A neutron bomb, officially defined as a type of enhanced radiation weapon (ERW), is a low-yield thermonuclear weapon designed to maximize lethal neutron radiation in the immediate vicinity of the blast while minimizing the physical power of the blast itself.
A neutron bomb is actually a small thermonuclear bomb in which a few kilograms of plutonium or uranium, ignited by a conventional explosive, would serve as a fission “trigger” to ignite a fusion explosion in a capsule containing several grams of deuterium-tritium.

Mar 1, 2022 · The process of capturing the neutron and splitting happens very quickly, on the order of picoseconds (0.000000000001 seconds). In order for these properties of U-235 to work, a sample of uranium must be enriched; that is the amount of U-235 in a sample must be increased beyond naturally occurring levels. Weapons-grade uranium is composed of at ...
As an anti-missile weapon, enhanced radiation weapons can intercept and damage the electronic components of incoming warheads with the intense neutron flux generated upon their detonation. Cite this Article. Learn what a neutron bomb is, how it works, and about a neutron bomb's strategic uses.
The fission process becomes self-sustaining as neutrons produced by the splitting of atom strike nearby nuclei and produce more fission. This is known as a chain reaction and is what causes an atomic explosion. When a uranium-235 atom absorbs a neutron and fissions into two new atoms, it releases three new neutrons and some binding energy.
Higher neutron emission rate: – For Nagasaki-type design, even if neutron starts reaction at worst possible moment, “fizzle yield” is ~ 1kt – roughly 1/3 destruct radius of Hiroshima bomb – more neutrons won’t reduce this – Some advanced designs are “pre-initiation proof” Higher heat emission:
