Probably because they don't know where to take cover.
Depending on how much time I have, if I had to take cover, I'd either load up supplies in the car and head to the 3rd underground floor of my office parking garage (but away from the vent stacks in 2 corners of the garage), or if I have less time, I'll jump the fence at the apartment complex next door and hide out in their one floor underground garage.
I live in a wood-framed house, so it's going to provide less protection than an underground garage, though still better than running around the streets.
Business insider says 37 minutes from North Korea to Honolulu. I imagine it’s only a few seconds difference between the various Hawaiian islands. However, you don’t really know how quickly the alert goes out. Do you estimate you’ll have more than 10 minutes notice?
The duck and cover thing I thik it was more to escape from things like glass and debris throw away by a explosion. Of course, if you were close of the explosion wold make litle sense,but the after shock can hurt lots of people.
The mocking isn't unjustifiable though. I mean the turtle/duck and cover is quite pointless, at least in the case of a nuclear strike (unless you're maybe on the far edge of it, in which case a ditch might save you..and that's big might).
In the documentary "Iraq: The Untold Story", the creator shows civilian air raid shelters in Baghdad. They were four stories down, with the upper floors all reinforced concrete. Yet there were powerless against US bunker busting bombs, and the hundreds of civilians in the shelters that were hit all died.
Cover is extremely important if you're outside the immediate fireball zone (where you're just going to be vaporized). You shouldn't infer from the fact that bunker busting bombs successfully bust bunkers that attempting to survive a nuclear explosion at some distance from you is pointless.
If you are hit directly, you're fucked no matter what. But the fireball has relatively small radius compared to the other zones.
Ducking underneath something solid is to protect you if the building collapses, which is likely to occur in the large air-blast radius. This is much like ducking under a desk in an earthquake.
Cover will save you if you're within the larger thermal radiation radius. Even clothing can be enough to protect you from burns, so any cover you can get is good.
The mocking is utterly unjustifiable. Duck and cover would have saved millions of lives if MAD had come to its conclusion. The inability of a building to resist bunker busting bombs is completely unrelated.
It could. If you’re in the inferno, no. If you’re outside the thermal flux, protected from ionising radiation by simple structure (i.e. away from windows) and within the pressure flux, duck and cover works. If you’re in cases one and two, you die, quickly or painfully. Since you don’t know ex ante where the bomb will burst, duck and cover makes sense.
It's going to make a huge difference is the blast is far enough away for you to not be in the "obliterate everything" zone, but still close enough to be dangerous.
Not common knowledge, though, in part because nuclear hazards have been painted in an exaggerated light by Hollywood (basically, no point in trying to survive, because everybody is going to die and what's going to be left is a 1,000-year lethal nuclear wasteland), and in part because we stopped worrying after the end of the Cold War.
Despite the goofy title, this is a remarkably good book from the 1960s, citing some actual science, that helps grasp the actual dangers and the survivability of nuclear attacks or accidents:
I live in a 5 story apartment with two basement floors, exactly as shown in the image. The bottom floor actually has a bomb shelter, in the area rated "200".
I've often wondered, what does "protection" mean if the building has collapsed around us, so we're now 20 feet below ground, with a pile of rubble on top, and no way to get out?
I don't think you should direct your ire towards Hollywood, at least not in any significant way. I don't think it was until "The Day After" (1983) that any movie showed anything like a realistic depiction of the aftermath of a nuclear war, and even that was deliberately downplayed.
It surely wasn't a Hollywood depiction which caused Dorothy Day and others in 1955 to protest the "Operation Alert" drill, saying:
> We will not obey this order to pretend, to evacuate, to hide. In view of the certain knowledge the administration of this country has that there is no defense in atomic warfare, we know this drill to be a military act in a cold war to instill fear, to prepare the collective mind for war. We refuse to cooperate.
Finally, the NWSS book you cited says "American official policy, or at any rate the implementation of that policy, is based on the assumption that civil defense is useless." Again, I don't think that policy was influenced by Hollywood.
