Duck and Cover (film)

Duck and Cover is a 1952 civil defense animated live-action social guidance film that is often popularly mischaracterized as propaganda.
With similar themes to the more adult oriented civil defense training films, the film was widely distributed to United States schoolchildren in the 1950s. It instructionally teaches students on what to do in the event of a nuclear explosion. 
The film was funded by the US [[Federal Civil Defense Administration]] and released in January 1952. At the time, the [[Soviet Union]] was engaged in [[Joe-1|nuclear testing]] and the US was in the midst of the [[Korean War]].
The film was written by Raymond J. Mauer, directed by Anthony Rizzo of Archer Productions, narrated by actor [[Robert Middleton]], and made with the help of schoolchildren from [[New York City]] and [[Astoria, Queens|Astoria]], [[New York (state)|New York]].
The film is now in the [[public domain]], and is widely available through Internet sources such as [[YouTube]], as well as on [[DVD]]. It was selected by the [[National Film Registry]] for preservation in 2004 for being "culturally, historically, or esthetically significant." The film has been screened fairly often on [[Turner Classic Movies]]' Saturday night–Sunday morning film showcase series, [[TCM Underground]].
Plot summary.
[[File:Duck and Cover 1440 x 1080 01836081.webm|thumb|Full film from the [[Library of Congress]]]]
The film starts with an [[animated cartoon|animated sequence]], showing an [[anthropomorphism|anthropomorphic]] [[turtle]] walking down a road, while picking up a flower and smelling it. A [[choir|chorus]] sings the "Duck and Cover" theme:
[[File:d and c.jpg|thumb|The significant scene before Bert ducks and covers.]]Under the theme, Bert is shown being attacked by a [[monkey]] holding a lit [[firecracker]] or stick of [[dynamite]] on the end of a string. Bert ducks into his [[Exoskeleton|shell]] in the nick of time, as the charge goes off and destroys both the monkey and the tree in which he is sitting. Bert, however, is shown perfectly safe, because he ducked and covered.
The film then switches to [[live-action|live footage]], as narrator Middleton explains what children should do "when you see the flash" of an [[Nuclear weapon#Fission bombs|atomic bomb]]. The movie goes on to suggest that by ducking down low in the event of a [[nuclear explosion]], (crawling under desks and covering their necks with clasped hands) the children would be safer than they would be standing, and explains some basic survival tactics for nuclear war (facing any wall that might lend protection).
The last scene of the film returns to animation in which Bert the Turtle (voiced by Carl Ritchie) summarily asks what everybody should do in the event of an atomic bomb flash and is given the correct answer by a group of unseen children.
Purpose.
After [[nuclear weapon]]s were developed ([[Trinity (nuclear test)|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 shelter]]s, 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, [[Teller–Ulam design|hydrogen]]) bombs, and to give them some sort of training so that they would be prepared to act in the event of a [[nuclear warfare|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." 
Other media.
The song "Bert the Turtle (Duck and Cover)", performed by [[Dick Baker (musician)|Dick Baker]], was released as a commercial recording by [[Coral Records]] and accompanied by a color campaign pamphlet. It sold three million copies.
Accuracy and usefulness.
[[File:Operation Castle - Nectar - Detonation.ogv|thumb|right| Test shot "Nectar" of [[Operation Castle]] produced a yield of 1.69 [[TNT equivalent|megaton]]s. Note the distinctive near instantaneous "[[Bhangmeter|double flash]]", with the second being brighter than the sun, and the [[blast wave]] slowly, by comparison, spreading out turning the calm [[Elugelab]] ocean water a [[mie scattering|frothy white]] as it passes. The maximum average [[nuclear fireball]] radius is approximately . The outdoor blast and thermal burn [[LD50]]s would be 8 and 12 km respectively. Assuming personnel did not take any prompt countermeasures.]]
Many historians and the [[nuclear disarmament]] public at large have generally sought to mock and dismiss civil defense advice as mere propaganda, including Amy Lutrell, who argues the film was made primarily as an American [[red scare]] political tool, to make children frightened of the [[Soviet Union]] and [[communism]].
