As far as I know, about half an hour of exposure to 750 rads can be fatal. Don't quote me on it tho.

Yes, that's exactly what I was thinking too .

Surely the Japs all ready have some sort of super advanced contingency plan for something like that.

They are now mostly sure that one reactor has melted down. They are hoping that the RAD containment building will hold up.

Oh yes, the Japanese cooked up the earthquake that made the tsunami that killed thousands of people and caused billions of dollars in damages and made their nuclear power plant melt down. Oh yes, the Japanese saw all this coming.

That was no Earthquake.


Apparently a few dozen people total have been exposed to radiation. That'd be tough knowing that you now have a significantly higher chance of getting cancer.

If Japan turns into a wasteland and people go there for a Fallout-esque adventure, then we might actually have found a way to weed out stupid people from society.

Other then that, the reactor really has me worried. I have a number of friends that live down there :(.

Neighbour countries don't have to worry about radioactive clouds as long as the reactor doesn't explode in the Chernobyl style (which is very unlikely considering quality of Tsukushima reactors, much superior to the scamped and dangerous Chernobyl PP). Sadly 160 people have been already affected (according to massmedia). I can only wish them to cure as much as possible, there have already been enough victims of this earthquake and mutants (fingerless, limbless, etc.) born due to the radioactive contamination (from Chernobyl or over 2000 nuclear explosions).

so it's something like the second japan fallout after hiroshima-nagasaki? O_o

From what I've read (which might not be the most accurate source), the Self Defence Force had already sent in a couple waves of soldiers attempting to shut down the reactors, and apparently, some of them had already died because of radiation poisoning.

Hope they put them into some protective gear, otherwise it sounds kinda insane...

The thing is, they did. All that suits and what not; they've even dispatched 4 NBC warfare-capable vehicles. And still......

Japanese police are warning that the death toll could hit over 10k from the Miyagi region alone, they're also now pumping seawater into the reactors in a last ditch attempt to cool them.

Oh and heres a list of the most poweful earthquakes since 1900, 8.9 is seriously powerful, It's almost lucky it hit japan, a country well developed enough to have alot of protection against earthquakes, had it hit a lesser developed region the destruction would have been total and absolute.

I call bullshit. Here is a pretty in-depth (although admittedly now slightly out of date) analysis of what happened by an MIT research scientist (scroll down to "This is his text in full and unedited. It is very long, so get comfy."), and why there is absolutely no cause for alarm. Most of the scare stories you hear are almost certainly the media going crazy.

Tl;dr(ish) version (radioactive element release bits in bold):
- Tsunami took out diesel generators used to cool reactor. Backups brought in did not work.
- Priority of people working on reactor switches to "keep the coating around the fuel rods and the pressure vessel containing the reactor intact".
- Pressure inside pressure vessel increases due to the water surrounding the reactor core heating up.
- Steam deliberately released from pressure vessel through pressure release valves in order to preserve integrity of pressure vessel.
- Radioactive N-16 and noble gases exit pressure vessel along with steam. Half lives of radioactive material no more than a few seconds.
- Water level falls below level of fuel rods (briefly), causing coating around fuel rods to be damaged (very slightly).
- By-products of Uranium decay (radioactive isotopes of Iodine and Cesium) begin to mix with the steam in VERY small quantities (although the temperature is still too low for the Uranium to melt).
- Iodine and Cesium released along with steam, in tiny quantities. As the article author puts it, "If you were sitting on top of the plants’ chimney when they were venting, you should probably give up smoking to return to your former life expectancy." In any case, these decay products will have been carried out to sea, far from humans.
- Detection of Cesium and Iodine causes engineers to change to plan B: since distilled water cannot be added to reactor fast enough to keep water level above fuel rods, sea water is used to cool reactor instead. At this point the danger of a melt down passes.
- The sea water used to cool the reactor will be slightly radioactive, but this is contained in the reactor and can be processed and disposed of safely.

By the way, the main earthquake got lifted up to 9.0, it's thus the fourth most powerful earthquake in the last 100 years, sharing its place with the Kamchatka quake from 1977.

Yeah that's not accurate.

You can't send in forces to shut down a plant that's been flooded and does not have electrical power. On the contrary, the problem is that the plants don't have power, so the cooling systems are not working. To make sure the reactors don't overheat and melt the containers and release harmful radiation to the environment, the plant operators have been forced to pump in sea water, and release it when the water becomes heated into steam before they have a steam explosion.

They've evacuated everyone from the area around the plants, so nobody is in imminent danger. The questions that remain are a)how quickly they can restore power to the power plants to get the cooling systems running, and b)how much of an impact the radiation will have. Apparently there have been traces of radiation about 60 miles east of Japan, but the US Nuclear Regulatory Commission says there is no danger for any residents of the Western US, Hawaii, etc.

Quick point to note. If a nuclear reactor uses seawater in its cooling, the reactor has been written off. Don't expect these reactors to ever run again. Main reason = they're flooded by seawater, and the reactor corrodes away in double time. Utterly dangerous, and utterly useless. The Japanese are trying to minimise losses now, but the plants are certainly 'losses'.

What a terrible disaster, I hope that the people over there recover.

I was browsing another forum and found this, I am enraged by what's been saidhttp://apina.biz/39128.jpg how can people by so ... heartless?

Heard on the radio today that the 3rd reactor at the Fuku went bang from hydrogen.

Merely the outer containment building. The reactor itself probably only has some debris and scorchmarks on it.

Kichō, on 14 Mar 2011, 8:01, said:

Your link doesn't seem to work.

Well a second tank blew up now, this one looks much more like a real explosion Oo .

It's presumably due to the hydrogen and oxygen that has built up - this is the sort of thing the pressure vessels are designed to handle. AFAIK the reactor is still intact after the explosion.

Wiki says the 1st and 3rd containment buildings blew up by hydrogen buildup.

update: the tsunami wave also hit Papua. no epic major damage, but at least 30 villager huts were damaged, several fishing boats missing, and four bridges broken.