(BTW, it's funny that Teller says "With the use of American automobiles an evacuation could be faster and more effective than is possible in Russia." - I guess he never saw a city trying to evacuate from a hurricane. Or the plans to evaluate NYC should there be a major disaster at Indian Point.)
Instead, NWSS and The Heritage Foundation (and an essay I read by Freeman Dyson) all say the US policy of MAD was a much bigger influence.
(I'm not going to get into a discussion of the validity of MAD. I only want to point out that I disagree with the idea that Hollywood depiction had much of a role.)
I'm not trying to establish the origin of this narrative; but most people on HN were almost certainly exposed it through pop cultural portrayals of the nuclear apocalypse.
In some cases, these were inaccurate simply because it resulted in a better movie or a novel; but in many other cases, they were probably informed by anti-war or anti-proliferation sentiments. I don't think this deserves any special ire, TBH; it's just our reality. I loved Dr. Strangelove, but it sure affected public perception in a particular way.
Just like, I imagine, most HN readers were exposed to what happened with Apollo XIII or at Dunkirk through the eponymous movies.
But I think there should be a stronger criterion than that before saying that the lack of common knowledge of the effectiveness of DIY civil defense shelters is in part due to how nuclear hazards have been portrayed by Hollywood.
It could be because they aren't effective against the type of nuclear exchange expected during the Cold War.
Most US policy makers, including Eisenhower, were convinced that there was no good civil defense against an all-out nuclear war. This lead to MAD, and the policy of MAD demands that a country not be able to protect its citizens. This was the US policy for most of the Cold War. Which means those Hollywood films reflect US policy.
A problem is, MAD requires an effective nuclear response force, with the expectation that most citizens will die. How do you convince the citizens to fund MAD? One way is to convince them that shelters are effective, even if the high-level planners know that it isn't. This was possible early on because of the secrecy about the nuclear bomb project.
The problem is, civil defense, unlike just about all other aspects of the Cold War, requires convincing the public of its effectiveness. And the government attempts were not convincing. This helped promote anti-proliferation efforts.
Which is why I don't accept your implication that because something is "informed by ... anti-proliferation sentiments" it means that we should ignore it. Those sentiments may have a reasonable basis.
Others believed in NUTS, with the possibility of a limited nuclear exchange, which is survivable for a large country like the US. NUTS played a bigger role during the Kennedy and Reagan administrations, which is why there was more government promotion of civil defense shelters then.
I'm almost certain that Teller would be in the NUTS camp. He certainly had Reagan's ear when he oversold SDI. Even if not, there were plenty of people who were, and those are the sorts of people who would (perhaps optimistically, perhaps reasonably) push that people have a nuclear bomb shelter. Teller's support of civil defense shelters was informed by his full-nuclear-response sentiments, which also "affected public perception in a particular way."
That said, the Cold War context, the idea of having a nationwide civil defense was that, after the few weeks are over and the all-clear signal given, we would help clean up and be able to return to a life that was little different than what we had before.
The reality is that, sure, perhaps a shelter could help millions more people survive the war, but come out to what sort of reality?
And it's not just Hollywood. Even before Dr. Strangelove, there were some widely read fiction books on the topic. The ones I've know are "On the Beach" (1957), "Alas, Babylon" (1959), and "Fail-Safe" (1962). (And a shout-out to "Malevil" (1972), which was the first 'modern' (post-Verne) French science fiction story I read.)
Again, the question isn't if they affected public perception "in a particular way", but rather if they lead to a more complete understanding of the topic.
And I don't think Hollywood's portrayal was much different than what was already well-known at the high policy levels, which is why I don't think it's right to single them out.
That is classic cold war stuff. Before you even get to the foreward by Edward Teller you get a preface stressing (among other things) that low doses of radiation are "healthful."
small doses of radioactivity are hormetic, healthful because they stimulate the immune system. This
was proven in laboratories as far back as the 1920's. With the advent of the A-bomb almost all the
hormetic research stopped. And only in the last decade has it resumed on a serious scale.
I wonder who they experimented on and whether that stuff is written up somewhere. Ionizing radiation is okay in my book, how about yours? is not exactly a common theme in modern medicine.
