Could Japan's meltdown affect the planet?

[Del-Toro]

The only thing I'm worried about, from a global perspective, is how this will affect water. Think about it. Chernobyl was fairly landlocked, but Japan is right there in ocean currents. Is it possible we could get irradiated ocean systems? Ok, more radiation in the ocean systems, I'm sure my point is clear.

As in my post above yours, Japan got atomic bombs dropped on them and that contains significantly more radiation which made it's way into the water. Also during the cold war, Nukes were tested on islands and such so that got in the water and air as well.

Not trying to be an ass and if I came off as one, I apologies.

You only sort of did. But you're right. At least if the leak or meltdown doesn't last for very long. I'm a little bit curious as to the effects of sustained radiation (if that's even a possibility here). Fingers crossed it doesn't get there though. Not making any speculations about what would happen then, but I'm sure it can't be good. I mean, Japan was still marginally feeling the effects of little boy and fat man and those were blink and you miss it blasts.

And this is all coming from somebody who's pro-nuclear, but who isn't intimately familiar with nuclear systems.