Detailed scientific research programs lay behind the much-mocked UK government civil defense pamphlets of the 1950s and 1960s, including the advice to promptly duck and cover. The advice to "duck and cover" has made a resurgence in recent years with new scientific evidence to support it.
While this (or any) tactic would be useless for someone at [[ground zero]] during a [[surface burst]] [[nuclear explosion]], it would be beneficial to the vast majority of people who are positioned away from the blast [[hypocenter]]: both the thermal pulse of some weapons and the shrapnel from all weapons (particularly from shattered windows) could be evaded, at least in part. In particular, higher yield [[nuclear weapon design|thermonuclear weapon]]s have thermal pulses which last for several seconds. By promptly putting something between yourself and the fireball during these crucial couple of seconds, you could avoid or reduce the severity of the burns you would have otherwise received. For those not at ground zero, like a shortened version of the delay between lightning and thunder, there would be a delay between the flash (indicating the need to duck and cover) and the arrival of the blast wave, which will shatter windows turning non-safety glass into missile-like shards, and cause other blast or impact injuries.
To highlight the effect that being indoors can make, despite the lethal radiation & blast zone extending well past her position at Hiroshima, Akiko Takakura survived the [[Little Boy|effects of a 16 kt atomic bomb]] at a distance of 300 meters from the hypocenter, with only minor injuries, due in most part to her position in the lobby of the bank of Japan, a [[reinforced concrete]] building, at the time of the nuclear explosion. In contrast, the unknown person sitting outside, fully exposed, on the steps of the Sumitomo bank, next door to the bank of Japan, received third-degree burns and was then likely killed by the blast, in that order, within 2 seconds.
The advice to cover one's head with anything available, like the picnic blanket and newspaper used by the family in the film, may seem absurd at first when one considers the capabilities of a nuclear weapon, but even a thin barrier such as cloth can reduce the severity of burns on the skin from the [[Effects of nuclear explosions#Thermal radiation|thermal radiation]] – which is light rays in the ultraviolet, visible, and infrared range, and it is this combination of light rays that delivers the burning energy to exposed skin areas; this burning thermal energy would be experienced by people within range for several seconds after the explosion. A photograph taken about 1.3 km from the hypocenter of the [[Atomic bombings of Hiroshima and Nagasaki|Hiroshima bomb explosion]] showed that even leaves from a nearby shrub protected a wooden telephone pole from charring discoloration due to thermal radiation, while the rest of the telephone pole not under the protection of the leaves was charred almost completely black.
Depending on the yield and distance from the explosion the burst of [[ionizing radiation]] from the fireball would arrive at an observer's position at the same time as the light flash, leaving the observer little to no time to find cover from this aspect of a nuclear detonation, but subsequently some of this radiation is absorbed and re-emitted by heated fireball air molecules at lower wavelengths, so harmful ionizing radiation may continue for up to a minute during which time ducking and covering would go some way in limiting one's exposure.
Alongside the misapprehension that all nuclear weapons have increased in yield to levels of the 50 Megaton [[Tsar Bomba]], instead of the reality that the more militarily effective and numerous nuclear weapons are those akin to the [[W76]] and Russian [[RSM-56 Bulava|Bulava]], which have a yield of approximately 100 to 200 kiloton(0.2 Megaton) and as it is these explosive devices that equip the submarine fleets of the US, Britain and Russia, it is therefore these explosive devices that are most likely to be encountered by civilians. The other similarly common misapprehension or criticism of duck and cover that is frequently encountered is the opinion that prompt [[ionizing radiation]] effects would still kill those who duck and cover, regardless of any preventive measures taken. However this is generally incorrect when any nuclear weapon more powerful than 10–30 [[kiloton]]s is detonated, and even in that case, if the person is indoors the absorbed radiation dose is again not life-threatening. For example, despite the film not being made in the era of megaton-range weapons, for exposed individuals taking no preventive countermeasures the range of harmful ionising radiation effects stays within a circle of radius 2–3 km from ground zero during airbursts of 1 megaton in yield, yet the blast range that would be expected to be [[LD50|lethal to 50% of people]] is 7.5 km, and the range of thermal effects lethal to 50% of people stretching out to 11 km from ground zero. Naturally, within this 3 km range from a 1-megaton airburst, the fatality rate would be near total for those caught in the open from the extreme blast pressure alone, before any potential radiation sickness could begin.
