  • @Pedro Jesus , the gases have gone and decayed. Gamma radiation intensity will diminish following the inverse square law, that is with the square of the distance from the source. The beta radiation should be absorbed by the pipe metal.

  • 8 radiation sickness signs Due to nuclear assaults on the environment and life on it, humans are increasingly susceptible to irradiation poisoning them. Little information is being broadcasted about radiation sickness and its eight main signs. People who have been radiated often, therefore, attribute their new conditions to other than the actual cause, radiation. www.examiner.com

  • @Peter Melzer here they speak of >200 people with acute radiation syndrome ! www.focus.de
    by Edano 8/2/2011 4:34:47 PM

  • @Peter Melzer Most people here do not "believe" in the inverse square law, or the plane or line source law. They really don't believe radiation decreases with distance from the source.

  • @Edano This is the best article a read in a long time.
    by Majj 8/2/2011 4:37:30 PM

  • @Majj : yes, i also liked it.
    by Edano 8/2/2011 4:38:19 PM

  • @RBeaner , we were talking about a point gamma-source in the stack. You can verify the validity of this law with a point source in any lab.

  • @Edano , wonder where they got this idea from. As any disease, acute radiation syndrome is diagnosed along indicators that must be confirmed, among which are leukocytopenia and thrombocytopenia. You would need access to people's medical records to affirm this claim. If true, it would be horrible.

  • @Edano So everything inside the outer line of his arm, then almost striaght down from his hand to just below his hip then up to his other hand and back below the blue logo is blurred, possibly completely replaced. WHay?
    by RadioGuy 8/2/2011 4:49:04 PM

  • @Peter Melzer yes, it's scary. but who knows the dimensions of the cover-ups ?
    by Edano 8/2/2011 4:50:44 PM

  • @RadioGuy : because in reality he was just peeing.
    by Edano 8/2/2011 4:51:15 PM

  • @Edano Well, we know they tried their damnedest to hide three meltdown/melt-throughs. I guess that's your baseline.
    by RadioGuy 8/2/2011 4:51:51 PM

  • @Edano heh
    by RadioGuy 8/2/2011 4:51:57 PM

  • So the one useful thing I gleaned from that Cesium solubility paper is that the more ammonia there is in the CS-HNO3-H2) solution, the more Cs-137 is soluble in teh evaporate. Adding all that nitrogen seems a terrible idea, then.

  • @RadioGuy i am not a photographer, but i have often seen blurred schemes around a very bright object (think of christmas tree candles, i know, you don't have them in the US :)).
    by Edano 8/2/2011 4:56:00 PM

  • or he is already a "walking ghost" => en.wikipedia.org
    by Edano 8/2/2011 4:58:34 PM

  • I'm old enough to have seen them. ;) Anyway, I can't think of anything that blurring could have been designed to hide except that they lied about the detector having only a 10Sv/hr range, or even about the guy being there, but that's a very small lie by TEPCO standards so it's just another one of those little mysteries that surround this.
    by RadioGuy 8/2/2011 4:59:00 PM

  • @Edano , the discovery of such thing would be a game changer for sure. I can't recall, but I thought that hardly anyone diagnosed with ARS after the Chernobyl disaster survived.

  • "The prognosis is usually terminal. Given that there is no possibility of recovery, all current medical treatments are palliative, e.g., pain management using morphine and similarly powerful analgesic drugs."
    by Edano 8/2/2011 5:04:09 PM

  • So when they're talking about radiation of 1-4 Sievert as the limit of basic survivability--the bone marrow shot but recoverable in a few weeks if victims survive those two weeks--what sort of contamination are they suggesting? Whole-body I'm assuming, but for what exposure duration, any?
    by RadioGuy 8/2/2011 5:10:29 PM

  • @Edano , they tried bone marrow transplants. You need a perfect match for that to work.
    by Peter Melzer 8/2/2011 5:11:06 PM

  • Or are they talking internal doses?
    by RadioGuy 8/2/2011 5:12:18 PM

  • OK...I found it earlier in the article... one hour duration.
    by RadioGuy 8/2/2011 5:14:24 PM

  • @RadioGuy , if the exposure was internal through incorporation, I do not think, you stand a chance of getting rid of the radioactivity in time for any therapy to work, unless it had a very short half-life.
    by Peter Melzer 8/2/2011 5:14:48 PM

  • My German is sketchy, but I try to read as much as I can before I translate it.
    by RadioGuy 8/2/2011 5:14:55 PM

  • exactly... so they're talking about those amounts if you were exposed for an hour
    by RadioGuy 8/2/2011 5:15:20 PM

  • I'd run in a very large ciarccle around the 10Sv/hr...
    by RadioGuy 8/2/2011 5:16:26 PM

  • @RadioGuy , yes, that is why the guy used a very long stick.

