Okay, you asked. A neutron bomb is a weapon designed and constructed specifically to deliver a large(r) dose of radiation over a broad area to increase the lethality of the we…apon without an increase in blast damage. Be clear that there will be A LOT of blast damage; it's a nuclear weapon. But the bomb is designed and constructed to produce more radiation. It's called a neutron bomb for the reason that there is a gross generation of "extra" neutrons. Because neutrons have no charge, they penetrate matter better than a hot knife through butter. Neutrons only minimally react with electrons (once in a very great while a neutron will slam into one), so that leaves collision with an atomic nucleus as their primary means of slowing down. The collisions (skip all the scattering and recoil stuff) directly ionize materials and/or create radiation which will in turn ionize stuff. The neutrons do direct damage to things when colliding, but the secondary effects do a tremendous amount of damage, too. Organic molecules (the stuff people are mostly made out of) take heavy damage from the effects of ionizing radiation. The radiation breaks the covalent bonds of biochemical substances (that make up living things) in a wholesale manner. Radiation is the bull in the china shop.. The bomb is actually a fission fusion device. There is a primary stage in which a conventional chemical explosive is set off. The specially shaped charges (explosive lenses) are placed precisely around the fissionable material to drive it together. The shock wave compresses the heck out of the subcritical masses of, say, plutonium-239. Begin secondary stage: the fission of the plutonium. The fissile material goes critical. The chain of fission, neutron release and further fissions becomes self sustaining. But hold the phone. Everything is still moving "in" here. Recall the explosive lenses? The chain goes instantly through criticality to supercriticality. Neutron production goes through the roof and the nuclear burn is ramped up. Something like deuterium is added to the center, and when the fission stage lights up, the heat initiates a tertiary stage that is fusion. Neutron flux is extremely high, but materials have been selected for composition and given a geometry (contour) to allow a whole bunch of the neutrons to escape instead of building the chain further. That makes for the "enhanced radiation" part of the "enhanced radiation weapon" as the bomb is sometimes called. There is a blast like you have never seen. (Again, it's a nuc; there will be a lot of blast damage.) But radiation production is maximized.. The extra radiation is designed to slam through things like tank armor. Kill or disable the crew and you've put the tank out of action. And this radiation is very lethal to tank crews that may think they've survived the blast because of the armor of the vehicle. The lethality of the weapon to those buttoned up inside a tank was the primary thinking behind development of the bomb. Back in the day, the USSR had NATO way outgunned in the tank department. The number disadvantage was severe. We needed an edge. But times have changed. The weapons have been stricken from the US inventory and are (probably) no longer a part of strategic planning.

Credit to this invention usually goes to Lawrence Livermore Lab's Samuel Cohen in 1958. The ERW was tested in 1963. Development was halted by President Carter in 1978 and rest…arted by President Reagan in 1981. Some weapons were retired in 1992 by President George Bush. The last warhead was dismantled in 2003.
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 Pres…ident 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.
The Controllers' "Neutron Bomb" begins with a poem from WWII about a disemboweled gunner on a bomber over Europe. Then it goes: Some people think atomic bombs are weird … But I don't want to end up seared By the Neutron Bomb Very strange! By the Neutron Bomb Cold War exchange! I can't get up Might get blown up Neutrons falling down Might as well hang around For the Neutron Bomb . Try heading over to www.lyrics.com and search "The Controllers" and see if the band and song come up.. If that doesnt work, try searchng the artist and song name on google (:
The United States was the first country to develop the neutron bomb or "Enhanced radiation weapon" first testing a device in 1963.
The U.S. did
No country is known to currently have neutron bombs. The concept was developed in the US in the early 1960s (and some testing along those lines was done by, at least, the US …and France in the mid-1960s), and France actually tested a full neutron bomb in 1980.
