That would depend on the type of target selected and yield of the bomb used.
The Trinity test explosion fireball was more than 1200 feet in diameter, minor damage was found on a manned bunker 30000 feet from the blast.
The extent of destruction caused by an atomic bomb can vary significantly depending on several factors including the bomb's yield, height of detonation, and surrounding geography. In general, a fairly powerful atomic bomb could potentially cause destruction over an area of several square miles, with severe damage concentrated closer to the detonation point.
Depends on the size of the bomb (they come in many different sizes- bigger is more destructive) and how high the bomb is above ground when it explodes. Most are set to explode when several hundred feet above ground.
The first atomic bomb, dropped on Hiroshima in 1945, leveled approximately 4.7 square miles of the city.
The atomic bomb that was dropped on Hiroshima in 1945 had an explosive yield equivalent to approximately 15 kilotons of TNT. This explosion resulted in massive destruction and loss of life in the city.
from roughly 30,000 feet to detonation at roughly 1500 feet.

The atomic bomb has never been used in Mexico, but it has been used in Japan during World War II. The atomic bomb caused many devastating effects, such as deformities in people and crushing buildings.