  • Radioactive Water: Tea Bags To The Rescue
    Scientists here in the U.S believe they’ve found a new way to remove, not just radiation, but other potentially hazardous contaminants to make sure water is safe to drink.
    Dr. Joel Pawlak may have the solution: biodegradable foam. It works like a gooey sponge to pull salt, heavy metals and even radioactive materials like potassium iodide that don’t dissolve out of water.

    “And we really think it’ll work for a lot of the other ions that are created from the nuclear reaction,” Joel Pawlak, Ph.D., a paper physicist at NC State University told Ivanhoe.

    The foam is made from combination of hemicellulose, a by-product of the wood pulp industry, and chitosan that is typically found in crushed crustacean or crab shells. The material can be functionalized to remove contaminants.

    “The material itself isn’t selective for radioactive materials, what it’s actually doing is taking out dissolved ions inside,” Dr. Pawlak said.

    In a disaster, it could be as simple to use as a tea bag.

    “You take a cup of water, place your tea bag into the water and it’ll remove the salt from the water, it’ll remove the heavy metal from the water, and hopefully it’ll remove that radioactivity from the water as well,” Pawlak explained.

    One liter of the foam can turn a hundred liters of contaminated water into safe drinking water. It’s physics and material science that could save lives. The foam may also offer a new option for turning salt water into water that’s safe to drink. Funding for this research comes from several sources, including the U.S Department of Energy.

  • They solve the problem on the big radiation : Japan utility seals area with high radiation level. The operator of Japan's damaged nuclear power plant says an area where potentially lethal levels of radiation were detected has been sealed.

    Tokyo Electric Power Co. said Tuesday radiation exceeded 10 sieverts at two locations near a duct connected to a ventilation stack between two reactor units at the Fukushima Dai-ichi plant. www.google.com

  • @RadioGuy , as I see it, your life is in real danger once you absorbed 1Sv, no matter in what time.
    by Peter Melzer 8/2/2011 5:18:26 PM

  • So, assuming that the 10Sv/hr is actually that, 10 SV at the base of the stack, how far from it should the employees try to stay by inverse squares, given that "20 km" is right out as an answer? What is the minimum?
    by RadioGuy 8/2/2011 5:24:19 PM

  • I discovered an interesting political aspect to the hardened venting of Unit 1. Tepco carried out the action on orders of the Prime Minister himself who is an engineer by education. In the US, I doubt that any president since the inception of nuclear power was qualified to give such order.
    by Peter Melzer 8/2/2011 5:26:16 PM

  • @RadioGuy you have to measure at a second point first and then calculate.
    by Edano 8/2/2011 5:28:08 PM

  • Just reposting this www.tepco.co.jp which is the site radiation survey map from April 23rd.
    by hudebnik 8/2/2011 5:37:59 PM

  • Which they undoubtedly have, but don't release. OK...
    by RadioGuy 8/2/2011 5:38:42 PM

  • when the scource is 10 Sv/h and the worker got only 4 mSv (or 40, as i read) this must have been measured under his protective suit...
    by Edano 8/2/2011 5:38:44 PM

  • On 23rd April the highest reading in that location was apparently 40mSv/hr.
    by hudebnik 8/2/2011 5:40:23 PM

  • @hudebnik ty ! somehow, the figures don't match at all ...

  • Swedish authorities have detained a man who attempted to build a nuclear reactor in his kitchen, Helsingborgs Dagblad reported Tuesday.
    "I was arrested and sent to jail when the police and the Swedish Radiation Safety Authority searched my apartment," the unnamed nuclear enthusiast wrote on a blog detailing his project. "They took all my radioactive stuff, but I was released after a hearing. But I am still suspect for crime against the radiation safety law.

  • IMHO there seem to be 3 possibilities:
    1. The worker had the meter set to the wrong scale and when he saw the reading didn't stop to find out (but Tepco seems certain about the measurements)
    2. The rad surveys in April were totally incompetent
    3. Fresh radiation is still being released
