Isn't a shockwave air pressure traveling faster than the speed of sound, accounting for the over and under pressure waves that physically tear down structures and physically damage internal organs of those exposed to the waves? I'm no scientist, and I ask this fully expecting to be harshly corrected, but I'm trying to go by my current knowledge on the subject, not googling it to look like my pants are smarter than they truly are. Thanks for even reading this, whoever you are. I wish you peace and long life.

Iafiv Iv (1 месяц назад)
Unless you get a warning time of at least 4-5 hours you're dead.Offut is pretty much in the top 5 most important targets in the US.Even a coutry with a relatively small arsenal would likely include Offut on the target list ahead of NYC.As for help afterwards assuming you survived somehow no chance.They'd only send some drones to watch the fires spread and report back just how bad it is.

On a radio you'll want to use one with vacuum tubes or at the very least a simple analog transistorized radio as a digital one will likely get fried. Your best bet to survive would be to get as far from any other valuable target such as a major city or military installation as possible before it happens.

You forgot to mention something important about fallout: IT’S ONLY PRODUCED BY GROUND BURSTS! Air bursts are the preferred method for maximizing destruction in a city, but they produce _no_ fallout. Fallout is dirt particles coated with radioactive material, so the fireball has to touch the ground to produce them, and ground bursts are only going to be used to destroy ICBM missile silos, which are all in Montana, North Dakota and Wyoming.
Zane Shute (1 месяц назад)
yeah you're right, casualties from radiation and its lasting effects weren't a big deal after hiroshima and nagasaki or anything
Iafiv Iv (1 месяц назад)
Zane Shute  They produce some fallout but its acceptable meaning the total increase in the number of of persons with radiation sickness would be too small to be noticed in the general population.
Zane Shute (2 месяца назад)
air bursts still definitely produce fallout, but its just much less severe than ground bursts

I have no intention of surviving a nuclear attack. I'm close enough to one of the four targets in my area to be incinerated and that is my plan. I can't imagine why anyone would want to survive such a thing.

Alex Coleman (3 месяца назад)
Foreshadowing though, better learn up. ;)
Eddy Aruda (3 месяца назад)
Nuclear fallout only occurs with ground strikes which are rarely used. Airbursts destroy more infrastructure and are what would be used unless it was an underground target (e.g missile silo, command and control bunker, etc.) If there is fallout and you are in a basement make sure that there is enough insulation (dirt, cement, steel, etc.) above the cellar and adjoining areas.
Shawn Johnson (3 месяца назад)
I notice one thing she gets wrong is that multi megaton warheads are deployable on missiles or bombers. Except for the Czar Bomba, which at 50 megatons caused serious damage to the bomber that dropped it during the test.
Nicholas Ennos (3 месяца назад)
No need to worry. It is scientifically proven that nuclear bombs are fake. Phillippe Hubert's test for the age of wine showed there was no caesium 137 in the atmosphere before the first nuclear power station accident at Chalk River in 1952. So all nuclear weapons before this date were fake. No doubt all nuclear weapons after this date are fake too.

Olivia, even though you look überhot in black, wearing it during a nuclear attack would likely cause you to burst into flames from the flash, instead of simply boiling pavement into lava in your wake.
Von Faustien (5 месяцев назад)
sure 400kilotons doesn't sound as big as the megaton yelid warheads but most icbms use a mirv system so each missile isn't just going to have one of those it's going to have several so your dealing with a cluster of explosions not just a single large blast. The reason they switched from useing larger yields want weight baring but effectiveness as baring hardened bunkers multiple small explosions do more damage. It's also harder to stop sevral 500 kiloton warheads than one multi megaton yield one.
Joshua Vogel (5 месяцев назад)
wow horrible research done here modern nuclear weapons can easily be 50-250 MT along with MRV's (multiple re-entry vehicles.)
Zane Shute (5 месяцев назад)
Are you sure? The highest yield nuclear weapon in the world at the moment is a 5 MT warhead used on a variant of China's DF-5, one that isn't common and is slated to be retired soon. Opting for multiple lower-yield MIRVs has been the standard for decades. The average yield of a nuclear warhead today is about 443 kilotons.

Jeffman12 (5 месяцев назад)
Should also mention how fallout manages to contaminate things, and why it's deadly. Fallout isn't just ambient radiation, it's irradiated particulate that emits ionizing radiation. If you get some in your food, it can wreak havoc on your internal organs, and is incredibly difficult to pass. Having sealed food sources and good hygiene are a must.

