I read. something about how the nuclear fallout from a blast only lasts around 2 weeks, then it is safe to go outside. Not sure if that's true, but it came from a pretty renown scientist if I remember correctly.
Every radioactive isotope has a different half life, which is how much time it takes for half of a given sample to undergo decay (this decay is what emits nuclear radiation). Some isotopes have a half life of a few nanoseconds, others like Uranium-238 have a half life of several billion years.
What isotopes a nuke creates depends on what elements are in the material that make up the bomb and the immediate environment, as these atoms are going to be made radioactive by the detonation. You’re likely going to have somewhat random samplings of most isotopes in existence. I have no data to back this on, but 2 weeks sounds like a ball park estimate for the most radioactive isotopes with the shortest half lives to decay away into irrelevant amounts. If you can minimize your exposure to fallout in this time period, you’ll maximize your chances of survival.

It is likely that the fallout is still hanging around after 2 weeks but is at safe levels to go outside. Has something to do with the half-life of radioactive elements if I am remembering correctly

That’s why you take your Potassium Iodide for 2 weeks, by the end of those two weeks the fall out will have decayed enough to be ‘safe’

2 weeks to flatten the cloud
Underrated comment.
Kek. 😁😂
Jrod, dis you?
Ehem...
