If a nuclear bomb went off in Iran, how long would it take for the effects of the explosions to reach the U.S.

Answer 1

It takes 5 five days for air to travel around the world, so probably a couple of days. The real question is how long will it stay? Radioactive particles from Chernobyl are still over Brittain, decades after the 'meltdown'.

Answer 2

There will not be as big of a hole in the ground as you may think. When the reaction starts it catches the air on fire and flashes pushing everything away from it. This will burn or melt most every thing close by and the pushing wind will blow down most everything for miles and miles taking along a good dose of radiation to kill anything that lived past the blast and the 600 MPH winds. Then there will be a back lash kinda like an implosion of the air and fire going back after the explosion is over and will finish off anything standing or living that the explosion missed. This will not affect anything on this side of the world unless the wind blows the radiation here. But no worries, We will not use a nuke on Iran because we would kill people in every country around them. We will take them out the same way we did Iraq. So get ready to open your wallet and pay to rebuild Iran.

Answer 3

Although I know it wasn't exactly what you were asking, I'd say we'd start feeling effects in about an hour. Namely, if any country started using nuclear bombs against another country right now, I fully believe that every country with nuclear power would pick a side to join up with and start firing. The devastation to the planet (including the United States) would probably destroy most life (Including several billion people), leaving maybe a billion people world-wide still alive. We would feel these effects just like every other part of the world, the only difference would be that we would be launching more bombs than other countries. At the same time, many of the dozens of countries who hate us would be launching bombs at us, and in essence we would destroy each other.

Answer 4

It depends on the purity of the resources used to make the bomb, the type of bomb, and how big the bomb is.

Personally, I doubt we'd feel anything, and neither would most of Iran except for ground zero and the surrounded area. (It's a large area, but it won't tear the entire country apart.)

Answer 5

Well, Iran is very very far away. If the bomb was the same size as the one used in Hiroshima, we would not be able to tell by casual observation; we would need to look for effects with sensitive instruments.

Answer 6

it really depends on the size of the bomb. but i think it would be 5 days to two weeks
