Crossroads Able, airdrop over Bikini atoll in summer 1946. This was an airburst effects test of a "stockpile" bomb. It was almost certainly a MK-4 (improved composite core implosion device in a much lighter and easier to assemble casing than the MK-3 Fatman).

detonation of an atomic bomb? I believe it is gamma radiation.Fallout emits large amounts of gamma.It is neutrons.
An atomic bomb is usually dropped from an aircraft before detonation. The bomb is released from the aircraft, allowing it to fall toward the target area where it explodes upon impact with the ground.
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.
In excess of 50,000 meters/second, but the exact velocity depends on yield.
from roughly 30,000 feet to detonation at roughly 1500 feet.
A megaton bomb is more damaging than an atomic bomb because it has a much higher explosive yield. A megaton bomb releases energy equivalent to the detonation of one million tons of TNT, while an atomic bomb typically releases energy equivalent to the detonation of thousands of tons of TNT.
There was no 4th atomic bomb.
The use of the atomic bombs in 1945 did not 'cause the Cold War'.
The first detonation of a nuclear device was the Trinity Detonation on July 16, 1945 35 miles southeast of Socorro, New Mexico
The atomic bomb tested at the Trinity test site in New Mexico during World War II was a plutonium-based implosion-type bomb known as "Gadget." This test marked the first detonation of a nuclear weapon.
The detonation of the bomb seemed fast approaching and inevitable.