However, for one caught in the open outside this ~3-kilometer radius from ground zero from a 1-megaton weapon, ducking and covering would drastically increase one's chance of survival, as at this range the radiation hazard is near zero, whereas that from the blast is a chance of 50% fatality at a ~7.5 km range and that of thermal effects 11 km.
If someone was caught in the open, and by surprise, by the same 1-megaton weapon detonation, but ducked and covered in 2 seconds time from first noticing the moment of flash, then that person would have prevented themselves from being exposed to the full brunt of the 1-megaton explosion's thermal energy; instead, approximately 55% of the explosion's total thermal flash energy would have been absorbed over these 2 seconds. In this example, as there is now a 45% reduction in the amount of heat experienced by one ducking and covering, the [[LD50|median lethal thermal range]] from this 1-megaton weapon can now be more accurately described as equivalent to absorbing the entire flash energy from a 0.55 Mt or 550 kt weapon, if one ducks and covers in 2 seconds.
Hence, one's chance of survival at 11 km goes from the previous 50% chance of death if they just stood there, gazing at the 1-megaton fireball as it emits all its energy over tens of seconds, to now a mere sunburn, or a [[Burn|1st-degree burn]] injury on exposed skin. With the 50% lethal thermal range being thus downrated to being equivalent to a 550 kt explosion, the 50% lethal thermal radius goes from the previous 11 km without ducking and covering to ~7 km with prompt duck and covering within 2 seconds. 
One can think of this as going from a scenario were before the majority of people caught in the open, who just stood there staring at the fireball out to a radius of 11 km would probably die from lethal [[Burn|3rd-degree burns]] on their unclothed skin, to a scenario now were instead the vast majority of people who 'duck and cover' from 7 km out to 11 km would remain alive, with generally non life-threatening [[Burn|1st-degree burns]] and [[Burn|2nd-degree burns]] over their exposed skin, with the burn severity naturally depending on their range from the explosion.
Finally, all the lethal ranges given in the referenced graphs, and when discussing the range of [[Effects of nuclear explosions]] in general, one must keep in mind what is presented is the most pessimistic of weapon effects ranges. As the scaling laws these tables and graphs were derived from assume a simplistic flat terrain with no intervening skyscrapers or other objects that would attenuate the blast and provide shadowing from the thermal effects. When real world city terrain [[topography]] is included in these weapon effects calculations the lethal ranges are downgraded considerably.
According to the 1946 book [[Hiroshima (book)|Hiroshima]], in the days between the Hiroshima and Nagasaki atomic bombs in Japan, one Hiroshima policeman went to Nagasaki to teach police about ducking after the atomic flash. As a result of this timely warning, not a single Nagasaki policeman died in the initial blast. This allowed more surviving Nagasaki police to organize relief efforts than in Hiroshima. Unfortunately, the general population was not warned of the heat/blast danger following an atomic flash because of the bomb's unknown nature. Many people in Hiroshima and Nagasaki died while searching the skies for the source of the brilliant flash.
Recent scientific analysis has largely supported the general idea of sheltering indoors in response to a nuclear explosion. Staying indoors can offer protection both from the initial blast as well as the following radioactive [[fallout]] that accumulates during the aftermath. Additionally, such a response would leave roads clear for emergency vehicles to access the area. This is termed the [[Shelter in place]] protocol, and together with [[emergency evacuation]] advice, they are the two countermeasures to take when the direct effects of nuclear explosions are no longer life-threatening and the need for protective shielding from coming in contact with nuclear weapon debris/[[fallout]] in the aftermath of the explosion, begins to become a concern.
