People got around 10 particles each in Tokyo. The data is from air filters in Japan and the West Coast.

People in Seattle got on average 5 hot particles per day for the month of April, 2011. (acc. to Arnie Gundersen, Fairewinds Associates) Question: What's the known effect of around 5 hot particles a day? The most I can find is the following, indicating a "big" risk of leukemias and cancer -...

Good idea. I'm assuming a vapour release [almost always?] carries radiation with it in this situation? Now, how to get a reliable set of data - obviously not from TEPCO (not picking on them, but I'm afraid credibility there really does approach zero - they're trying to manage things on...

Well, I did find this explanation - for the Unit 4 vapour release of June 14 (Japan's June 14 - it was June 13 here in N America): http://ex-skf.blogspot.com/2011/06/fukushima-i-nuke-plant-live-camera.html The water in the spent fuel pool of the #4 reactor is not getting cooled as much as...

It is the Japanese raccoon-dog, called a tanuki. http://en.wikipedia.org/wiki/Tanuki We call him a "radiation detection device", or just Rocky. Despite not wearing a respirator or hazmat suit, he is able to scamper about the Unit 1 area with seeming impunity. (We did have him on the run...

Here's a detailed map, well labelled, of the Fukushima complex: http://bravenewclimate.files.wordpress.com/2011/03/fukushima_daiichi_map_plan.jpg A couple of spelling errors, but a very good map: "Radioactive [sorid] waste treatment facility" "[Techinical] and Skill Training Center" --unless...

There is still a TBS JNN Live Feed http://www.youtube.com/user/tbsnewsi#p/l/ZIa6yble2gk It gets taken down from time to time. It went down during the large release I mentioned earlier.

A+, with honours. :D

A+. You got it.

I'm well aware of the tower and the optical illusions thereof. Yes, the vertical tower can be mistaken for a vertical plume of smoke, but this isn't what I'm talking about at all. Take another look at your "fog". This is the third hour of the event: 2011.06.14 03:00-04:00 / 福島原発ライブカメラ (Live...

No fog that day. We checked the weather - realtime. Conditions were cloudy. Unless fog starts inland from the top of a building and rolls out to sea? Also, you'll see two vertical plumes - one from #3 and one from #4. You'll also see flashes of light within those plumes - but, have to...

You'll notice that actually #3 and #4 are steaming in those videos.

Have a look at the following videos. I'll drop this topic very shortly, but I do want some kind of corroboration, given that this board's topic is: Physics Forums > Engineering > Nuclear Engineering > Japan Earthquake: nuclear plants. This was not - a false alarm - one of the many...

I gather nobody actually saw the large release of steam - very large - last night. We know it is steaming every day but this was far above the normal. Definitely not fog or clouds. This was a large, fast moving vertical plume of smoke coming directly from #4 - top of roof. It eventually...

I'm afraid to ask this question, having not assiduously followed previous threads, but will try to phrase the question in the most learned and scientific way I can think of: Why is Reactor #4 smoking? http://www.tepco.co.jp/en/nu/f1-np/camera/index-e.html (LARGE amounts of steam...
