I'm curious why the mouth needs to be open. Probably to somehow avoid your lungs taking damage from the pressure wave?
ears/hearing
Probably from the blast wave? FEMA's most recent advice doesn't say anything about keeping your mouth open: https://www.ready.gov/sites/default/files/2024-03/ready.gov_nuclear-explosion-hazard-info-sheet.pdf
If you’re close enough to the impact to see the mushroom cloud, the only choice you get is if you want to die instantly or after a week or so.
(Not a physicist or a physician.)
Meh, Richard Feynman wrote in his biography that he saw the first mushroom cloud through a car windshield during the Manhattan project, he lived for another 40-50 years.
He was pretty far away, and that was a small bomb
Still close enough to see the mushroom cloud.
Fallout is highly variable, you absolutely can live. The blast wave is a bigger threat.
A bigger immediate threat, but not the bigger threat. If you survive the initial blast and flash, fallout is almost certainly the biggest thing any survivors will be dealing with, outside of plenty of fires that WILL be started just by the light and radiation.
At least as far as overtly deadly things. Of course what ever has been blown up won't be helping, but it won't actively hurt like fallout or fires will.
I’m no way an expert, but was just reading about the “downwinders” still fighting for compensation regarding the Manhattan project. If you are close, you are done, but if you are far enough, your exposure depends on wind direction/strength
Yea, the wind can definitely push fallout around. Though if you even have to worry about it, you've survived the blast. A shockwave you can see coming is going to have to nail you pretty hard to kill you. Of course a nuke can do that, but it's also putting out insane amounts of light. If you're openly vulnerable to the shockwave before you can react, chances are you're already fried from the light.
If you keep the radioactive particulate out of your water you should be okay indoors
I guess it’s for the pressure difference? If you have your mouth open, your lungs expand and contract together with the pressure difference because of the explosion.
Yes, paper bag syndrome: https://codehealth.io/library/article-67/tension-pneumothorax/
