    Probability problem, independent events

    If there is a 5 percent chance of getting a particular result, and there are 15 of these events taking place simultaneously with the exact same probability, then collectively, what is the chance that one of these events will take place? For example, if 15 cars of the same make and model...

    Japan Earthquake: Nuclear Plants at Fukushima Daiichi

    Neutrons would account for the discrepancy with the cumulative dose as stated by tepco, since most of that dose would not be picked up by dosimeters used by subcontracted employees. And with over 3000 workers on site, the quality of some of those dosimeters may be in question, no? Also...

    Japan Earthquake: Nuclear Plants at Fukushima Daiichi

    Anyone want to field some conjecture as to why a second worker dropped dead under similar circumstances with that other fella who came down with acute leukemia? Tepco has ruled out strenuous working conditions (he worked for just 3 hours a day), and has his cumulative exposure at just over 2...

    Japan Earthquake: Nuclear Plants at Fukushima Daiichi

    No, though we hope the above statement doesn't turn out to be a real life eventuality with any of the tepco staff. The long term viability of storing water is also in question, and though i am not professionally in a position to field any recommendations, it sometimes helps to hear...

    Japan Earthquake: Nuclear Plants at Fukushima Daiichi

    Also, if filters reach capacity every 5 hours (assuming that is the worst case scenario), they will be going through roughly 3600 cartridges per month. I wonder if our friends at Kurion have planned for the possible eventuality of supplying many thousands of cartridges over the next year or...

    Japan Earthquake: Nuclear Plants at Fukushima Daiichi

    1 of 24 cartridges reached capacity within 5 hours time. Given the volume of water and Cs content therein, we can speculate that under normal operations, after every 5-10 hours an additional cartridge would max out and require manual removal. Let's face facts - this water cleansing operation...

    Japan Earthquake: Nuclear Plants at Fukushima Daiichi

    Everyone is concerned about how the typhoon would detrimentally effect operations at the plants, well it seems to have obliterated in-air readings around Iitate. Much lower, for now. http://www.falloutphilippines.blogspot.com/ On seasonal Japan wind changes and precipitation, just basic...

    Touche. Some people have trouble making reality conform to their thesis.

    They explicitly stated "thyroid equivalent dose", from the pdf. They have already corrected for thyroid uptake.

    Japan Earthquake: Nuclear Plants at Fukushima Daiichi

    Whoa, NISA comes clean about isotope ingestion resulting in considerable exposures to thousands who were involved early on at Dai-ichi. http://mdn.mainichi.jp/mdnnews/news/20110521p2a00m0na021000c.html Some dose calculations these poor guys got, or are expected to get...

    Japan Earthquake: Nuclear Plants at Fukushima Daiichi

    Weeks ago, someone mentioned the very first message in this thread (above), and how things have changed so little with Tepco that this comment is still very appropriate today. Ringing truer than ever.

    Japan Earthquake: Nuclear Plants at Fukushima Daiichi

    Greetings all. I have a very simple question that is yet to be addressed: Is all the smoke, steam or whatever the composition of the discharge we are viewing on the live feed normal as of late? Seems like it may simply be a product of ongoing and recently increased water injection efforts.

    Japan Earthquake: Nuclear Plants at Fukushima Daiichi

    The http://www.nanosense.fr/ENGLISH/produits/radex-fiche-EN.pdf" state the upper range x/gamma detection at 1.25 mev which is more than adequate for cs137, but efficiencies are not stated. I've always wondered whether the manufacturers understand the limitations of their device and correct for...

    meant to say "an electron in the 0.5 mev range" would efficiently be giving up its full dose at about a 1/2 - 1 cm depth.

    Japan Earthquake: Nuclear Plants at Fukushima Daiichi

    I'll be in the Philippines until June. Using http://www.radprocalculator.com/Beta.aspx" to calculate the dose. I'm almost positive these values are given in air; also assuming ingestion and so-called bragg peak, an electron at 0.5 cm would efficiently be giving up its full dose at about a 1/2...
