Reference excerpt

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. Nuclear War Survival Skills aims to provide a general audience with advice on how to survive conditions likely to be encountered in the event of a nuclear catastrophe, as well as encouraging optimism in the face of such a catastrophe by asserting the survivability of a nuclear war. The 2022 edition is entitled "Nuclear War Survival Skills Updated and Expanded 2022 Edition Regarding Ukraine Russia and the World: The Best Book on Any Nuclear Incident Ever ... New Methods and Tools As New Threat Emerge".

Overview The main chapters are preceded by forewords from Edward Teller and Eugene Wigner. Following this is an introduction which explains that even the fruition of the Strategic Defense Initiative program would not make "self-help civil defense" obsolete. A comparison is made of the civil defense preparations of Switzerland, Russia, and the United States, where it is concluded that: "Switzerland has the best civil defense system"; "The rulers of the Soviet Union... continue to prepare the Russians to fight, survive, and win all types of wars"; and that "the United States has advocated... a strategy that purposely leaves its citizens unprotected hostages to its enemies." Thus, "The emphasis in this book is on survival preparations that can be made in the last few days of a worsening crisis."

The Dangers from Nuclear Weapons: Myths and Facts The first chapter aims to give background information to dispel various demoralizing myths and reaffirm the potential survivability and reality of nuclear weapons. "An all-out nuclear war between Russia and the United States would... be far from the end of human life on earth." Myths listed include: "Fallout radiation from a nuclear war would poison the air and all parts of the environment. It would kill everyone."; "Fallout radiation penetrates everything; there is no escaping its deadly effects."; and "Unsurvivable "nuclear winter" surely will follow a nuclear war."

Psychological Preparations This chapter provides information on the immediate effects of thermonuclear explosions, and peoples' likely reactions to them, in an attempt to lessen the terror and confusion that would be prevalent after an unexpected nuclear attack. "Some people would think the end of the world was upon them if they happened to be in an area downwind from surface bursts of nuclear weapons that sucked millions of tons of pulverized earth into the air."

Warnings and Communications Illustrates the limitations of the National Warning System (NAWAS) and the Attack Warning Signal sirens, concluding that "In an all-out attack, the early explosions would give sufficient warning for most people to reach nearby shelter in time."

Evacuation Due to the replacement of large warheads on inaccurate missiles with smaller warheads on more accurate missiles, "you may logically conclude that unless your home is closer than 10 miles from the nearest probable target, you need not evacuate to avoid blast and fire dangers." Evacuation relevant to fallout radiation risk is thoroughly discussed, where it is noted that most available fallout risk-area maps are inaccurate, outdated, and misleading.

Shelter, the Greatest Need Provides information on fallout protection and basic structures; complete designs for "6 types of earth-covered expedient shelters" are provided in Appendix A.

Types of radiation shielding Barrier shielding: 3 feet of earth (91 centimeters) will absorb about 99.99% of all gamma rays. If the shelter is not fully enclosed, a person is at risk of scattering gamma rays. These scattering gamma rays are known as "skyshine". Geometry Shielding reduces radiation exposure by increasing the distance from a person and the gamma particles. An effective way to create this is implementing turns into a shelter, as this makes it more difficult for gamma particles to scatter and hit a person around the corner.

Ventilation and Cooling of Shelters "Some shelters will become dangerously hot in a few hours." The Kearny air pump (for which a design is included in the appendix) is recommended, with natural ventilation considered typically inadequate, and electric pumps considered unreliable and prone to heating the air. Filters are considered unnecessary, "the hazards from fallout particles carried into shelters by unfiltered ventilating air are minor compared to the dangers from inadequate ventilation."

Protection Against Fires and Carbon Monoxide Fire is considered the third most dangerous hazard, after direct blast effects and fallout radiation. It is noted that during the Bombing of Dresden, "Most casualties were caused by the inhalation of hot gases and carbon monoxide" Fire is the third largest worry in a nuclear attack, behind initial blast and fallout radiation. The biggest killer in fires is the increased carbon monoxide. This poses an even greater threat in shelters that rely on ventilation. If a fire occurs in a shelter, occupants should move to a room where ventilation from other rooms could be cut off. When building a shelter, Dr. A. Broido suggests putting the intake vent as far from combustible materials as possible.

Water

The importance of water to basic survival is discussed, with the recommendation that four to five quarts (3.78 to 4.73 liters) of drinking water per day per person is essential as a minimum. Methods of storing, transporting, and purifying water are also explained, with plastic-lined earthen storage pits recommended for storing large quantities.

Food A basic diet, vegetarian and consisting only of bulk staples, is presented, along with basic nutrition facts and special advice for the very young, very old, and sick. "And because of the remarkable productivity of American agriculture, there usually would be enough grain and beans in storage to supply surviving Americans with sufficient food for at least a year following a heavy nuclear attack. Take precaution when eating meat. Areas with enough fallout to make animals sick, become a high-risk area for contaminated meat. If it is a crisis situation, meat should be cooked until very well done.

Worked examples

Example 1 — a first encounter with Nuclear War Survival Skills

Start with the simplest possible case. Write down what Nuclear War Survival Skills claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Nuclear War Survival Skills before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Nuclear War Survival Skills ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Nuclear War Survival Skills

In research
Nuclear War Survival Skills appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Nuclear War Survival Skills in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Nuclear War Survival Skills is common in secondary-school and first-year university syllabi. It links to neighbouring topics Books about nuclear issues, Civil defense in the United States, Cold War, so understanding it makes those chapters shorter.
In everyday life
Look for Nuclear War Survival Skills outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
