because I dont know much about them :)

  • RE: Rbeaner's post below, extrapolation: The Chernobyl reactor accident resulted in massive releases of 131I and other radioiodines.
    Beginning approximately 4 years after the accident, a sharp increase in the incidence of thyroid
    cancer among children and adolescents in Belarus and Ukraine (areas covered by the radioactive
    plume) was observed. In some regions, for the first 4 years of this striking increase, observed
    cases of thyroid cancer among children aged 0 through 4 years at the time of the accident
    exceeded expected number of cases by 30- to 60-fold. During the ensuing years, in the most
    heavily affected areas, incidence is as much as 100-fold compared to pre-Chernobyl rates
    (Robbins and Schneider 2000; Gavrilin et al., 1999; Likhtarev et al., 1993; Zvonova and Balonov
    1993). The majority of cases occurred in children who apparently received less than 30 cGy to
    the thyroid (Astakhova et al., 1998).....We have concluded that the best dose-response information from Chernobyl
    shows a marked increase in risk of thyroid cancer in children with exposures of 5 cGy or greater
    (Astakhova et. al., 1998; Ivanov et al., 1999; Kazakov et al., 1992)....It is also notable that the thyroid radiation exposures after Chernobyl were virtually all internal,
    from radioiodines. 1 For the radiation emitted by 131 I (electrons and photons), the radiation-weighting factor is equal to one, so that the
    absorbed dose to the thyroid gland expressed in centigrays (cGy) is numerically equal to the thyroid equivalent dose
    expressed in rem (1 cGy = 1 rem). [50mSv = 50rem] www.fda.gov

  • @elainekirk yes
    by lillymunster 8/11/2011 4:28:16 PM

  • @lillymunster done @peter I worked out from the number of pills gov say they distributed and the number of people in nuke evac centres that they only had a few days supply , the figure of doses looked big till you shared them out

    TEPCO radiation measurement training
    Employees of Tokyo Electric Power Co. take part in a radiation measurement training session at the J-Village athletic training facility in Fukushima Prefecture on Aug. 6, 2011. TEPCO, the operator of the crippled Fukushima Daiichi power plant, has been conducting the training sessions since May 30. (Photo courtesy of TEPCO)(Kyodo) english.kyodonews.jp

    by Edano via English.kyodonews.jp 8/11/2011 4:34:52 PM

  • So according to the FDA, the chld who received a 35mSv absorbed dose has a 60 to 100 fold increased chance of thyroid cancer? And even 5 rem (5mSv) absorbed dose can cause a marked increase in risk?!
    by M.I.A. 8/11/2011 4:36:20 PM

  • @Edano , that approach is what I figured.
    by Peter Melzer 8/11/2011 4:36:35 PM

  • @Edano Oh book a duck they are joking !!!! to tepco training = leaving them to get on with it

  • @elainekirk , as law-abiding as Japanese citizens are, I smell that very few took them. It would be interesting to find some of those instructions the municipal govs were supposed to disseminate.
    by Peter Melzer 8/11/2011 4:41:55 PM

  • TEPCO is in pointless PR mode again. Either they got in trouble with an agency or they are preparing to drop another "bomb" of ba
