Civil defense or civil protection is an effort to protect the citizens of a state from human-made and natural disasters. It uses the principles of emergency operations: prevention, mitigation, preparation, response, or emergency evacuation and recovery. Programs of this sort were initially discussed at least as early as the 1920s and were implemented in some countries during the 1930s as the threat of war and aerial bombardment grew. Civil-defense structures became widespread after authorities recognised the threats posed by nuclear weapons.
A fallout shelter is an enclosed space specially designated to protect occupants from radioactive debris or fallout resulting from a nuclear explosion. Many such shelters were constructed as civil defense measures during the Cold War.
Nuclear warfare, also known as atomic warfare, is a military conflict or prepared political strategy that deploys nuclear weaponry. Nuclear weapons are weapons of mass destruction; in contrast to conventional warfare, nuclear warfare can produce destruction in a much shorter time and can have a long-lasting radiological result. A major nuclear exchange would likely have long-term effects, primarily from the fallout released, and could also lead to secondary effects, such as "nuclear winter", nuclear famine, and societal collapse. A global thermonuclear war with Cold War-era stockpiles, or even with the current smaller stockpiles, may lead to various scenarios including the extinction of the human species.
Nuclear fallout is the residual radioactive material propelled into the upper atmosphere following a nuclear blast, so called because it "falls out" of the sky after the explosion and the shock wave has passed. It commonly refers to the radioactive dust and ash created when a nuclear weapon explodes. The amount and spread of fallout is a product of the size of the weapon and the altitude at which it is detonated. Fallout may get entrained with the products of a pyrocumulus cloud and fall as black rain. This radioactive dust, usually consisting of fission products mixed with bystanding atoms that are neutron-activated by exposure, is a form of radioactive contamination.
A bunker is a defensive military fortification designed to protect people and valued materials from falling bombs, artillery, or other attacks. Bunkers are almost always underground, in contrast to blockhouses which are mostly above ground. They were used extensively in World War I, World War II, and the Cold War for weapons facilities, command and control centers, and storage facilities. Bunkers can also be used as protection from tornadoes.
Radiological warfare is any form of warfare involving deliberate radiation poisoning or contamination of an area with radiological sources.
Protect and Survive was a public information campaign on civil defence. Produced by the British government between 1974 and 1980, it intended to advise the public on how to protect themselves during a nuclear attack. The campaign comprised a pamphlet, newspaper advertisements, radio broadcasts, and public information films. The series had originally been intended for distribution only in the event of dire national emergency, but provoked such intense public interest that the pamphlet was published, in slightly amended form, in 1980. Due to its controversial subject, and the nature of its publication, the cultural impact of Protect and Survive was greater and longer-lasting than most public information campaigns.
"Duck and cover" is a method of personal protection against the effects of a nuclear explosion. Ducking and covering is useful in offering a degree of protection to personnel located outside the radius of the nuclear fireball but still within sufficient range of the nuclear explosion that standing upright and uncovered is likely to cause serious injury or death. In the most literal interpretation, the focus of the maneuver is primarily on protective actions one can take during the first few crucial seconds-to-minutes after the event, while the film of the same name and a full encompassing of the advice also cater to providing protection up to weeks after the event.
Duck and Cover is a 1952 American civil defense animated live-action social guidance film that is often popularly mischaracterized as propaganda.
Since their public debut in August 1945, nuclear weapons and their potential effects have been a recurring motif in popular culture, to the extent that the decades of the Cold War are often referred to as the "atomic age".
A blast shelter is a place where people can go to protect themselves from blasts and explosions, like those from bombs, or in hazardous worksites, such as on oil and gas refineries or petrochemical facilities. It differs from a fallout shelter, in that its main purpose is to protect from shock waves and overpressure instead of from radioactive precipitation, as a fallout shelter does. It is also possible for a shelter to protect from both blasts and fallout.
United States civil defense refers to the use of civil defense in the history of the United States, which is the organized non-military effort to prepare Americans for military attack and similarly disastrous events. Late in the 20th century, the term and practice of civil defense fell into disuse. Emergency management and homeland security replaced them.
Survival Under Atomic Attack was the title of an official United States government booklet released by the Executive Office of the President, the National Security Resources Board, and the Civil Defense Office. Released at the onset of the Cold War era, the pamphlet was in line with rising fears that the Soviet Union would launch a nuclear attack against the United States, and outlined what to do in the event of an atomic attack.
Nuclear War Survival Skills or NWSS, by Cresson Kearny, is a civil defense manual. It contains information gleaned from research performed at Oak Ridge National Laboratory during the Cold War, as well as from Kearny's extensive jungle living and international travels.
Civil Defence Information Bulletin were a series of seven public information films dealing with civil defence measures individuals and families could take in the event of a nuclear attack on Great Britain. They were produced for the Home Office and the Scottish Home and Health Department by RHR Productions United Kingdom in 1964. The writer was Nicolas Alwyn and the producer Ronald H. Riley, and it starred Robert Urquhart.
In the survivalist subculture or movement, a retreat is a place of refuge. Sometimes their retreats are called a bug-out location (BOL), a bunker, a bolt hole or a hidesite. Survivalist retreats are intended to be self-sufficient and easily defended. Generally, they are located in sparsely populated outback rural areas.
Abo Elementary School in Artesia, New Mexico, United States, was the first public school in the United States constructed entirely underground and equipped to function as an advanced fallout shelter. Designed at the height of the Cold War and completed in 1962, the school had a concrete slab roof which doubled as the school's playground. It contained a large storage facility with room for emergency rations and supplies for up to 2,160 people in the event of nuclear warfare or other catastrophe. The building was listed on the National Register of Historic Places in 1999.
"The Shelter" is episode 68 of the American television anthology series The Twilight Zone. It originally aired on September 29, 1961 on CBS. It is one of the few Twilight Zone episodes to feature no supernatural or sci-fi elements.
Many countries around the world have civil defense organizations dedicated to protecting civilians from military attacks and providing rescue services after widespread disasters. In most countries, civil defense is a government-managed and often volunteer-staffed organization.
