Of course you were. US Military personal right now are being taught it as a way to survive a nuclear explosion. This is the best possible advice to adhere to as a way to survive a nuclear explosion.
We’ve already established all that.
The question was whether anybody was told that “all we have to do in case of a nuclear explosion was jump under our desk and put our jackets over our heads and everything would be a.o.k.”
Those are two completely different subjects.
For example, do you understand why children are taught “Don’t smoke if you don’t want to get cancer?” Do you agree that this is sound advice to give to children?
Do you see why it would be astonishing if a child were to claim that they were taught "“all we have to do to never get cancer cancer is not to smoke”?
Oh no, hundreds of million of people are taught that you ducked after the detonation. Military personnel are still being taught this. It’s excellent advice.
What people like Triskadecamus apparently don’t understand is that a nuclear “explosion” doesn’t occur instantaneously. There is the initial detonation which releases a bright flash of light that is visible even indoors on a bright sunny day. If you are close enough to be killed during that initial flash, then you have been literally vapourised.
However the radiation released then *continues *to heat the atmosphere for 2 minutes after that initial detonation. For a ground burst the firebal may not even reach it’s maximum extent at ground level for over 8 seconds after the initial flash. This isn’t the pressure wave blast, it’s the fireball, the actual physical explosion. So it’s perfectly possible to be close enough to see the flash, telephone someone to say that you have seen it, and still be completely vapourised by the explosion several seconds later.
More importantly, EM radiation capable of causing third degree burns will be emitted for a full two minutes after the initial flash is seen. The idea behind duck-and-cover is in large part to avoid exposure to the ongoing radiation emission. If you are several kilometres from the detonation point, the radiation emissions will cause second-degree. and may even cause third degree, burns if you are unfortunate enough to expose it to your bare skin for the full 2 minutes. Basically ultra-severe sunburn. However, as with sunburn, the effects can be stopped entirely by thin cloth. The simple technique of pulling a jacket over one’s face will mean the difference between death or permanent scarring and walking away no injury whatsoever.
The other issue is gazing at the fireball. The fireball produces large amounts of UV radiation as well as visible light, and it is an impressive sight, which causes people to stare at it. Unfortunately looking directly at the fireball for more than a fraction of a second, especially during the first 10 seconds after detonation, can cause flash blindness as the retinas get burned. This can be either temporary or permanent, but in the aftermath of a nuclear exchange, even temporary blindness is to be avoided. Even at distances so far removed from the detonation that a person standing in an exposed field will suffer little more than sunburn and a few scratches from flying debris, the same person can be permanently blinded if they watched the explosion for the first 10 seconds.
Then there is of course the issue of flying debris that SenorBeef has already addressed.
So yes, if you see a nuclear detonation, *that *is the time to duck and cover as much of your exposed skin as you can. While the flash itself travels at the speed of light, the radiation continues to be emitted for two minutes after the flash. The blast likewise will take several seconds to arrive. During those first two minutes, it is critical to stay down and stay covered up.
What is kind of sad is that after 50 years, it is still seen as trendy to laugh at this advice, invariably by people who don’t actually understand the facts behind it.
