Neutron bomb

A neutron bomb, technically referred to as an enhanced radiation weapon (ERW), is a type of tactical nuclear weapon formerly built mainly by the United States specifically to release a large portion of its energy as energetic neutron radiation. This contrasts with standard thermonuclear weapons, which are designed to capture this intense neutron radiation to increase its overall explosive yield. In terms of yield, ERWs typically produce about one-tenth that of a fission-type atomic weapon. Even with their significantly lower explosive power, ERWs are still capable of much greater destruction than any conventional bomb. Meanwhile, relative to other nuclear weapons, damage is more focused on biological material than on material infrastructure (though extreme blast and heat effects are not eliminated—see Technical overview below).

History

Conception of the neutron bomb is generally credited to Samuel Cohen of the Lawrence Livermore National Laboratory, who developed the concept in 1958. Although initially opposed by President John F. Kennedy, its testing was authorized and carried out in 1963 at an underground Nevada test facility. Development was subsequently postponed by President Jimmy Carter in 1978 following protests against his administration's plans to deploy neutron warheads in Europe. President Ronald Reagan restarted production in 1981.

Three types of ERW were built by the United States. The W66 warhead, for the anti-ICBM Sprint missile system, was produced and deployed in the mid 1970s and retired soon thereafter, along with the missile system. The W70 Mod 3 warhead was developed for the short-range, tactical Lance missile, and the W79 Mod 0 was developed for artillery shells. The latter two types were retired by President George H. W. Bush in 1992, following the end of the Cold War. The last W70 Mod 3 warhead was dismantled in 1996, and the last (W79 Mod 0) was dismantled by 2003, when the dismantling of all W79 variants was completed..

France tested a neutron bomb at the Mururoa Atoll on June 24, 1980. Enhanced radiation weapons were also produced by France in the early 1980s, though they have since destroyed these weapons. The 1999 "Cox Report" indicates that China is able to produce neutron bombs,, although no country is currently known to deploy them.

Technical overview

An ERW is a fission-fusion thermonuclear weapon in which the burst of neutrons generated by a fusion reaction is intentionally allowed to escape the weapon, rather than being absorbed by its other components. The weapon's X-ray mirrors and shell are made of chromium or nickel so that the neutrons can escape. Contrast this with cobalt bombs, also known as salted bombs.

Neutron bombs have low yields compared with other nuclear weapons. This is because neutrons are absorbed by air, so a high-yield neutron bomb is not able to radiate neutrons beyond its blast range and so would have no destructive advantage over a normal hydrogen bomb. Note that using the explosive yield of ERWs to measure destructive power can be deceptive: most of the injuries caused by an ERW come from ionizing radiation, not from heat and blast.

This intense burst of high-energy neutrons is intended as the principal killing mechanism, although large amounts of heat and blast are also produced. Although neutron bombs are commonly believed to "leave the infrastructure intact", current designs have explosive yields in the kiloton range,, the detonation of which would cause heavy destruction through blast and heat effects. A yield of one kiloton is not high for a nuclear weapon, but is still nearly two orders of magnitude (100 times) bigger than the most powerful conventional bombs.

One of the uses for which this weapon was conceived is large-scale anti-tank weaponry. Armored vehicles offer a relatively high degree of protection against heat and blast, the primary destructive mechanisms of normal nuclear weapons. That is, military personnel inside a tank can be expected to survive a nuclear explosion at relatively close range, while the vehicle's NBC protection systems ensure a high degree of operability even in a nuclear fallout environment. By contrast, ER weapons are meant to kill a much higher percentage of enemy personnel inside such protected environments through the release of a higher percentage of their yield in the form of neutron radiation, against which even tank armor is not very effective.

The term enhanced radiation refers only to the burst of neutron radiation released at the moment of detonation, not to any enhancement of residual radiation in fallout.

A neutron bomb requires considerable amounts of tritium, which has a half-life of 12.3 years, compounding the difficulties of extended storage. For a weapon to remain effective over time, tritium components would have to be periodically replaced.

