* Yield: The size and power of the bomb (its yield, measured in kilotons or megatons of TNT) is the primary factor. A small tactical nuke will have a much smaller blast radius than a large strategic bomb.
* Type of Detonation: Air bursts (where the bomb explodes above ground) have different effects than ground bursts (where the bomb explodes on or near the ground).
* Terrain: The surrounding environment affects the blast. A bomb detonated in a valley will have a different impact than one detonated on a flat plain.
Instead of a single number, here are some general points:
* Fireball: The initial fireball created by the explosion can rise thousands of feet into the air.
* Blast Wave: The shockwave from the explosion can travel many miles, causing damage and destruction over a wide area.
* Mushroom Cloud: The iconic mushroom cloud is a result of the rising fireball and the heated air. It can rise tens of thousands of feet, and its size depends on the bomb's yield.
To understand the specific effects of a given atomic bomb, you need to consider its yield, detonation type, and the surrounding environment.
