3 Fukushima nuke plant workers blasted with beta radiation, Mainichi Daily News, August 31, 2011:

At least two workers at the crisis-stricken Fukushima No. 1 Nuclear Power Plant were blasted with more than 15 millisieverts of beta radiation on Aug. 28, plant operator Tokyo Electric Power Co. (TEPCO) has announced. [...]

One other worker with them at the time also likely absorbed a high radiation dose, and his exposure level is now being checked. [...]

The maximum beta radiation exposure to workers during this task is capped at 15 millisieverts, but two of the men absorbed doses of 23.4 and 17.1 millisieverts, respectively. [...]

Beta rays are a type of radiation that can penetrate through the skin and into the body [...]

    beta particles can be stopped by just a few milimeters of aluminium foil/sheet! surely the suits have this layer of protection?? as standard?? what has the iaea got to say about that then???

    “Of the three common types of radiation given off by radioactive materials, alpha, beta and gamma, beta has the medium penetrating power and the medium ionising power. Although the beta particles given off by different radioactive materials vary in energy, most beta particles can be stopped by a few millimeters of aluminum. Being composed of charged particles, beta radiation is more strongly ionising than gamma radiation. When passing through matter, a beta particle is decelerated by electromagnetic interactions and may give off bremsstrahlung x-rays.”

      You see this one?
      how many cameras does Tempco have ?
      countless.. watch the vid.

      The anomoly has that ‘plasma’ look about it, but my nuclear physics isn’t advanced enough to even theorise. So I’ll go with Ocham’s razor and say it might be reflections of something moving coming from the weatherproof cover on the camera.

        Steven,

        The camera that that is taken from is far, far away.
        Most of us have seen, how they zoom in and out with it, like the operator is bored, or just playing around. I just saw a recent one today from yesterday, very strange.. focusing on all kinds of wierd stuff, views of the ocean surf, etc.

        Then back to BSU ( business as usual)
        As far as that particular vid goes, I tend to think those were workers, and the camera was focused far out, and with heat form summer, the heat of the cement, heat from reactors, etc. made the workers images look like ‘ghosts;?
        Purely speculation, but you could clearly tell it was 2 people doing moving about, but what they were doing is anyone’s guess at this point in time.

          I saw that one ..it panned…. in out…each end of the site… it was awesome.
          I do doubt Nuckelchen is into recording…reflections and heat waves.
          Hope that trussing holds up….

    True, but a few millimeters of aluminum isn’t feasible for a protective suit for a person. A Boeing 747′s aluminum wing skin is only 1 to 2 mm thick, and is very rigid. If a “few” mm of aluminum is needed to block beta particles, then I’m assuming they mean more than 2mm is needed. That would be a very thick and rigid suit. I’m not sure how they would bend their arms or legs or fingers in a suit like that.

    And even if they made a suit of armor like a knight would wear, they still need to be able to see and bend their arms/legs. So there are still areas that would be not be protected.

    I hope they at least wear lead vests (similar to when getting an x-ray) but the options are pretty limited for guaranteeing their entire bodies are protected. And that’s especially true for the levels of radiation they are dealing with.

    This is all why we should have thought twice before messing with nuclear technology!

    Maybe Apple can use it iPhone 4 screen technology. From what I hear it’s aluminum doped glass. Maybe there isn’t a big enough demand for suits that protect people from radiation… yet!

    Beta burns were a serious condition for some vicums of the Chernobyl accident…often the result of being drenched with radioactive water.

    Tropical Storm Talas will gather typhoon strength south of Japan before midweek and could ultimately make a landfall as a typhoon in southeastern Japan, west of Tokyo.
    Talas, as a tropical storm or typhoon landfall, would bring flooding rain, damaging winds and potentially inundating storm tides to the southeastern side of Honshu, Japan’s main island.
    On Tuesday, the center of Tropical Storm Talas was still more than 600 miles south of Tokyo; the broad storm was 200 miles to the northwest of Iwo Jima, one of Japan’s Volcano Islands, and was drifting towards the north-northwest at 8 mph.
    On Wednesday and Thursday, atmospheric conditions will be favorable for intensification that should result in typhoon status for Talas. Movement will be mostly to the north with a rise in speed at midweek.
    Estimates by AccuWeather.com forecasters are that torrential rain and high rain of Talas should reach southeastern Japan on Friday.

        Mr Cannonball,

        We have ordered a very nice Geiger Counter set

        http://www.unitednuclear.com/index.php?main_page=product_info&cPath=2_78&products_id=485

        we have all three probes coming as well as a radon-gas detector.

        you are very good with videos and i wonder if you might think about helping this group to host a series of videos.

        the Geiger will be sent around to members here who have video capability. these people will each make a video showing use of the three probes and the readings generated.

        if you would like to help us in some way, please start thinking about what to do in this regard.

        the Geiger should take approximately 2 months to reach ocifferdave, a poster here at enenews.

        a brand-new Geiger will start out at ocifferdave’s house every 2 months where it will spend approximately 3 days with ocifferdave before it is sent down the line to the next person.

        enenews is getting a brand-new Geiger every 2 months. also very interested in this device within the next 6 months:

        http://unitednuclear.com/index.php?main_page=product_info&cPath=2_78&products_id=530

        thank you for your interest Mr. Cannonball

          • Also keep in mind I live in Brisbane which is in the southern hemisphere so I’m not fully sure what the readings here would achieve. We did have some bomb testing in Australia in the 1950′s. Fallout usually falls in the same latitude and I do remmeber reading somewhere that a bomb detonated 3600km from here on the west coast dropped some fallout on Brisbane. I go to Perth, Western Australia quite frequently so maybe I have to fly to Perth and drive up to that area on our west coast?

