There are too many factors to give you one simple answer. It will depend on the yield (size) of the weapon, where it is detonated (on ground, low airburst, high airburst) etc. A 150 kiloton weapon, low airburst, would cause 3rd degree burns at about 5.4 kilometers, and cause total destruction of ordinary buildings (from blast) out to 4 kilometers. Current day nuclear weapon are LESS powerful than the VERY large weapons from the 50s and 60s- better guidance systems can place the weapon on target within a matter of feet- in the 1960s, it was a matter of miles.

How far can a nuclear blast from an a-bomb travel?

Around the world several times, getting weaker with distance. This is one way tests can be detected.


What is the difference between a conventional bomb and an atomic bomb?

A standard bomb relies on the explosive power of chemical energy, like TNT for example. The size of the blast will depend on the amount of explosives packed into the bomb. After the blast, there will be the "usual" damage, which will be proportionate to the size of the bomb. Destruction and casualties will present as they always have from the blast of a weapon. With a nuclear weapon, the energy is derived from the nuclei of atoms (using either fission or fusion). It is nuclear energy, and nuclear weapons are, by tapping into this type of energy, able to deliver a much larger blast and broader blast effects than conventional weapons. The blast can be thousands or millions of times more devastating than any conventional bomb blast. And in addition to killing in the way chemical explosives do, it can also severely burn and can irradiate victims, and they can die weeks, months or even years after surviving the initial blast. There is also the element of nuclear "residue" from the nuclear blast. Radioactive contaminants will be found on the ground and in the air. And the airborne ones will circulate according to local weather patterns. This will create what is called fallout, and the radioactive materials can be deposited many miles from ground zero. This ends up creating health damaging effects far from the site of the blast.


What is the blast radius of a nuclear weapon?

That depends on what you're referring to: The fireball radius (the nuclear explosion itself), the total anhiliation range radius, and etc. For example, the bomb launched on Hiroshima had a fireball of several hundred feet in radius, a 1km total destruction range radius, and severe damage for miles. For firepower bombs (nuclear bombs made for power show & not effectiveness) The Tsar bomba of USSR had 50~55 megatons of TNT firepower, a fireball with 1km+ radius, total destruction for miles, and created a sound shockwave that could be heard in Norway/Other far Northern European areas. Modern nuclear weapons don't have a single blast radius; the U.S. developed M.I.R.V.s (cluster nuclear bombs) that spread apart to create a shotgun blast of multiple nuclear explosions.


What is the surprising effect of the neutron bomb?

A neutron bomb, or enhanced radiation weapon (ERW), is a type of tactical nuclear weapon designed specifically to release a large portion of its energy as energetic neutron radiation rather than explosive energy. Neutron bomb would use nuclear fusion, but in a different way. The detonation of a neutron bomb would still produce an explosion, but one much smaller than a standard nuclear weapon's. The main effect of a neutron bomb would be the release of high-energy neutrons that would take lives far beyond the blast area. The result: fewer buildings, cars, tanks, roads, highways and other structures destroyed.


How far can nuclear missile travel?

Depends on how it is transported. There are different types of missiles with different ranges. Also you can carry nuclear bombs on airplanes, so literally everywhere in that case.

How far US nuclear weapon to russia?

About as far as a US airliner to Russia. They will follow about the same ground track.


Can nukes travel all over the whole entire World?

The answer is yes, some nukes can travel all over the World and can travel really far. The most modern nuclear weapon delivery systems, the intercontinental and submarine-launched ballistic missiles, can plausibly deliver a weapon anywhere in the world. A nuke cannot, however, fly around like a jet.

Why are nuclear weapons so bad?

They can blow up earth.Think about Herishima.Similar thing will going to happen if the nuclear weapons are usedNo one has built or will build a nuclear weapon or enough nuclear weapons to "blow up the earth", it would have no military value. However the collateral damage in fallout from any major attack would likely kill far more people than the attack itself, and those results are unpredictable.


What is a nuclear fallout?

When a nuclear weapon explodes above ground there is a great upsurge in air currents because of the heat released-you will have seen pictures of the 'mushroom' cloud no doubt. This carries the fission products formed by the nuclear explosive, and also a lot of dust and debris some of which will have been made active by the huge burst of neutrons released in the explosion. This cloud is carried up so far and then falls to earth-this is the nuclear fall out. The prevailing wind will determine which way the plume goes, and how far.
