To what extent do nuclear weapons

Weapons designed to threaten large populations or to deter attacks are known as strategic weapons. Weapons whose explosive output is exclusively from fission reactions are commonly referred to as atomic bombs or atom bombs abbreviated as A-bombs. The goal in deterrence is to always maintain a second strike capability the ability of a country to respond to a nuclear attack with one of its own and potentially to strive for first strike status the ability to destroy an enemy's nuclear forces before they could retaliate.

All such weapons derive a significant portion of their energy from fission reactions used to "trigger" fusion reactions, and fusion reactions can themselves trigger additional fission reactions.

Beginning with the Partial Test Ban Treaty and continuing through the Comprehensive Test Ban Treatythere have been many treaties to limit or reduce nuclear weapons testing and stockpiles.

Critics of nuclear war strategy often suggest that a nuclear war between two nations would result in mutual annihilation.

To what extent does nuclear proliferation promote peace and stability?

By threatening retaliation against those states, the United States may be able to deter that which it cannot physically prevent. Today, missiles are most common among systems designed for delivery of nuclear weapons.

Neptunium and some isotopes of americium may be usable for nuclear explosives as well, but it is not clear that this has ever been implemented, and their plausible use in nuclear weapons is a matter of dispute.

Nuclear statesmanship- The posession of nuclear weapons by a state can instil a greater sense of responsibility and a bias towards caution in a leader.

Fission products are the principal radioactive component of nuclear fallout. Almost all of the nuclear weapons deployed today use the thermonuclear design because it is more efficient. In large, megaton-range hydrogen bombs, about half of the yield comes from the final fissioning of depleted uranium.

Advantages The fact that there has been an absence of nuclear war since the first nuclear weapons were used in to hasten the end of the war in the pacific, suggests that they are almost entirely symbolic and not of practical or strategic importance.

The Partial Nuclear Test Ban Treaty restricted all nuclear testing to underground nuclear testingto prevent contamination from nuclear fallout, whereas the Treaty on the Non-Proliferation of Nuclear Weapons attempted to place restrictions on the types of activities signatories could participate in, with the goal of allowing the transference of non-military nuclear technology to member countries without fear of proliferation.

Various American elder statesmen, [44] who were in office during the Cold War period, have been advocating the elimination of nuclear weapons. Although even short-range missiles allow for a faster and less vulnerable attack, the development of long-range intercontinental ballistic missiles ICBMs and submarine-launched ballistic missiles SLBMs has given some nations the ability to plausibly deliver missiles anywhere on the globe with a high likelihood of success.

Air Force funded studies of the physics of antimatter in the Cold Warand began considering its possible use in weapons, not just as a trigger, but as the explosive itself.

Nuclear weapon

Many fission products are either highly radioactive but short-lived or moderately radioactive but long-livedand as such, they are a serious form of radioactive contamination if not fully contained.

The only two nuclear weapons ever deployed were deployed in Hiroshima and Nagasaki for this very reason.Nuclear Weapon Explosion – Simulation According to Encarta, the damage radius increases with the power of the nuclear bomb, approximately in proportion to its cube root.

To What Extent Do Nuclear Weapons

The benefits of nuclear technology far outweigh the disadvantages. To what extent do you agree or disagree?

Fusion reactions do not create fission products, and thus contribute far less to the creation of nuclear fallout than fission reactions, but because all thermonuclear weapons contain at least one fission stage, and many high-yield thermonuclear devices have a final fission stage, thermonuclear weapons can generate at least as much nuclear fallout as fission-only weapons.

Nuclear weapons have been used twice, on the Japanese cities of Hiroshima and Nagasaki in August Evidence from these occasions, as well as atmospheric nuclear testing and nuclear power accidents have formed the basis of our knowledge of the effects of nuclear weapons.

A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission Nuclear weapons have been used twice in war, various studies were done to assess the extent of the hazard.