Neutron bomb tactics

Neutron bombs could be used as strategic anti-ballistic missile weapons or as tactical weapons intended for use against armored forces; in fact, the neutron bomb was originally conceived as a weapon that could stop Soviet armored divisions from overrunning Western Europe without destroying Western Europe in the process.

As an anti-ballistic missile weapon, an ER warhead was developed for the Sprint missile system as part of the Safeguard Program to protect United States cities and missile silos from incoming Soviet warheads by damaging their electronic components with the intense neutron flux.

Tactical neutron bombs are primarily intended to kill soldiers who are protected by armor. Armored vehicles are extremely resistant to blast and heat produced by nuclear weapons, so the effective range of a nuclear weapon against tanks is determined by the lethal range of the radiation, although this is also reduced by the armor. By emitting large amounts of lethal radiation of the most penetrating kind, ER warheads maximize the lethal range of a given yield of nuclear warhead against armored targets.

One problem with using radiation as a tactical anti-personnel weapon is that to bring about rapid death of the individuals targeted, a radiation dose that is many times the lethal level must be administered. A radiation dose of 6 Gy is normally considered lethal. It will kill at least half of those who are exposed to it, but no effect is noticeable for several hours. Neutron bombs were intended to deliver a dose of 80 Gy to quickly kill targets. A 1 kt ER warhead can do this to a T-72 tank crew at a range of 690 m, compared to 360 m for a pure fission bomb. For a 6 Gy dose, the distances are 1100 m and 700 m respectively, and for unprotected soldiers 6 Gy exposures occur at 1350 m and 900 m. The lethal range for tactical neutron bombs exceeds the lethal range for blast and heat even for unprotected troops, which is likely the reasoning for the idea that a neutron bomb destroys life and not infrastructure. If a neutron bomb were detonated at the correct altitude, deadly levels of radiation would blanket a wide area with minimal heat and blast effects when compared to a pure bomb.

The neutron flux can induce significant amounts of short-lived secondary radioactivity in the environment in the high flux region near the burst point. The alloys used in steel armor can develop radioactivity that is dangerous for 24-48 hours. If a tank exposed to a 1 kt neutron bomb at 690 m (the effective range for immediate crew incapacitation) is immediately occupied by a new crew, they will receive a lethal dose of radiation within 24 hours.

One significant drawback of the weapon is that not all targeted troops will die or be incapacitated immediately. After a brief bout of nausea, many of those hit with about 5-50 Sv of radiation will experience a temporary recovery (the latent or "walking ghost phase") lasting days to weeks. Moreover, these victims would likely be aware of their inevitable fate and react accordingly.

In popular culture

Art and literature

  • In Richard Ryan's novel Funnelweb (1997), the Australian government negotiates for an American neutron bomb to be detonated in the city of Sydney to dispatch the infestation of enormous mutant spiders. However, the blast does not have any effect on spiders living beneath the ground, allowing these later, stronger generations of mutant spiders to take hold.
  • In 1979, artist Chris Burden created a piece of installation art called The Reason for the Neutron Bomb, which consists of 50,000 nickels with matchstick tips glued to them, arranged in tight rows across the floor of the gallery. It can be said to represent the 50,000-strong Soviet tank force at the time.

It is also referred to as a "clean bomb" due to the lack of long term radiation it is said to produce, of course they are detonating it in the middle of a city, but apparently the walls built around the district will stop any stray radiation from harming nearby Paris.
  • The character "J. Frank Parnell" in the 1984 film Repo Man mentions the neutron bomb in the course of justifying voluntary lobotomies: "Friend of mine had one. Designer of the neutron bomb. You ever hear of the neutron bomb? Destroys people - leaves buildings standing. Fits in a suitcase. It's so small, no one knows it's there until - BLAMMO. Eyes melt, skin explodes, everybody dead. So immoral, working on the thing can drive you mad. That's what happened to this friend of mine. So he had a lobotomy. Now he's well again." The DVD release contains footage of Alex Cox interviewing, then watching Repo Man with nuclear physicist Samuel Cohen, inventor of the W70 warhead. Cohen mentions it being one of his favorite films.
