How many nukes does it take to start winter : 100 bombs

One very notable conclusion that was reiterated from the 1983 study was that if oil refineries were the main targets, only 100 bombs would be enough to cause a nuclear winter. Sagan and Turco (one of the 'T's) followed up their second paper by publishing a book: "The Path Where No Man Thought".

How long does nuclear fallout stay in the air : One hour after a surface burst, the radiation from fallout in the crater region is 30 grays per hour (Gy/h). Civilian dose rates in peacetime range from 30 to 100 µGy per year. Fallout radiation decays relatively quickly with time. Most areas become fairly safe for travel and decontamination after three to five weeks.

Could humans survive a nuclear winter

Likelihood of complete human extinction

Many scholars have posited that a global thermonuclear war with Cold War-era stockpiles, or even with the current smaller stockpiles, may lead to human extinction. This position was bolstered when nuclear winter was first conceptualized and modelled in 1983.

According to the 2023 UN State of World Population report, the current world population is 8 billion — detonating about 400 atomic bombs would wipe out humanity, and there would be no life on earth for a long time.You'll only have about fifteen minutes to seek sufficient cover, but radiation will die down to acceptable levels in most of the blast area after just a few days. Note that fallout is at its absolute worst in the first 72 hours, so it's crucial to evacuate immediately or stay sheltered.

How long after a nuke is it safe to go outside : Unless you're told to go outside, it's best to stay put until the risk of contamination has gone down. The US Department of Health and Human Services recommends staying indoors for at least 24 hours after a nuclear explosion.
