How long does a nuclear bomb take to?

Calculations demonstrate that one megaton of fission, typical of a two-megaton H-bomb, will create enough beta radiation to blackout an area 400 kilometres (250 mi) across for five minutes. Careful selection of the burst altitudes and locations can produce an extremely effective radar-blanking effect.

How long does a nuke take to drop?

Nuclear explosions loft this material high into the atmosphere as dust-, salt-, and sand-size particles, and it can take up to 15 minutes to fall to the ground. High-altitude winds can make it sprinkle over hundreds of square miles, though it's most intense near the blast site.

Can you survive a nuke in a pool?

While the radiation from the initial detonation is setting everything nearby on fire, the surface of the water will harmlessly evaporate. Since the boiling point of water isn't very high and the flash doesn't last very long, the whole body of water will stay cool, even if it's only a swimming pool.

What if a nuke hits NYC?

According to Outrider, “the fireball forms immediately from the burning bomb residue, and it emits an enormous amount of energy as x-rays, light, and heat, expanding out as it cools. Anything—or anyone—inside the fireball would be vaporized in an instant.” Since Manhattan is so close, you probably won't survive.

Can a submarine survive a nuclear bomb?

Most current submarines can survive at a depth of 400 m, so they might survive long pressure spikes created by the waves above them as high as 200–400 m, but not kilometer size waves. Submarines are also designed to withstand short pressure spikes from close explosions of deep charges and even nuclear explosions.
