@Nancy @Peter Melzer Certainly alpha radiation affects CCD chips, there are videos on youtube that show this.
by Bobby1 5/19/2011 12:53:57 PM

@Nancy , sure, I sent my references to Dean a few days ago.
by Peter Melzer 5/19/2011 12:57:01 PM

@Bobby1 , the alpha particles would have to settle on the chip to be detected because of their short traveling range.
by Peter Melzer 5/19/2011 12:58:22 PM

@Peter Melzer It could have been caused by plutonium particles in the ambient air.

@Bobby1, there is a lens in front of the chip. It is difficult for dust to reach the chip.

Failed venting tries linked to No. 2 damage search.japantimes.co.jp "Two failed attempts to vent steam within days of the March 11 quake and tsunami most likely resulted in damage to the containment vessel of the Fukushima No. 1 power plant's No. 2 reactor, a Tokyo Electric Power Co. source said Wednesday.

This latest revelation casts further doubt on the crisis-management capabilities of the plant's operator, already put to shame by the release of massive amounts of radioactive material into the air and contaminated water into the ocean."
by Markfm 5/19/2011 1:03:45 PM

Okay, all radiation shows up on a CCD even Xrays, the reason alpha radiation is so easy to see is mainly because: A an alpha particle is big, B an alpha source of sufficiant strength are available to the public, powerful gamma sources are not.
by WolfDK 5/19/2011 1:03:55 PM

@Peter Melzer Digital cameras are not hermetically sealed, it is easy for very small particles to enter the interior.
by Bobby1 5/19/2011 1:03:58 PM

@Bobby1, the CCD chip is hermetically sealed, for alpha to show you have to cut the chip open

Cabinet adviser retracts remark about release of contaminated water mdn.mainichi.jp The advisor is a playwright, not a nuclear technical person. "Hirata, 48, said in the statement that he has not visited the prime minister's office since the March 11 earthquake and tsunami, and that he is not in a position to know about developments in the nuclear crisis."
by Markfm 5/19/2011 1:10:08 PM

@Bobby1 , if that happened, the camera would continue to show these blitzes, even when used elsewhere.

Workers enter No.3 reactor www3.nhk.or.jp "TEPCO says the workers measured radiation of 160 to 170 millisieverts per hour around the door of the containment vessel.

The utility says it would be difficult to start work on injecting nitrogen gas needed to prevent a hydrogen blast into the containment vessel under such high radiation levels."
by Markfm 5/19/2011 1:38:19 PM

Workers find pools of water at No.2 www3.nhk.or.jp Radiation levels much lower than in #1. "The workers found three pools of water on the floor, and saw water dropping down from above in some places.

The presence of so much water is apparently due to the condensation of steam rising from the spent fuel storage pool on the upper floor."
by Markfm 5/19/2011 1:40:10 PM

@all making references to the original EQ and tsunami, in respect to damages, you need to review this doc. Japan had 111 earthquakes from March 11 to March 31, all 4+ and higher. www.tsunamioftears.com For the specific detail on these use this: www.tsunamioftears.com (very frightening)

@Nancy Could you pin point where the radiation can be seen? I don't see anything.
by Pedro Jesus 5/19/2011 1:49:12 PM

@Pedro Jesus on some you need to look at the large view to see it. It looks like missing pixels or colored dots. This image has visible radiation even on the small image. The first image on the page from outside, if you click on it to get the huge view you can see the white spots all over and by the right of the image where the grey steel structure is there is a concentration. www.houseoffoust.com
by Nancy via Houseoffoust 5/19/2011 2:02:24 PM

@Nancy You mean the golden dots? Well that cannot be visible ionizing radiation because they're glowing on the wrong visible spectrum. Visible ionizing radiation glows green or blue, not orange (yellowish). Also the size of the spots is completely out of proportion. You shouldn't be able to see the glow with that resolution. It would require a far higher resolution to see any spots, if that were ionizing radiation reacting with matter (the only way ionizing radiation can emit photons on the visible spectrum). There's got to be another simpler explanation for those spots. I'm not saying there isn't radiation emissions in those environments (we know there is from the readings) but it wouldn't show on common digital cameras.
by Pedro Jesus 5/19/2011 2:15:35 PM

@Bobby1: That's a very good link. That's the stuff we should be talking about. Not just..Tsunami reached 41 minutes, 45 minutes...and we have no video if #4 blowing up etc...etc. Far less discussion is about what are the health effects, who are the most prone folks and how can tehre be any mitigation of radiation impacts on human health..
by Optim 5/19/2011 2:17:57 PM

@Pedro Jesus Look at some of the other images posted, they show what your describing.
by Nancy 5/19/2011 2:20:05 PM

