:banghead: <-- Not directed at you, just the general misinformation about nuclear power
If they aren't near the incident, they definitely won't be effected by the radiation leak.
The US already had a meltdown: 3 mile island. No damage to the people living nearby, hell, there wasn't even a mandatory evacuation because it wasn't an issue. I think radiation levels reached 10000 times normal, but that still was only enough to count as getting an x-ray or two. No damage to the ecosystem in the long-run, no damage to the population, and the only material damage was that the station that melted down was inoperable from then on. They even continued operating the station right next to it.
To exemplify just how silly the fear of civilian nuclear power plants is: The Navy uses nuclear power in countless ships and submarines. Things that get shot at while carrying countless tons of explosive ordinance and conventional fuel. No worries whatsoever.
I guess I was thinking about the nuke tests done on bikini atoll back in 1940's and 1950's. While there's no radiation (as in, nothing about background levels) on the sunk ships anymore, the vegetation on the island still has very high levels, which are, naturally, transmitted to the fruits and other edible materials (which is why the native inhabitants still can't go back there and subsist on local vegetation). I think some of the stones and buildings also have radiation levels. I had watched a documentary about it on some channel or other (Discovery HD or Nat Geo Wild, or Discovery Channel, one of those). So, I know that much of the mess gets "cleaned up" by nature anyway, and I remember reading about how there have been a lot of tech advances in cleaning up radiation (such as from "dirty bombs") quickly . But some stuff lasts longer than others and in particular places, with varying effects (from none to detrimental) depending on the organism. :unsure:
I was also thinking about wind-blown particles - isotopes, like Cesium and Strontium. The Wall Street Journal and other news outlets mention those isotopes as the kind that could get picked up and spread in air currents. The article I read talked about how those isotopes in particular mimic some of the elements our own body uses (like calcium) and thus gets incorporated into the body (as the particles travel up the food chain), and cause detrimental effects. But, the articles did say that those radioactive isotopes get released when there is a total melt-down.
Nuclear power is always a "not in my back yard" thing. And the aging infrastructure of current plants (and the periodic "oops" leaks; there was one last year in vermont or new hampshire, I forget which) don't really help its reputation.
But, yeah, I know that granite emits a lot, more sometimes than whatever the nuclear plant workers are exposed to.