Historical context.
[[File:Operation Teapot test.ogv|thumb|Video of shot "MET" (Military Effects Test) of [[Operation Teapot]], fired on 15 April 1955, with a yield of 22 [[kilotons]], typical of the yield of nuclear weapons when the film was first shown and approximately of the same yield and [[effects of nuclear weapons|height of burst]] as the [[Fat Man]] bomb detonated over the city of Nagasaki in 1945.]]
The United States' monopoly on [[nuclear weapon]]s was broken by the [[Soviet Union]] in 1949 when it [[Joe 1|tested its first nuclear explosive]] (Joe-1), and with this many in the US government and public perceived that the nation was more vulnerable than it had ever been before. Duck-and-cover exercises quickly became a part of [[Civil Defense]] drills that every American citizen, from children to the elderly, practiced to be ready in the event of [[Nuclear warfare|nuclear war]]. In 1950, during the first big Civil Defense push of the [[Cold War]] and coinciding with the "Alert America!" initiative to educate Americans on nuclear preparedness; The adult-orientated [[Survival Under Atomic Attack]] was published and contains "duck and Cover" or more accurately, cover-and-then-duck advice without using those specific terms in its "Six Survival Secrets For Atomic Attacks" section. "1. Try To Get Shielded 2.Drop Flat On Ground Or Floor 3. Bury Your Face In Your Arms("crook of your elbow")". The child-orientated "Duck and Cover (film)" was produced a year later by the [[Federal Civil Defense Authority|Federal Civil Defense Administration]] in 1951.
[[Image:SurvivalUnderAtomicAttack.jpg|right|thumb|250px|The adult-orientated "[[Survival Under Atomic Attack]]" issued in 1950, pre-dated the release of "Duck and Cover" in 1951–52. The Booklet was accompanied by a companion film by the same name.]]
Education efforts on the effects of nuclear weapons proceeded with stops-and-starts in the US due to competing alternatives. In a once classified, 1950s era, US [[Military simulation|war game]] that looked at varying levels of war escalation, warning and pre-emptive attacks in the late 1950s early 1960s, it was estimated that approximately 27 million US citizens would have been saved with civil defense education. At the time however the cost of a full-scale civil defense program was regarded as lesser in effectiveness, in [[cost-benefit analysis]] than a [[ballistic missile defense]] ([[Nike Zeus]]) system, and as the Soviet adversary was believed to be rapidly increasing their [[nuclear stockpile]], the [[efficacy]] of both would begin to enter a [[diminishing returns]] trend. When more became known about the cost and limitations of the [[Nike Zeus]] system, in the early 1960s the [[United States Secretary of Defense|head of the department of defense]] determined once again that [[fallout shelter]]s would save more Americans for far less money.
The production of the Duck and Cover film in 1951 by the [[Federal Civil Defense Authority|Federal Civil Defense Administration]] occurred during the height of the [[Korean War]] (1950–1953), and coincided with the first [[Desert Rock exercises]] in the Nevada desert which were designed to familiarize the US military with fighting alongside [[tactical nuclear weapons|battlefield nuclear weapons]], as it was feared that a resolution to the Korean War might need the [[theatre of operations]] to first expand across the border into the [[People's Republic of China]] and require nuclear weapons to end it.
The film was also produced at least one year before the first "[[hydrogen bomb]]" or [[TNT equivalent|megaton]] range explosive device was demonstrated to be possible, with test shot [[Ivy Mike]] in 1952. At least four years before the first true "hydrogen bomb" of the [[Soviet Union]] (USSR), the [[RDS-37]], on November 22, 1955, which yielded 1.6 megatons. About 6 years before the first successful test launch of the world's first [[intercontinental ballistic missile]] (ICBM), the Soviet Union's [[SS-6 Sapwood|R-7]] in 1957, up until this time [[strategic bombers]] were not but one of the three strategic [[nuclear triad]] delivery systems of the modern era but the sole intercontinental [[nuclear weapon delivery systems|nuclear weapon delivery system]] capable of reaching the US from the Soviet Union and vice versa.