us . Yes, the United States was the first to develop a Neutron bomb, it was originally part of the United States efforts following the fallout problems with the 1954 Castle B…ravo test (15Mton) to develop a low fallout or " clean " Hydrogen bomb. In a standard Hydrogen bomb typically 90% of the yield and fallout is produced by fission of the depleted uranium tamper by the high energy fusion neutrons from the compressed hydrogen fuel assembly fusing. If one were to replace the depleted uranium tamper with one made from an element almost as dense as uranium, non-fissionable, and transparent to the high energy fusion neutrons (e.g. lead); then at some loss of yield one could eliminate almost all the fallout of a Hydrogen bomb! The fact that such a " clean " Hydrogen bomb would emit a very high local high energy neutron flux was not even considered at the time, just the reduction in fallout. The first such " clean " Hydrogen bomb was tested in the 1956 Redwing Zuni test (3.5Mton) had a yield that was only 15% fission with a similar reduction in fallout. The nearly identical standard Hydrogen bomb the 1956 Redwing Tewa test (5Mton) had a yield that was 87% fission. A second, different, " clean " Hydrogen bomb was tested in the 1956 Redwing Navaho test (4.7MTon) had a yield that was only 5% fission! It was first realized in 1958 by Sam Cohen at LLNL that further changes (e.g. more neutron transparent tamper, high efficiency hollow core tritium gas boosted fission trigger) could produce a weapon generating more of its yield as neutron radiation than as blast (this was first tested underground in Nevada in 1963). After long years of debate over the potential advantages/disadvantages of " clean " vs. standard vs. " dirty " (aka " salted ") Hydrogen bombs, both " clean " and " dirty " designs were abandoned because of the lost yield for the same usage of expensive nuclear materials. The " clean " Hydrogen bomb returned (with some design changes, see above) in the middle 1970s, but now renamed the Neutron bomb or ERW (Enhanced Radiation Weapon). Carter delayed deployment, Reagan deployed it, Bush withdrew it. Do not confuse a dirty radiological bomb with a " dirty " Hydrogen bomb. The radiological bomb is just an ordinary chemical explosive wrapped in highly radioactive isotopes, which it disperses when it explodes. Such a bomb will probably kill everyone involved in assembling it before it affects anyone at its target. A " dirty " Hydrogen bomb uses a tamper made of a material that captures neutrons and transmutes into highly radioactive isotopes, increasing the fallout.
A neutron bomb, or enhanced radiation weapon (ERW), is a type of tactical nuclear weapon designed specifically to release a large portion of its energy as energetic neutron ra…diation rather than explosive energy. Neutron bomb would use nuclear fusion, but in a different way. The detonation of a neutron bomb would still produce an explosion, but one much smaller than a standard nuclear weapon's. The main effect of a neutron bomb would be the release of high-energy neutrons that would take lives far beyond the blast area. The result: fewer buildings, cars, tanks, roads, highways and other structures destroyed.
It is not. A "smart" bomb is one with a guidance system that guides it directly to the target. A "Neutron" bomb is a specialized form of nuclear weapon that produces relativel…y little blast, but releases more immediate nuclear radiation than most other nuclear weapons
In World War 2
The atomic bombs were dropped by the Americans from a plane onto Hiroshima and Nagasaki to end World War Two on August 6th 1945 (Hiroshima,Little Boy) and August 9th 1945 (Nag…asaki,Fat Man) They were used because Japan were really the only remaining opponent (The Nazis had already surrendered), And Guess what ! It Worked!

"Enhanced radiation" weapons, including the 'neutron bomb', havebeen stricken from the US inventory and are (probably) no longer a part ofstrategic planning.
In Nuclear Weapons
A neutron bomb is a type of hydrogen bomb. It actually was adevelopment that came from the late 1950s work by the US to make"clean hydrogen bombs" that produced very little fa…llout. In a conventional hydrogen bomb the tamper (device to contain thenuclear reaction as long as possible to get as much energy from itas possible) is usually made with depleted uranium because of itshigh density and low cost. While depleted uranium will not supporta neutron chain reaction it will fission when hit by the highenergy neutrons produced by the fusion reaction of the hydrogenbomb. This depleted uranium fast fission can produce up to 90% ofthe total yield in some hydrogen bomb designs, as well as aproportional amount of the fallout. In a "clean hydrogen bomb" the tamper is instead made of some othervery dense metal that unlike uranium will not fission when hit byhigh energy neutrons. Lead and tungsten have been used. However theexplosive yield of a "clean hydrogen bomb" will be lower than asimilar conventional hydrogen bomb because there is no fission inthe tamper. But as these materials do not consume the high energy neutrons,they escape from "clean hydrogen bombs". It was observed that theseneutrons easily pass through tank armor and building walls, killingthose inside while the lower yield produces less blast and firedamage. Thus was born the idea of the neutron bomb.
In Nuclear Weapons
A neutron bomb is a form of nuclear weapon. It explodes in several steps. In the first step, control circuits fire electronic blasting caps cause conventional explosives to de…tonate. They are shaped in such as way that the explosion crushes a ball of nuclear material (mainly plutonium) causing that to produce nuclear fission (an atomic explosion). THAT serves as the trigger to a nuclear fusion explosion- (similar to the hydrogen bomb). This releases heat, blast, and neutrons.
In US in WW2
Neutron bombs are designed to release massive amounts of radiation but not leave behind high levels of long-term radiation. Specifically, it is engineered to release much of i…ts energy as fast-neutrons (hence the name for the device) rather than explosive energy. The high level of neutrons released during detonation is intense enough to penetrate buildings, people, and even moderate armor - disrupting living cells to such a degree that death will follow within a few days for those exposed. The neutron bomb was developed primarily as an anti-armor weapon - to penetrate tank armor and kill their crews for example. Modern tank armor is now sufficiently heavy to reduce the exposure of the crews to levels such that in order to get enough radiation through the armor, the device would have to be detonated so close to a tank that the blast effect (heat and blast pressure) would be just as much a factor as the radiation, so most neutron weapons have been dismantled and disposed of as obsolete.
