nuclear weapon

Examples of nuclear weapon in the following topics:

• Nuclear Weapons

  • The proliferation of nuclear weapons, explosive devices which derive force from nuclear reactions, is a key challenge of foreign policy.
  • In addition, Israel is also widely believed to possess nuclear weapons, though it does not acknowledge having them.
  • Only two nuclear weapons have been used in the course of warfare, both by the United States near the end of World War II.
  • By the 1960s, steps were being taken to limit both the proliferation of nuclear weapons to other countries and the environmental effects of nuclear testing.
  • Identify the history of nuclear weapons and international efforts to regulate them

• Nuclear Weapons

  • A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions—either fission, fusion, or a combination.
  • A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission or a combination of fission and fusion.
  • Nuclear weapons are considered weapons of mass destruction, and their use and control have been a major focus of international relations policy since their inception.
  • In addition, it is also widely believed that Israel possesses nuclear weapons (though they have not admitted to it).
  • The first nuclear weapons were gravity bombs, such as this "Fat Man" weapon dropped on Nagasaki, Japan.

• The Nuclear Arms Race

  • The first nuclear weapon was created by U.S. during the World War II and was developed to be used against the Axis powers.
  • Scientists of the Soviet Union were aware of the potential of nuclear weapons and had also been conducting research in the field.
  • The goal of this assembly was to eliminate the use of all Nuclear weapons.
  • This period also saw some of the first attempts to defend against nuclear weapons.
  • With the end of the Cold War the United States and Russia both cut down on spending for nuclear weapons.

• The Hydrogen Bomb

  • The hydrogen bomb is a nuclear weapon that uses a mixture of fission and fusion to produce a massive explosion.
  • A thermonuclear weapon is a nuclear weapon designed to use the heat generated by a fission bomb to compress a nuclear fusion stage.
  • The fusion stage in these types of weapons is required in order to efficiently create the large quantities of fission that are characteristic of most thermonuclear weapons.
  • The only two nuclear weapons that have been used were both fission-based.
  • The basics of the Teller–Ulam design for a thermonuclear weapon.

• The Effects of the Cold War

  • Because there was no formalized treaty ending the Cold War, the former superpowers have continued to various degrees—depending on their respective economies—to maintain and even improve or modify existing nuclear weapons and delivery systems.
  • Moreover, other nations not previously acknowledged as nuclear-weapons states have developed and tested nuclear-explosive devices.
  • Moreover, during many decades of nuclear-weapons production and testing, exposure to radiation above normal background levels occurred to scientists, technicians, military personnel, civilians, and animals.
  • Because of the potential risk to national and international security, states with nuclear weapons have inherited substantial responsibilities in protecting and stabilizing their nuclear forces.
  • Not only must nuclear weapons and their delivery systems be secured and protected, other nuclear facilities and devices, such as reactors and propulsion systems, must be safeguarded.

• The Atomic Bomb

  • Atomic bombs are nuclear weapons that use the energetic output of nuclear fission to produce massive explosions.
  • Atomic bombs are nuclear weapons that use the energetic output of nuclear fission to produce massive explosions.
  • Only two nuclear weapons have been used in the course of warfare, both by the United States near the end of World War II.
  • The uranium-235 content of "weapons-grade" uranium is generally greater than 85 percent, though inefficient weapons, deemed "weapons-usable," can be made of 20 percent enriched uranium.
  • In fission weapons, a mass of fissile material, either enriched uranium or plutonium, is assembled into a supercritical mass—the amount of material needed to start an exponentially growing nuclear chain reaction.

• The Cold War's Costs and Consequences

  • Many specific nuclear legacies can be identified from the Cold War.
  • Formal and informal measures and processes have effectively slowed national incentives and the tempo of international nuclear-weapons proliferation.
  • Because there was no formalized treaty ending the Cold War, the former superpowers have continued to various degrees—depending on their respective economies—to maintain and even improve or modify existing nuclear weapons and delivery systems.
  • Moreover, other nations not previously acknowledged as nuclear-weapons states have developed and tested nuclear-explosive devices.
  • Because of potential risk to national and international security, nuclear-weapons states have inherited substantial responsibilities in protecting and stabilizing their nuclear forces.

• Binding Energy and Nuclear Forces

  • Nuclear force is the force that is responsible for binding of protons and neutrons into atomic nuclei.
  • The nuclear force is the force between two or more component parts of an atomic nuclei.
  • Nuclear force is responsible for the binding of protons and neutrons into atomic nuclei.
  • Binding energy is the energy used in nuclear power plants and nuclear weapons.
  • These nuclear forces are very weak compared to direct gluon forces ("color forces" or "strong forces") inside nucleons, and the nuclear forces extend over only a few nuclear diameters, falling exponentially with distance.

• Nuclear Binding Energy and Mass Defect

  • Once mass defect is known, nuclear binding energy can be calculated by converting that mass to energy by using E=mc2.
  • This energy—available as nuclear energy—can be used to produce nuclear power or build nuclear weapons.
  • Nuclear binding energy is also used to determine whether fission or fusion will be a favorable process.
  • As such, there is a peak at iron-56 on the nuclear binding energy curve.
  • Calculate the mass defect and nuclear binding energy of an atom

• Biological Weapons

  • Biological weapons (often termed "bio-weapons", "biological threat agents", or "bio-agents") are living organisms or replicating entities (viruses) that reproduce or replicate within their host victims.
  • Like some chemical weapons, biological weapons may also be useful as area denial weapons.
  • Toxins and psychochemical weapons are often referred to as midspectrum agents.
  • Offensive biological warfare, including the mass production, stockpiling, and use of biological weapons, was outlawed by the 1972 Biological Weapons Convention (BWC).
  • Biological weapons allow for the potential to create a level of destruction and loss of life far in excess of nuclear, chemical, or conventional weapons, relative to their mass and cost of development and storage.
