Atomic Bomb |
||||||
 |
||||||
|
||||||
| When an atomic bomb explodes, a fireball creates shock and heat waves that destroy structures in the immediate vicinity of the blast. The rising fireball sucks up debris to form a mushroom cloud. Damage can occur over large distances. For example, the radius for severe damage could be approximately 18 km (11 mi) for a 10-megaton blast. Radioactive fallout may be dispersed worldwide through global atmospheric processes. | ||||||
