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.
Stay indoors, as far from the outside as possible.
You can only hope that you live very far from Java.
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.
You can survive a nuclear explosion if you are far enough away from it for the initial heat and blast to have little or no effect on you. You then need to be deep enough underground or in a well-built shelter to avoid the radioactive fallout that would occur for days and weeks after the explosion. If you are far enough away, deep enough into a shelter, and have enough food, water, sanitation, medicine and luck, you would survive. To what end, who knows? But you'd be alive.
That would depend on several variables in very complicated ways:yieldburst height/depthconstruction of targetif subsurface, material at burst depthwindweatheretc.
Uranium can be exhausted by using this metal as a nuclear fuel.But we are still far from it.
The vast majority of bacteria live far far underground, in rock.
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.
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.
they travel how far they want to
