Reactor meltdown possible in Japan.


Recommended Posts

back on topic....

  1. 0331: A fire which broke out Tuesday at Fukushima has now been extinguished, media reports say.

Trying to make sense of all of this? Was there another explosion or not? Did they see steam rising from the fire fighting?? Info seems to have dried up....did they kill the cameras on the plant??

lol.. ppl can claim citizen reporter are better than CNN an the fact that fox was making stuff up as recently as last night is not allowed to be mentioned? CNN has done fine given what their resources on the ground are.

They could get news out quicker if they would just read this thread.

They could have at least carried the live press conference which had important information... instead they had AC wanking over there.

And what's with standing on debris piles where people are buried, just to make a point about the catastrophe? American reporters are short on brains.

0324: Helen Creak, who works for the Japan Exchange and Teaching (JET) programme in Yamagata prefecture, tells the BBC: "It is difficult to make rational decisions when we aren't getting honest and accurate information from the Japanese officials or news stations.

.....and I thought it was just me misunderstanding.....

That doesn't even make any sense. It's really odd that you'd react to a comment about CNN like that in a thread about a world tragedy. CNBC has kicked their butt tonight and everyone else. That's not a political statement, please don't try to make it one for whatever reason.

Nikkkei down about 10%. Air China cancelling flights to Tokyo. Markets getting crushed including US Futures.

Old but decent photos.

400 mSV is nothing to sneeze at....your starting to get in significant cancer risk category...not quite to the level of acute toxicity though. I hope they rotate them well and give them good suits....

Do you know where 400 mSV would fall into this chart that is measured in Sv?

http://en.wikipedia.org/wiki/Radiation_poisoning

Also, how much in rads is 400 mSV equivalent to? I am a bit confused. Thanks.

They show what viewers watch. Edited segments are more impactful for the casual observer than a half hour talk with 1 minute of big news.

0337: A low level radioactive wind could reach Tokyo in 10 hours, Reuters is quoting the French embassy in the Japanese capital as saying.

The Japanese, are telling the French, who are telling the Brits (Reuters/BBC), who are telling us.

How do things get muddled again?

... then learn to read thread titles? Cluttering up this thread with economic news when this thread is about a reactor meltdown doesn't make sense, especially when this thread is pushing 1,500 posts (and there's no need to be an ass either, I'm trying to help, especially if you want to actually discuss the economic issues).

They show what viewers watch. Edited segments are more impactful for the casual observer than a half hour talk with 1 minute of big news.

Maybe they need to change because most of the ratings I've seen have them pretty far behind the competition. Not having a guy like Miles Obrien on the payroll hurt them in the last day or two. The "experts" they've had on....one earlier tonight couldn't even accurately circle reactors on the screen. I miss guys like Bernard Shaw who if they were still around I'd have been glued to the tv watching. OT, but they've lost a ton of good people to retirement and other networks.

CNBC World just left by saying one of the burbs of Tokyo is at 40x normal radiation. Quoted Kyodo although I don't see it on their site.

Yes, 40% of the minimum. The LD50 appears to be about 6SV with medical care, so levels appear to be at less than 10% of those levels currently (LD50=50% of the population exposed to that amount of radiation would die).

I think that chart is really discussing acute toxicity...and not cancer risk. I'd imagine cancer risk is very elevated with something like 400 mSV. That's like 15 CT scans.

This is straight from Wiki, but it looks correct, from my basic understanding. When I first learned radiation 5 years ago in my emergency response classes, we learned in rems and rads, and I know I have seen other people confused by units.

conventional unit: 1 curie = 37 billion disintegrations per second.

SI unit: 1 becquerel = 1 disintegration per second

conversions

1 curie (Ci) = 37 gigabecquerel (GBq)

1 gigabecquerel (GBq) = 27 millicurie (mCi)

conventional units: A dose of 1 rad means the absorption of 100 ergs of radiation energy per gram of absorbing material

SI units: A dose of 1 gray means the absorption of 1 joule of radiation energy per kilogram of absorbing material

1 Gy = 100 rad

1 rad = 0.01 Gy

1 roentgen ® = 258 microcoulomb/kg (µC/kg)

1 millicoulomb/kg mC/kg = 3876 milliroentgen (mR)

Dose equivalent

The dose equivalent is a measure of biological effect for whole body irradiation. The dose equivalent is equal to the product of the absorbed dose and the Quality Factor.

The Quality Factor (Q) depends on the type of radiation:

X-ray, Gamma ray, or beta radiation: Q = 1

alpha particles: Q = 20

neutrons of unknown energy: Q = 10 (If the neutron energy is known, see more specific Q values at 10 CFR 20.1004 [1])

conventional units: dose equivalent (rems) is the product of dose (rads) and Q

SI units: dose equivalent (sieverts) is the product of dose (grays) and Q

Conversion

1 Sv = 100 rems

1 rem = 0.01 Sv

nik in a complete free fall, down nearly 1300, i wonder if they are getting news we aren't. Flow of info really seems to have dried up.

Seriously.. There is a economic thread now

It's all related, what other news is causing that rapid a sell off? There are contradictions everywhere.

It's not cool to act like a d*****bag and blatantly disregard attempts to keep the thread on topic.

I didn't want this thread to break off from the main EQ thread, but I am glad it did now. I agree, lets please try and keep this contained to the power plants, and not the greater economic waves.

Do what you want then.

I may start talking about Libya in here later too.

Thanks for the useful variables. I have a question, though: The radiation that was released from reactor #2 is alpha-, beta- or gamma-based?
