Actually not long, but it depends on the level and type of contamination.
Most urban areas can be reoccupied in a few days to at most about 4 months. The radioactivity will have to be periodically measured with ionization type radiation survey meters (geiger counters can't be used for this) to determine when it become low enough to be safe.
Areas that were hit with surface or subsurface bursts (e.g. missile silos, airfields) may be so heavily contaminated that they cannot be reoccupied for years to centuries.
These periods of time can be shortened by various decontamination techniques, but this can get very expensive compared to just waiting for the various radioisotopes to decay.
Yes, not only radioactivity but the fuel must be fissile. If we happened to live on a much older earth, both nuclear reactors and nuclear bombs would be impossible as the Uranium 235 isotope would have decayed to only trace levels. If we happened to live on a much younger earth, nuclear reactors would occur naturally and spontaneously and you might see radioactive geysers erupting from them near where you live.
Nuclear reactions can be both good and bad. They can produce clean energy, like in nuclear power plants, but also be used to create nuclear weapons which have destructive capabilities. The key is in how nuclear reactions are managed and controlled.
There is no guaranteed safe state during a nuclear attack, as factors such as proximity to potential targets, wind patterns, and shelter availability all play a role in determining safety. However, states with lower population densities and less strategic importance may be at lower risk. It's important to follow emergency preparedness guidelines and have a plan in place regardless of where you live.
Available plutonium and uranium are reserved for nuclear weapons is not a factor in why nuclear energy has failed to live up to the hopes that it would solve the nations' energy needed. Many people worry about the safety of nuclear reactors.
People may not want to live near nuclear power stations due to concerns about safety and the risk of accidents, such as meltdowns or radiation leaks. Additionally, there is a perception that living near a nuclear power station could harm property values and potentially pose long-term health risks.
If that was the only place and you were not there... well, the rest of your normal life span.
That depends mostly on where you are relative to the burst.
This means you either have cancer of your nuts or you live in a nuclear bomb testing area!
The badlands is a place where the fringes people, when sterilised are sent to, to live apart from the people of Waknuk. In the time of the Old People, a nuclear bomb was dropped on what is now known as the Badlands, causing the land to become infertile. Nothing that is the norm of Waknuk can grow in the Badlands because this bomb was dropped.
Certain types of bacteria, maybe. Especially the ones that live deep in the crust.

Where you used to live before your current place.
Are You for real- who wants a bomb scare in a live theatre? You may be thinking of the educational or scientific cartoon ( factual, not sci-fi) called The Big World of Little Atom, which as the title suggests- may have had explanatory stuff on nuclear arms/
earthquake, tsunami, nuclear radiant, sound polution, water polution
Bend over, put your head between your knees, and kiss your you know what goodbye. Edit: (What I would do) Most likely move to Russia with most of my wealth and buy a house and live my life there because Russia is too big of a land to destroy and not to forget is the national with the most superiors in a nuclear war. Or I could build a bunker that can stand a Nuclear bomb like in Nuketown OR hide in a fridge like Indiana Jones (and the tomb raiders) did before the nuke went off!
Yes it is a very nice place to live :) but only if you like hot humid weather but ive lived there before its awesome the best place i ever lived.
Cockroaches live anywhere and everywhere. They are the longest surviving species and eat anything. They will outlive humans. they live at the dinosaur age they can survive a atomic bomb
