What’s the difference between an atomic bomb and a nuclear bomb?
Both atomic bombs and hydrogen bombs are kinds of nuclear bombs, meaning that the energy comes from nuclear reactions. … The big difference is that atomic bombs use nuclear fission, which splits a bigger atom into two smaller ones, to create their energy.
Can a nuclear bomb destroy a whole city?
A nuclear device no larger than traditional bombs can devastate an entire city by blast, fire, and radiation. … Since the atomic bombings of Hiroshima and Nagasaki, nuclear weapons have been detonated over two thousand times for testing and demonstration.
Can we survive a nuclear war?
A government safety expert says it’s entirely possible to survive a nuclear explosion and its aftereffects. The prospects for survival are even better if there are several minutes of warning, something Hawaii’s ballistic-missile-threat system can provide.
How long would radiation from a nuclear war last?
1 to 5 yearsFor the survivors of a nuclear war, this lingering radiation hazard could represent a grave threat for as long as 1 to 5 years after the attack. Predictions of the amount and levels of the radioactive fallout are difficult because of several factors.
Is Hiroshima still radioactive?
Among some there is the unfounded fear that Hiroshima and Nagasaki are still radioactive; in reality, this is not true. Following a nuclear explosion, there are two forms of residual radioactivity. The first is the fallout of the nuclear material and fission products.

How far can a nuclear explosion go?
Death is highly likely and radiation poisoning is almost certain if one is caught in the open with no terrain or building masking effects within a radius of 0–3 km from a 1 megaton airburst, and the 50% chance of death from the blast extends out to ~8 km from the same 1 megaton atmospheric explosion.
