How long would it take for Earth to be habitable after a nuclear war?
Probably about 5-10 years minimum.
What would the aftermath of a nuclear war look like?
Besides the immediate destruction of cities by nuclear blasts, the potential aftermath of a nuclear war could involve firestorms, a nuclear winter, widespread radiation sickness from fallout, and/or the temporary (if not permanent) loss of much modern technology due to electromagnetic pulses.
How long until it is safe after a nuclear bomb?
Most areas become fairly safe for travel and decontamination after three to five weeks.
How long does it take for nuclear radiation to dissipate?
Seven hours after a nuclear explosion, residual radioactivity will have decreased to about 10 percent of its amount at 1 hour, and after another 48 hours it will have decreased to 1 percent.
What would happen if we all got nukes?
radiation from standard nukes would hang around for a hundred thousand years and continue to be a limiting factor in our resurgence as the dominant life form on the planet. The nuclear winter from the explosives themselves could go a few to several growing seasons, causing instant food shortages.
How long will nuclear winter last?
The Pentagon determined that Nuclear Winter could last upwards of 100 years but most probably would last less than 50.
Why did it take so long to rebuild Nagasaki?
Photographer Shunkichi Kikuchi impressively documented the reconstruction process of the city and created panoramas of its restoration two years after the bombing. The restoration of Nagasaki was slower due to financial difficulties and did not start until 1946.
How long does it take to decontaminate after radiation exposure?
The overall radiation would be relatively safe after two weeks, this means that after two weeks you can go out to get food and water rations for a limited amount of time and it is safe enough for people wearing protective clothing to start decontamination.
