more than 20 miles and you would still get burned
Yes, if he's far enough away, or behind a lead shield and, still far enough away.
The visibility of a nuclear explosion depends on various factors such as the size of the explosion, weather conditions, and the observer's distance from the blast. Generally, a nuclear explosion can be seen from tens to hundreds of miles away, depending on these factors.
Stay indoors, as far from the outside as possible.
No. A lahar carries far less power than a nuclear bomb. However, large explosive eruptions, which can lead to lahars, can be as strong as or stronger than a nuclear explosion.
Uranium can be exhausted by using this metal as a nuclear fuel.But we are still far from it.
The destructive radius of a five-kiloton nuclear explosion is typically around 500 to 700 meters, resulting in significant destruction of buildings and infrastructure in the immediate vicinity of the blast. This radius can vary depending on factors such as the height of the explosion, terrain, and weather conditions. However, it's important to note that the effects of a nuclear explosion extend far beyond the immediate blast radius due to factors like heat, radiation, and fallout.
The vast majority of bacteria live far far underground, in rock.
That would depend on several variables in very complicated ways:yieldburst height/depthconstruction of targetif subsurface, material at burst depthwindweatheretc.
Nowhere as far as I can find. Perhaps you are thinking of the 1986 Chernobyl steam explosion and graphite fire. This was in the USSR and although the graphite fire melted much of the core, it was not a meltdown in the usual sense associated with nuclear reactors.
No, surviving a nuclear explosion by hiding in a fridge like in the movie "Indiana Jones and the Kingdom of the Crystal Skull" is not realistic. The impact and heat from a nuclear explosion would be far too extreme for a refrigerator to provide any protection. It's best to follow official safety guidelines for nuclear emergencies.
The American ships were approximately 12 miles (19 kilometers) away from Hiroshima when the atomic bomb was dropped on August 6, 1945. Despite this distance, some crew members on those ships still experienced the impact and witnessed the devastating effects of the explosion.
No because the explosion is catastrophic and you'd need somewhere to store all of that energy. For power generation you need something that is continuous. far better to trap the gravitational energy of a black hole, or a neutron star.