            I reckon I’ll find a hotspot there!

            Australian Cannonball, i was just thinking that we will need a place to have all of our radiation tests all on one page, or site.

            and was also thinking that if we had them on your site, since you are already world-famous (pretty much), that would be a good thing.

            because i’m getting enenews… (us) a Pro Geiger Counter every 2 months.

            the first one is on the way.

            we will send around at the speed of “priority post”

            every two months we have another, and so on.

            i don’t know if it would be perfect situation, but i ask…

            but in any case, we will need a place to have all the vids in one place to make it nice.

            and then a site could be built around the vids, like graphs and charts showing increases in radiation and so on.

            but for you mr cannonball, i thought mostly like a host.

            even like an announcer… like a sports guy or a news guy… more like a talkshow-host.

            it’s your personality which would compliment our team..

            and we are only just putting that team together now, but we are just the ones who will be doing readings every two months.

            there’s gonna be about 50 of us in the first year, since we’ll each have the counter for 3 days and priority post is around 5 days average?… (i don’t know if it’s really 5 days…)

            anyways, we will not be totally organized but we will be starting to collect these “radiation reading videos” one per week from different locations and we will have a repeat reading every two months on each location.

            i know that when we try to put it all together we can do it. money won’t be a big deal at that time.

            you won’t have to spend money.

            but we all love your personality, and you would be the perfect man to host, and even interview some of us…

            like a host like david letterman, not like a website host that hosts vids, but actually more like both.

            a host like david letterman and a video host. and we could all buy a server if we had to.

            we hate youtube for it’s rules anyhow, why not start something small that can eventually be big.

            cannonball video host.

            cannonballtube.

            think about this in a way where money is not an object… can we do something big?

            we can get out these radiation readings, but can we also start the biggest video channel known to man?

            because people like people who like people.

            i know i go on, but we start simply by doing what is necessary, and we expand that due to need, until we build a channel that is not affiliated with our self-imposed masters.

            we start small, but we start.

          I would like to be put on the list of people who would be ‘down the line,’ keep it for three days, make video recordings of readings, and pass it on. I have noticed regular spikes in southern Arizona beta readings in the EPA website, above the usual 30-50, and daily readings of 100-200 cpm. I sent an email to the EPA lab contact, and he merely sent back a short note saying these were normal background fluctuations. Oddly, I didn’t believe him. It would be nice to have the means to do one’s own readings every once in a while. I would be happy to contribute towards the effort.

        Thank you stukncali

        I encourage everyone in Japan to study what radiation does to the air, water, ground, the effects, and how long radiation lasts.

        Make wise choices for you and your family. Do not depend on what is told to you. Investigate for yourself on the effects of radiation in your environment.

        Chernobyl comes to mind, start there in your research remembering that your disaster is much worse.

        I do not believe that you alone in these dangers, this is a global problem.

        With the jet stream and people traveling back and forth, there is going to be a wide spread of contamination.

    just saw this in NHK….
    TEPCO finds possibly active faults near Fukushima

    Tokyo Electric Power Company suspects there are 5 active faults near the Fukushima Daiichi nuclear power plant that could affect the crippled plant if they cause a tremor.

    TEPCO made the discovery after the Japanese government requested utilities and nuclear agencies to reexamine faults around nuclear plants.

    The directive followed a strong earthquake on April 11th from a fault thought to be inactive, 50 kilometers from the Fukushima plant.

    TEPCO said on Tuesday that geological deformations were observed for the first time at 5 faults, suggesting they are active.

    The utility will continue drilling to investigate the conditions, though the firm believes any tremors would be within the quake-resistance standard.

    Besides TEPCO, two nuclear agencies reported 9 faults near their nuclear facilities in Ibaraki Prefecture that could be active.

    Fukushima nuke plant workers irradiated on job ignored alarm: TEPCO

    Two workers exposed to high doses of beta radiation at the crisis-stricken Fukushima No. 1 Nuclear Power Plant on Aug. 28 were ignoring their dosimeter readings, plant operator Tokyo Electric Power Co. (TEPCO) announced on Aug. 30.

    The two men were both blasted with beta radiation while they and one other worker were replacing filters on a water decontamination system at the plant — a task that requires pulling components out of the water. TEPCO stated that they ignored the radiation count on their dosimeters and continued to do the filter replacement despite absorbing radiation doses of 23.4 and 17.1 millisieverts respectively, exceeding the 15-millisievert limit for the operation.

    According to TEPCO, the men’s radiation alarms sounded when their doses exceeded the 15-millisievert maximum, but they decided to complete the task with the help of the third worker as they had very little left to do. The utility also said the men’s radiation control manager was not present at the time. Testing revealed the third worker absorbed a 1.1-millisievert dose.

    Beta rays are a type of radiation that can penetrate the skin and enter the body, and total exposure is legally limited to 1,000 millisieverts.
