What should you do if you are near a nuclear blast?
If warned of an imminent attack, immediately get inside the nearest building and move away from windows. This will help provide protection from the blast, heat, and radiation of the detonation.
How far away from a nuclear blast is safe?
Death is highly likely and radiation poisoning is almost certain if one is caught in the open with no terrain or building masking effects within a radius of 0–3 km from a 1 megaton airburst, and the 50\% chance of death from the blast extends out to ~8 km from the same 1 megaton atmospheric explosion.
How close to a nuclear bomb Do you need to be to go underground?
Preparation. The test site is carefully geologically surveyed to ensure suitability. Such tests usually take place well away from population centres. The nuclear device is placed into a drilled hole or tunnel usually between 200-800m (650-2,600ft) below the surface, and several metres wide.
Does the president have sole authority to launch nuclear weapons?

How far away from a nuclear bomb would you be blind?

How far away from a nuclear explosion can you be?
The blast area of destruction is only 5-7 miles from any nuclear target, so don’t prepare against blast effects, which is very expensive—relocate instead. Avert your eyes immediately from even a distant explosion and duck behind anything that will shield you from the instantaneous line of sight radiation and intense heat and light.
Could a US city be hit by a nuclear bomb?
The chance that a nuclear bomb would strike a US city is slim, but nuclear experts say it’s not out of the question. A nuclear attack in a large metropolitan area is one of the 15 disaster scenarios for which the US Federal Emergency Management Agency has an emergency strategy.
Does America have an adequate nuclear detonation plan?
“There isn’t a single jurisdiction in America that has anything approaching an adequate plan to deal with a nuclear detonation,” he said. That includes the six urban areas that Redlener thinks are the most likely targets of a nuclear attack: New York, Chicago, Houston, Los Angeles, San Francisco, and Washington, DC.
