Nuclear weapon design The Trinity test of the Manhattan Project was the first detonation of a nuclear weapon, which lead J. Robert Oppenheimer to recall verses from the Hindu scripture Bhagavad Gita: Weapons whose explosive output is exclusively from fission reactions are commonly referred to as atomic bombs or atom bombs abbreviated as A-bombs.

This has long been noted as something of a misnomeras their energy comes from the nucleus of the atom, just as it does with fusion weapons. In fission weapons, a mass of fissile material enriched uranium or plutonium is Nuclear arms race make the world into supercriticality —allowing an exponential growth of nuclear chain reactions —either by shooting one piece of sub-critical material into another the "gun" method or by compressing using explosive lenses a sub-critical sphere of material using chemical explosives to many times its original density the "implosion" method.

The latter approach is considered more sophisticated than the former, and only the latter approach can be used if the fissile material is plutonium. The amount of energy released by fission bombs can range from the equivalent of just under a ton to upwards oftons kilotons of TNT 4.

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. Fission products are the principal radioactive component of nuclear fallout.

The most commonly used fissile materials for nuclear weapons applications have been uranium and plutonium Less commonly used has been uranium 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.

Thermonuclear weapon The basics of the Teller—Ulam design for a hydrogen bomb: The other basic type of nuclear weapon produces a large proportion of its energy in nuclear fusion reactions.

How Washington Provoked—and Perhaps Lost—a New Nuclear-Arms Race

Such fusion weapons are generally referred to as thermonuclear weapons or more colloquially as hydrogen bombs abbreviated as H-bombsas they rely on fusion reactions between isotopes of hydrogen deuterium and tritium.

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.

Whether India has detonated a "true" multi-staged thermonuclear weapon is controversial. Almost all of the nuclear weapons deployed today use the thermonuclear design because it is more efficient. In the Teller-Ulam designwhich accounts for all multi-megaton yield hydrogen bombs, this is accomplished by placing a fission bomb and fusion fuel tritiumdeuteriumor lithium deuteride in proximity within a special, radiation-reflecting container.

When the fission bomb is detonated, gamma rays and X-rays emitted first compress the fusion fuel, then heat it to thermonuclear temperatures. The ensuing fusion reaction creates enormous numbers of high-speed neutronswhich can then induce fission in materials not normally prone to it, such as depleted uranium.

Each of these components is known as a "stage", with the fission bomb as the "primary" and the fusion capsule as the "secondary".

In large, megaton-range hydrogen bombs, about half of the yield comes from the final fissioning of depleted uranium.

This technique can be used to construct thermonuclear weapons of arbitrarily large yield, in contrast to fission bombs, which are limited in their explosive force. Most thermonuclear weapons are considerably smaller than this, due to practical constraints from missile warhead space and weight requirements.

Other types Main articles: Boosted fission weaponNeutron bombRadiological warfareand Antimatter weapon There are other types of nuclear weapons as well. For example, a boosted fission weapon is a fission bomb that increases its explosive yield through a small number of fusion reactions, but it is not a fusion bomb.

In the boosted bomb, the neutrons produced by the fusion reactions serve primarily to increase the efficiency of the fission bomb. There are two types of boosted fission bomb: Some nuclear weapons are designed for special purposes; a neutron bomb is a thermonuclear weapon that yields a relatively small explosion but a relatively large amount of neutron radiation ; such a device could theoretically be used to cause massive casualties while leaving infrastructure mostly intact and creating a minimal amount of fallout.

The detonation of any nuclear weapon is accompanied by a blast of neutron radiation. Surrounding a nuclear weapon with suitable materials such as cobalt or gold creates a weapon known as a salted bomb.

This device can produce exceptionally large quantities of long-lived radioactive contamination.

It has been conjectured that such a device could serve as a "doomsday weapon" because such a large quantity of radioactivities with half-lives of decades, lifted into the stratosphere where winds would distribute it around the globe, would make all life on the planet extinct.

In connection with the Strategic Defense Initiativeresearch into the nuclear pumped laser was conducted under the DOD program Project Excalibur but this did not result in a working weapon.

The concept involves the tapping of the energy of an exploding nuclear bomb to power a single-shot laser which is directed at a distant target.China steps up pace in new nuclear arms race with US and Russia as experts warn of rising risk of conflict.

The arms trade is big business, with some trillion dollars being spent on military budgets and purchases each year around the world. This page provides some numbers and breakdowns of who sells most of the arms, and who buys them.
