Japanese earthquake / tsunami discussion

i was listening to a podcast last week where a bunch of british scientists were briefing (afaik) embassy staff and others in japan on the current state of affairs at the time and the general gist of it was, that when they were told that the current levels of radiation posed no health risks to the public, questions were asked about how reliable the information was that they were receiving and if 'we' (being the international community i guess) could be sure 'they' were being honest about it, and the reply from one of the scientists was that it was all being independently monitored by the scientific community both at 3rd party monitoring stations around the world and and using the data from japan's own monitoring stations, so basically, they couldn't fake the levels even if they wanted to.The world. The US Military. Radnet. Any crazy worried civilian with a geiger counter. You name it!
And all those other energy comissions which im not learned up on.
i came across this before and after satellite photo of a town in japan that has pretty much been totally wiped off the map.
http://earthobservatory.nasa.gov/IOTD/view.php?id=49684
there's hi-res colour adjusted images showing the town and surrounding area and its just been totally obliterated.
there's also a bbc report from what's left of the town and there's practically nothing left.
http://www.bbc.co.uk/news/world-asia-pacific-12801085
the report is about how they couldn't get their floodgates closed and that the fire chief had complained about inadequate defences after a previous tsunami, but looking at it i don't think anything could have saved the town.
its heart breaking to see the looks on their faces, they just don't know where to start to try and pick up the pieces, they're just going through the motions searching for people because that's all there is for them to do.
you just can't imagine what it must be like for them knowing that so many people they knew are gone, family, their home, everything and all they can do now is suck it up and carry on to pick through the debris looking for whatever bodies they can find so they can at least have a decent burial.0 -

"10:23 a.m. Monday ET, 11:23 p.m. Monday Tokyo] The U.S. Navy is moving the aircraft carrier USS George Washington from its port at Yokosuka Naval Base near Yokohama to avoid radiation exposure."
Yokosuka is in Tokyo Bay... so it looks like the Yanks think Tokyo is due to get a dusting of radioactive particles from the plant, as the wind swings to the northeast. 0 -

no scaremongering there then
Don't think it's news to people in Tokyo, they've been expecting 'the big one' for decades and have built almost everything to be able to withstand a direct 7+. Hopefully that would be enough, but people are always gonna expect the worst I think.Rob A.

Tokyo is to the south of Fukushima and the wind is going to the northeast as you say, so seems a bit strange they'd move it to avoid radiation.. hopefully they don't expect the wind to start blowing south any time soon

you got it wrong man!
tis the other way round.
a northeasterly is wind blowing from the north east.
for wind to start blowing south, as you say, the correct term is a northerly.
The predominant wind in ireland is a south westerly, ie coming in from the atlantic.0 -

as they somewhat ironically sit in safety aboard a giant aircraft carrier that has two nuclear reactors of its own.Rob A.

Fukushima radioactivity reaches Europe... in miniscule amounts.
"Minuscule numbers of radioactive particles believed to have come from Japan's crippled Fukushima nuclear power plant have been detected as far away as Iceland, officials revealed last night.
Traces of iodine-131, below levels of concern for human health, were discovered in an air filter used at a radiation monitoring centre in Reykjavik at the weekend, the Icelandic Radiation Safety Authority (IRSA) said."
http://www.independent.ie/incoming/incoming_dailyfeed/tiny-traces-of-radiation-detected-as-far-away-as-iceland-2590522.html
The Meteo France model of the radioactive spread seems fairly accurate, so we can expect some traces here too.

i hate to say it, but a lot of us have been following the advice from all these scientists saying that there would be no danger to public health from the reactor problems, but its looking increasingly like that just isn't the case.How so? Are the plants still leaking? Spent fuel pools boiling off?
i'd hope that its a very temporary situation given the half-lifes of most of the isotopes involved so fingers crossed once all the reactors are all under full control again and no longer spitting out whatever it is that is causing the contamination, all they'll need to do is wait for the isotopes to decay in a week or so after that.
fingers crossed. 0 -

Realizing though of course that the levels being detected haven't been of any or much concern to human health outside of Japan. I think at the worst you might see precautionary measures taken to clean/discard some crops and things.i hate to say it, but a lot of us have been following the advice from all these scientists saying that there would be no danger to public health from the reactor problems, but its looking increasingly like that just isn't the case.

Thing is, the IAEA and the Media aren't withholding information, they just aren't getting enough. Japanese officials aren't forthcoming with updates saying they need more time to declare the situation stable. Knowing the Japanese though, that could mean anything. They're very "Don't Panic, bring a towel". I think it's as much a case as things may turn out alright at this point but they don't want to give any false hopes, so they're sticking to the facts and nothing but the facts.I must say the media is doing a bang up job of covering over this story. The situation seems to just get worse.
All the while though I'm perfectly aware I woke up this morning to potentially minimally elevated levels of background radiation. It's not something which presently has me concerned. I lost far, far more sleep when NASA launched Cassini.0 -

MMmmm there is hope and then there is reality. I feel its going to be far from a 'temporary situation'... the question now is how many square kms of Japan will end up uninhabitable for years.
All radioisotopes have a half life... the time it takes for any radionuclide to lose half of its radioactivity—and eventually all radioactive waste decays into safe non-radioactive elements.
Some of the common isotopes in the radioactive contamination
Iodine-131 half life 8 days
Caesium-137 half life about 30.17 years
Strontium-90 half life 28.8 years
But also a whole soup of others, perhaps including some isotopes of Plutonium from the MOX fuel in reactor3, like Plutonium-239 with a half-life of 24,100 years !0 -
