For most immediate effects (e.g. blast, thermal flash, prompt radiation) the range of the effect is directly proportional to the cubed root of the yield. For other effects (e.g. fallout) the range is less predictable.
so far only two atom bomb were used,both on japan. the first on hiroshima japan aug 6th 1945
depends on how far away you are from where it exploded.
So far in human history only Hiroshima and Nagasaki were ever bombed by a atom bomb.
All bombs are dangerous, but the atom bomb is certainly one of the most devastating. The only type of bomb thus far created that is more powerful than an atom bomb is a hydrogen bomb, which is the type of nuclear bomb that uses fusion instead of just fission. The Tsar Bomba, which is the single most powerful deviceever used, let alone bomb, is an example of a hydrogen bomb. Its yield was rated at a staggering 56 megatons of force. I've added a link below if you'd like more information.
Absolutely, in a fission bomb the fission products are far more radioactive than the original Uranium and/or Plutonium was. Also in either fission or fusion bombs neutron activation converts stable isotopes to radioactive ones.
Enola Gay was flying at 31,060 feet and Little boy exploted 1,900 feet above the city.
That will depend on the size of the bomb, how far above ground it explodes, and how far away it is from you.
None, the airplane had already been far away when the bomb detonated.
no unless if you drop it down a hole that goes straight to the atom clasher in France and at the exact same time that they were clashing the atoms but that is impossible because it is so far down and so protected that it is impossible to get in unless your a scientist working for the atom clasher people.
Not as far as we know.
Never, as far as we know.
Not at all; the cesium atom is far bigger than the lithium atom.
