It’s there, near the blast zone. Everything will be irradiated. Everything.
People act like this will be survivable. It isn’t, not with current nuclear weapons. If the blast and shock wave don’t kill you, the radiation will. Or if you were lucky enough to be in a bunker, and you don’t have enough food and water, you will starve before it’s safe to leave.
The best case scenario is to die instantly in the blast. Second best is a bullet before your body literally falls apart from radiation poisoning.
