If a nuclear bomb hit...?

It would depend on the yield (megatons) and altitude at which it was detonated. Then there would be the fallout which depends on wind and weather conditions.

iraq51

Depends on the yield...2kt to 50mt. Is it an air burst (at what altitude) or a ground burst event. By effect are you asking about the blast effect, the effect of radiation or the effect the fires and collapsing build will cause.

And does your question include the Neutron Bomb?

scruffy

Depends on the size of the bomb and exactly what you mean by 'affected'.

regerugged

It depends on the type, Atomic or Hydrogen, and depends on the size of the bomb. Further, it depends if it goes off on the ground or above ground.

nitr0bike

It depends on the strength of the warhead, and how high above the earth it is detonated.
Here is a website to calculate the radius based on explosive power of the device.

Other factors are important, but this gives a good basic view.

turboweegie

Depends upon the warhead size.

Nuclear weapons range in power quite a bit.

Here's a little workup on a 1 Megaton bomb (equivalent to 1 million tons of TNT exploding) and a 25 Megaton bomb: http://www.pbs.org/wgbh/amex/bomb/sfeature/blastmap.html

There's no simple answer. Ground blast or air blast? Weather and terrain? Blast effects, thermal effects, or radiation effects? Immediate or long-term effects? And how much bomb are you talking about? There's a little difference between a 10 kiloton ground blast and a 25 megaton air blast.

dont worry
you will be
dust like everybody else!

Its not me Its u

The following site gives you an idea of the effect of a nuclear detonation on several cities in the US, you can pick the kiloton yield and whether its a ground-level or air burst:

Depends on the strength of the bomb, determines blast radius. The secondary damage is done by sound, heat and radiation. The radiation is especially virulent.
Suffice, you don't want to be in or near the country where that nuke is exploded.

Glynn D

It depends on the size of the bomb. It could be from < 1mile to over 120 miles. That is just the initial blast. If you add in the radiation cloud then it could be several hundred to a thousand miles.

Glynn

depends how powerful the bomb is. today we have nukes that could take out entire states, but like back in the 40's the most powerful nukes only destroyed around 5-10 square miles.
but yeah if a country launched a nuke at the U.S. george bush would prolly launch all of our nukes at every other country in world....

comtnman2003

Depends on the Megatons on the bomb, some are small tacticals that will take care of a city block or two. And others are city levelers that have blast radiuses up into 30-50 miles from ground zero. Of course the damage lessens as you get further from ground zero.

May

The blast would range from about 10-75 miles.

The radiation would be the worst side effect of the bomb, because the radiation can travel hundreds of miles and effect other cities and towns around it.

Garret Tripp

It is typical in military terms to hear of a weapons effectiveness "Radius of Destruction". Have you tried this in a search engine for the most accurate information on different devices which may be used?

Information on the range of travel by projection of such weapons may also be found the same way. Are you aware of the range of weaponry that is available?

everything you could ever want to know is here.

bujiboy

depends on the bomb, but i do not want to be even remotely close

Jim

1000's plus If you are in a place that is hit by a nuclear weapon the "fallout" will kill thousands

puffalump

I think it is usually about 30-50 miles away. Not everything would blow up. But there would be birth deffects and toxins ect.

Lionel M

at least 100 kilometer radius
