Duck and Cover (1951)
After nuclear weapons were developed (the first having been developed during the Manhattan Project during World War II), it was realized what kind of danger they posed. The United States held a nuclear monopoly from the end of World War II until 1949, when the Soviets detonated their first nuclear device. This signaled the beginning of the nuclear stage of the Cold War, and as a result, strategies for survival were thought out. Fallout shelters, both private and public, were built, but the government still viewed it as necessary to explain to citizens both the danger of the atomic (and later, hydrogen) bombs, and to give them some sort of training so that they would be prepared to act in the event of a nuclear strike. The solution was the duck and cover campaign, of which Duck and Cover was an integral part. Shelters were built, drills were held in towns and schools, and the film was shown to schoolchildren. According to the United States Library of Congress (which declared the film "historically significant" and inducted it for preservation into the National Film Registry in 2004), it "was seen by millions of schoolchildren in the 1950s."
There is controversy from some people regarding the actual usefulness of the film. Since it has no counterpart in any other country (although the British film Protect and Survive is somewhat similar), it is sometimes regarded as being a red scare political tool, to make children frightened of the Soviet Union and communism. Also questioned is the film's scientific accuracy; whether or not the tactics shown in the film (such as ducking into a doorway, putting a newspaper over your head, and even just throwing yourself face down on the ground) would actually work. While this (or any) tactic would be useless for someone at ground zero during a nuclear blast, it could be beneficial for those who are positioned away from the blast hypocenter: both the thermal pulse of some weapons and shrapnel from all weapons (particularly from shattered windows) could be evaded. In particular, higher yield thermonuclear weapons have thermal pulses which last for several seconds. By promptly putting something between yourself and the fireball, you could avoid or reduce the severity of the burns you would have otherwise received. For those not at ground zero, there would be a delay between the flash (indicating the need to duck and cover) and the arrival of the blast wave, which could shatter windows and cause other blast or impact injuries (although electromagnetic radiation, such as infra-red and gamma rays, would arrive at the observer's position at the same time as the light flash, leaving the observer no time to find cover from these particular aspects of a nuclear detonation). A newspaper would, at least in theory, block alpha radiation although skin does this anyway, provide some shielding from the heat (IR, visible and UV) radiation and small debris, though it would have no effect on the beta and gamma radiation or on the shockwave that would accompany an atomic detonation.
