It depends upon the size of the fragments. Very small fragments can be blown into the air and carried by air currents around the world.
A gravity dropped nuclear bomb could fall several tens of thousands of feet from bomber to detonation. A ballistic missile's warhead could travel tens of thousands of miles from launch site to detonation.
Around the world several times, getting weaker with distance. This is one way tests can be detected.
A car accelerates from to at a rate of How far does it travel while accelerating
Gamma Rays will travel as long as they have energy
they travel how far they want to
Tiny fragments can travel all the way around the earth from a 1-pound explosion.
Half a Mile
It depends upon the size of the fragments. Very small fragments can be blown into the air and carried by air currents around the world.
It can't go any where it can travel in an aeroplane.
About 1500 miles.
A gravity dropped nuclear bomb could fall several tens of thousands of feet from bomber to detonation. A ballistic missile's warhead could travel tens of thousands of miles from launch site to detonation.
If the enemy is always moving then a smart bomb will have the power to chase down the enemy troop's butt no matter how far they travel, whilst a gravity bomb is just dropped instead of guiding itself into the enemy lands.
Around the world several times, getting weaker with distance. This is one way tests can be detected.
Depending on the material, it will be 1/2 mile CBRNE - 1/2 mile
"Too far to travel for you"
That will depend on the size of the bomb, how far above ground it explodes, and how far away it is from you.