@Optim I agree. This should be the main focus of this board at this point. The whole planet is threatened.
by Bobby1 5/19/2011 2:28:41 PM

Just before shutting down last night, I looked at the live cam and my split second
reaction was "wow, they are putting a tent over 2" Then I realized it was a
reflection. Just one of those oddities that captured my eye, and it put some perspective
on what it would be like for TEPCO to tent the reactors. Visualizing that "tent" being
moved over the building.

by deb 5/19/2011 2:29:16 PM

@Optim @Bobby1 the purpose of the board you can find here www.scribblelive.com is to discuss the humanitarian aspects of the disaster . You will also find that members are very knowledgable about the earthquake/volcanic aspects too. This board is just for the techi/news aspect
by elainekirk 5/19/2011 2:30:26 PM

@Nancy Not really, Nancy. Anyway, regular cameras cannot capture ionising radiation unless they're pointing at a good source of radiation so that all the interaction with matter in suspension produces a visible glow (usually green), commonly known as Cherenkov radiation. Isolated radioactive particulates in suspension (like the photos suggest) do not radiate enough photons for their interaction with particles in suspension to be captured at these resolutions. You can scrap that idea. Also, see the Youtube video on the first link with an experiment and you'll understand why these multicoloured spots on these pictures cannot be radioactive particulates in suspension. And you can also research Cherenkov radiation. We've been through this before many weeks ago. But, nice pictures anyway. =)
by Pedro Jesus 5/19/2011 2:41:12 PM

@Nancy You can delete after you read: Want to say how much I appreciate all the work you and radioguy have put into the group website. In looking at the outline, my recommendation would be to also have something that has information on how to protect yourself in an emergency situation, as well as the long haul. An example would be that water filtering system made from a 5g bucket, cloth, clay and pebbles, I posted a while back. What can I do for long term protection and what can I do in an emergency (my thought process is to help the people swindled into believing radiation is safe, and who won't be prepared in a crisis.)
by deb 5/19/2011 2:44:07 PM

Would it be possible to do a major clean up on the pinned items? I am working on embedding the tech blog into a page on the website and you can't get the comments to show up without scrolling even with a really long window. Would people be OK with maybe moving some of the non-critical content over to the faq wiki?
by Nancy 5/19/2011 2:48:06 PM

@nancy that would be great by me as I think visitors in many cases fail to find the conversation :)

@Nancy Unpin away!
by Rob in SF 5/19/2011 2:52:00 PM

@nancy - that's fine by me. I just have to reprt Google's translation of one of the headings on Tepco's status page today.... "Road accidents for the convergence of the Fukushima Daiichi Nuclear Power Station," Progress Report (May 17)" Many a true word...
by hudebnik 5/19/2011 2:52:27 PM

@Pedro -- Possibly transient effects on the imagers? For example, see pages 14-15 of radhome.gsfc.nasa.gov Figure 8 lower 2 images show the effect of "peppering" by protons.

Please take a moment to review Meretisa's research work on potential group names. We need feedback so a list of best choices can be made by Sunday in order to being voting for a name. Let us know what ones you think may work. docs.google.com

@nancy - I'm afraid that none of them really does it for me. How about Global Energy Action Network?

May 17, 2011 Update – NRC Issues Bulletin
As of May 15, 2011, Worker's exposure dose: 30 workers have been exposed to radiation more than 100 move as of 5/11. *Emergency exposure dose limit has been set to 250mSv.

The current situation by Joe Miller (Remember much of this is speculation based on the information that I have and experience)

The nuclear regulatory commission issued Bulletin 2011-01 on May 10, 2011 entitled " NRC BULLETIN 2011-01: MITIGATING STRATEGIES". This was expected. The bulletin requires the nuclear utilities to respond according to code of federal regulations (CFR). I expect another bulleting later this year after lesson learned are digested by NRC. At the utility, when it comes to requests from the NRC, the NRC bulletin gets the most attention from the licensing and engineering staff. Also see NRC Information Notice No. 11-05 “Tohoku-Taiheiyou-Oki Earthquake Effects on Japanese Nuclear Power Plants,” March 18, 2011, ML110760432. Inspection report summaries are provided at www.nrc.gov .

The website is partially done. I will make an attempt at adding the static information about the reactors and power plants (historical information and stats) but will then need people to help me with adding in what I may have missed. We also need to establish group information for the about page, so we need to get the group goals and mission statement a bit more figured out. We will need content for all of these sections on the site. They can be done as blog posts about that subject so please be thinking or writing for those. Group content should be reviewed before it goes live on the site. Tenzig had suggested maybe having people pin an article for review before it would be published as group content. Individual user diary posts don't have to be group reviewed but should be on-topic, labeled as that individual's diary & opinions and within the scope of the group. You can see the progress here: houseoffoust.com