Before advances in [[precision guided munition]]s and [[physics package]] miniaturization, "city busting" or [[countervalue]] targeting, was a more likely nuclear war scenario, as effective [[counterforce]] warfare with nuclear weapons had yet to become all that conceivable, with the potential exceptions of being used in roles where a low degree of accuracy would not result in a waste of a bomb, such as destroying large "rear area" military bases, [[aircraft carriers]], Communist [[human wave attacks]], [[Field fortifications#Post-1945 trench warfare|massive mine fields]] in [[trench warfare]] (which was what the Korean War escalated into), radiological [[area denial]] and used at night prior to a [[frontal assault]] in the hopes of inducing widespread enemy troop [[flash blindness]]. Practically all other counterforce uses of this eras nuclear weapons would be ineffective due to [[force dispersal]], weather factors, poor [[Circular error probable|munition accuracy]] and the unwieldy physics packages of the [[Mark 4 nuclear bomb|nuclear weapons of the era]], making them generally unfit for the [[maneuver warfare|mobile battlefield]]. This would therefore make it likely that combatants who have escalated to the point of contemplating nuclear exchanges would use their nuclear weapons on immobile and valuable targets, such as the war supporting infrastructure of cities.
It is now estimated that it was not until after 1957 that the [[USSR]] attained more than about 50 [[nuclear weapon|nuclear munition]]s in its [[List of states with nuclear weapons|nuclear weapons arsenal]]. Almost all of this stockpile was likely designed to be air dropped by the [[Myasishchev M-4]] and [[Tupolev Tu-4]] bombers as [[strategic nuclear weapons]] on US and West European [[NATO]] cities respectively. Large numbers of small true [[tactical nuclear weapon]]s only began to seriously populate the USSR's stockpile in the [[2S3 Akatsiya|1970s]] and beyond.
Appearance in other media.
The 1982 film "[[The Atomic Cafe]]", a satirical [[collage film|collage documentary film]], uses footage from the "Duck and Cover". Both films (the documentary in 2016) were inducted into the [[National Film Registry]].
The video for [["Weird Al" Yankovic]]'s 1986 song '[[Christmas at Ground Zero]]' features footage from the film, mostly during an instrumental break. Bert the Turtle is shown in time with the lyric 'I'll duck and cover/ with my Yuletide lover'.
The video for Peter Gabriel's 1980 song '[[Games Without Frontiers]]' features footage from the film at the end of song.
The 2015 Oscar-winning film "[[Bridge of Spies (film)|Bridge of Spies]]", about an exchange of captured spies between the U.S. and Soviet Union during the Cold War, features a prominent scene in which grade school children watch "Duck and Cover" in their classroom.
In the 1997 [[South Park]] episode "[[Volcano (South Park)|Volcano]]", the South Park residents are urged to "duck and cover" by a volcano safety film which loosely parodies the 1950s film Duck and Cover. This proves ineffective as the people who follow the film's advice are subsequently disintegrated by the lava from the volcanic eruption with only their skeletons remaining.
The 1999 Warner Brothers animated feature film, "[[The Iron Giant]]," set in 1957, features a [[social guidance film]]-within-a-film titled, "Atomic Holocaust," the style and tone of which parodies the film. In another instance, near the end of the feature film, the villainous character Kent Mansley suggests they duck and cover into a fallout shelter in response to an offshore nuclear [[SLBM]] [[Polaris missile]] being launched at their position by the [[USS Nautilus (SSN-571)|USS "Nautilus"]], however all the other male adults in the vicinity claim that this would be of "no use", convincing bystanders and the young protagonist at the heart of the feature film to not attempt to evacuate to shelter.
[[RiffTrax]] has for sale a riffed version of this film.
