Rad is quite obsolete radiation unit todays. We now are using Grays

100 rads is 1 gray, and 5 grays leads to death in 14 days.

And here we have... oh.

The situation is very dire : under the last information the explosion would be caused by the coolant.
Th coolant of the first circuit, under direct contact with he core. Without this the reaction could not sustain itself but the core could melt anyway (not explode Chernobyl style, just melt due to remaining heat).
Leakage of radiation is already confirmed, but the scope of the damage caused by the explosion is not.

The explosion (probably caused by hydrogen buildup) stripped the walls off the containment building, only the metal framework remains.

HOLY MOTHER OF MERCURY! IT'S GONE!

The reason the backups failed is interesting. The reactors shut down and the backups started correctly after the quake. But these two power plants are placed right at the eastern coastline for access to water, and are completely exposed to the pacific. So the tsunami came and apparently that's when all the backup generators failed.  They managed to run the backup backup coolant system on battery power, but it's not as efficient.

Over 1 Sv (Sievert) may lead to death (5-50%)
What is worse. This map is a bit strange.

Let's hope nuclear reactor failures won't turn into a chain reaction.

It is impossible - to start chain reaction critical mass of radioactive material is needed.

This vid is pretty insane.

...Is it bad that I snickered at all those '...aaaaaAAaaa...' sounds there?

I'm sorry.

100 rads is 1 gray, and 5 grays leads to death in 14 days.

This book by the deputy chief engineer of the Chernobyl plant, provides a testimony to a contrary. E.g. on page 250, we hear of one radiation poisoning patient, who received roughly 10000 rads, and lived for 54 days.
On the other hand, it's the Soviet Men he's writing about.

Anyway, that picture is a pile of bullcrap. The Chernobyl accident irradiated Pripyat inhabitants and cleanup workers with roughly 100 mSv(source) on average, with a few cases of over 250mSv(assuming alpha decay as the main irradiatin factor from fallout, and adjusting for the most vulnerable organs, it translates to no more than 4(100mSv)-10(250mSv) rads.
If you were to believe the numbers in that picture, the plant would have to vaporize itself in it's entirety, and then some.
I'm no meteorologist, I don't even know where to look for this data, but isn't that wind pattern characteristic of surface winds, with high-altitude ones going the other way around? At least that's what I remember from high school geography lessons.
The "Australian Radiation Services" is a private company specializing in handling radiation hazards, who's logo has been most likely hijacked by some fellow with trollish intentions.

Did the water get into the airport terminal/whatever the building is?

[Kogut]

rather 0:24

Oh man, I just noticed that guy running from the flood in the street.  Took me a few replays of that spot to see him.

[DJ]

Yeah, I don't recall me melting away when Chernobyl went off, and Bosnia is pretty close to Ukraine. Close enough that the government scrapped the entire year's harvest, IIRC.

[Greiger]

You saying that with your avatar next to it scares me a little.

10000 (out of 17000) missing from one of the towns hardest hit by the tsunami. They showed before/after pics of it, only one building is still standing.
