If a nuclear bomb hit...?

Question

What is the range of a nuclear bomb. I mean if It hits one place how many miles would be effected by it?

Answer 1

approx 25 sq miles

Answer 2

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.

THERE ARE MANY FACTORS TO YOUR ANSWER. HOW BIG IS THE BOMB, WHERE IT'S PLACED, WHICH WAY THE WIND BLOWS, ETC.

The Atomic Bombings of Hiroshima and Nagasaki involved a nuclear attack on the Japanese city of Hiroshima by the United States of America on August 6, 1945 with the nuclear weapon "Little Boy," followed three days later by the detonation of the "Fat Man" bomb over Nagasaki during World War II against the Empire of Japan, part of the opposing Axis Powers alliance.

In estimating the death toll from the attacks, there are several factors that make it difficult to arrive at reliable figures: inadequacies in the records given the confusion of the times, the many victims who died months or years after the bombing as a result of radiation exposure, and the pressure to either exaggerate or minimize the numbers, depending upon political agenda. That said, it is estimated that as many as 140,000 had died in Hiroshima by the bomb and its associated effects,[1][2][3] with the estimate for Nagasaki roughly 74,000.[4] In both cities, the overwhelming majority of the deaths were those of civilians.

The role of the bombings in Japan's surrender, as well as the effects and justification of them, have been subject to much debate. In the U.S., the prevailing view is that the bombings ended the war months sooner than would otherwise have been the case, saving many lives that would have been lost on both sides if the planned invasion of Japan had taken place.[5] In much of the rest of the world, the prevailing view is that the bombings were unnecessary, and that knowingly inflicting harm of this magnitude on civilians was inherently immoral.[6]

On August 15, 1945 Japan announced its surrender to the Allied Powers, signing the Instrument of Surrender on September 2 which officially ended World War II.

TODAYS ATOM BOMBS ARE MUCH MORE POWERFUL.

Answer 4

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.

Answer 5

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.

Answer 6

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?

Answer 7

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

Answer 8

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....

Answer 9

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.

Answer 10

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:

Answer 11

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.