Michael Thompson (5 месяцев назад)
"...too heavy for long-range missiles to carry." Sheesh SciShow please do -some- research? Sub-megaton nuclear devices are used for the sake of efficiency, not necessity. The LGM-25C Titan II warhead was 9 megatons, and "could eventually carry a warhead with a 35 megaton yield, based on projected improvements." https://en.wikipedia.org/wiki/LGM-25C_Titan_II

DeepPastry (6 месяцев назад)
That wasn't the best information. Devices delivered by ICBMs and CBMs are measured in kt; 300 kt to 500 kt max per device in the MRV package. but most "bombs" are measured in Mt; 1.5 Mt. That's just because the modern arsenal doesn't waste so much to empty air. Though the bunker buster nuke bomb is at 25 Mt. For much of the Cold War the average bombs were in the 10 Mt range, small ones in the 2.5 Mt, and big ones near 20 Mt. But we figured you could do more damage by using smaller yields on more bombs/devices using the same amount of material. Oh, and most of these are dial-a-yield variants, where smaller yield means way worse fallout, so you sort of prefer max yield just to keep it "clean" but sometimes it's nice having options.
Zane Shute (5 месяцев назад)
Oh, yeah, the weapons in storage. My bad. I mean the US and China have probably less than 70 deployed total - I know this is true for the US, but for both countries, they're slated to be retired soon. Either way, that's not what they'd use to take out cities. The ballistic missile-mounted warheads would be doing that.
DeepPastry (5 месяцев назад)
650 sounds like a number that is "more" than 70. And that is the number of 1.2 megaton weapons in the current active US Arsenal. I assume the Russians and the Chinese have equivalents.
Zane Shute (5 месяцев назад)
DeepPastry I wouldn't say many. Less than 70 worldwide, probably.
DeepPastry (5 месяцев назад)
Almost no multi-megaton-class weapons exist, because it's pointless and a waste of resources. There are many 1 to 2 megaton devices, though they are dial-a-yield types. That's the size you want to take out fleets, and full sized cities.
Zane Shute (5 месяцев назад)
Close. Almost no megaton-class weapons exist today. US has a couple that are awaiting retirement; China's in the same spot. Warheads atop ballistic missiles today, according to current arsenals, range anywhere from 100 kt to 800 kt. Most are on the lower end of the spectrum to around the middle. You've got the yield/fallout ratio backwards. Generally speaking, the higher the yield, the more fission has to be used, and thus "dirty" variants of thermonuclear weapons offer increased blast yield at the cost of more fallout as well.

How much time before the fallout? If you have just a few minutes, shelter is mandatory. But if you have 10-30 minutes, one could get the car, seal it as best as possible and try to "outrun" the very harmful first waves, couldn't they?
kangourouuu1 (5 месяцев назад)
Well thank you kind sir. That may never be useful to me, but it's always pleasant to understand it a bit better.^^
Zane Shute (5 месяцев назад)
It's pretty much the wind. The mushroom cloud from a nuclear explosion can, depending on the yield, stretch to tens of thousands of feet, and far surpass even where commercial aircraft cruise at. At that height, high atmospheric winds carry the fallout very fast and very far.
kangourouuu1 (5 месяцев назад)
Well, nobody ever told me that, neither when learning the basics nor when learning about more technical stuff. So that's freaking good to know.^^ Thank you. Secondary question then : why does it go that fast? Nobody ever told me about it, but it never naturally occurred to me either, so I'm missing something. Is wind *that* useful for fallout's propagation or is it simply "fast in the medium that is air", however that could make sense?
Zane Shute (5 месяцев назад)
Nah. Fallout travels extremely fast and for hundreds of miles. Cars offer virtually no protection against fallout particulates. Best to shelter in place.

Tornado sirens went off in my area a few days ago, and literally the only thing that came to mind when I heard them was, "Oh... I guess that means we're about to be nuked in a few seconds. Oh well. I figured it was going to happen anyway." Tornados weren't even a thought in my mind when I heard the sirens, because it was only breezy outside. I just kind of immediately accepted that my life and the lives of my cats, my fish, and my parents were going to end in just moments.

It's foolish to think you can out right block gamma rays, you can reduce exposure, but that's it. The more material between you and the fallout/initial blast the better.
Jcewazhere (6 месяцев назад)
So most if not all of the radiation is in the leftover bits of uranium that didn't undergo fission, and the fallout, not in the blast wave? In other words watching a nuke could blind you from the photons and cook you with the heat but not immediately kill you with radiation?
