Edit:
Radioactive clouds will not just stop but most likely go a couple of times around the world, anybody old enough who can remember Chernobyl can testify to that.
It would have massive massive impact on the economy which just started to recover.
Never mind the plant and animal life around the area.
It could have a huge impact on anybody
This ain't russia behind the iron curtain everybody wants to fail, this is Japan the second largest economy in the world.
BTW they have just released news that more than likely a major incident happened in one of their reactors, one of worker is seriously sick with uncontrolable vomiting which is radioactive poisoning.
More news says that a major meltdown is either happening right now or has already happened.
I tell you something, this will work out the same as in chernobyl were they witheld information until the end, I say regardless of how the wind is etc , do not walk in rain in the next couple of days.
