The visual effects of a high-altitude or space-based explosion may last longer than atmospheric tests, sometimes in excess of 30 minutes. Heat from the Bluegill Triple Prime shot, at an altitude of 50 kilometers (31 miles), was felt by personnel on the ground at Johnston Atoll , and this test caused retina burns to two personnel at ground zero ...
Overpressure in an enclosed space is determined using "Weibull's formula": [5] [6] = where: 22.5 is a constant based on experimentation = (kilograms) net explosive mass calculated using all explosive materials and their relative effectiveness
The pitch angle (the angle between the direction of the motion of the particle and direction of the field line) has a low value at the equator and increases while the particle moves down a field line in the direction where the magnetic field strength increases. When the pitch angle becomes 90 degrees, the particle must move in the other ...
Now new research claims to have shown that the explosion is in fact a nearly perfect sphere, and is completely symmetrical. Scientists have pursued a number of possible explanations – such as ...
The single-most important thing to remember if a nuclear bomb is supposed to explode, he says, is to shelter in place. "There were survivors in Hiroshima within 300 meters of the epicenter ...
In July 1962, the US carried out the Starfish Prime test, exploding a 1.44 Mt (6.0 PJ) bomb 400 kilometres (250 mi; 1,300,000 ft) above the mid-Pacific Ocean.This demonstrated that the effects of a high-altitude nuclear explosion were much larger than had been previously calculated.
1.4 Mt (5.9 PJ) The flash created by the explosion as seen through heavy cloud cover from Honolulu , 900 miles (1,450 km) away Starfish Prime was a high-altitude nuclear test conducted by the United States, a joint effort of the Atomic Energy Commission (AEC) and the Defense Atomic Support Agency .
Developed between 1956 and 1961 as the Soviet Union engaged in a nuclear arms race with the United States, the Tsar Bomba - the King of Bombs - was the largest hydrogen bomb ever and was claimed ...
