About half of the output of a big thermonuclear device is produced by the fission of depleted uranium.ĭespite obvious signs (as early as 1944) that they had little prospect of prevailing, Japan had signalled that they were willing to fight to the final end in the Pacific. In a hydrogen bomb, the energy created during a fission reaction is used to heat and compress the hydrogen in order to start a fusion reaction, which can then lead to more fission reactions. This is usually achieved through the use of deuterium and tritium (two hydrogen isotopes) that fuse to provide energy. ![]() Hydrogen bombs, or H-bombs for short, are also a type of nuclear weapon, which detonate as a result of the enormous energy produced by nuclear fusion. When detonated, fission fragments make up the majority of nuclear fallout. Additionally, radioactive fission fragments are released by the bomb as a result of the heavier nuclei splitting into smaller ones. Atomic bombs are measured in kilotons, with each unit equal to the explosive force of 1,000 tons of TNT. The atomic weapon which leveled Hiroshima in 1945 had a yield of around 15 kilotons or the explosive power of 15,000 tons of TNT.Ī single atomic bomb can produce between around a ton and 500 kilotons of the explosive TNT. The fission reaction is incredibly powerful. This material usually consists of either enriched plutonium or enriched uranium. Because of this, this kind of bomb is also often referred to as a fission bomb.Ī material capable of fission (fissile material) is given supercritical mass, which is the point at which fission occurs - the nuclear breaks apart. This can be done by either firing one portion of a sub-critical mass into another or by compressing the sub-critical material with conventional explosives. To better understand this, it is probably worth giving a quick overview of each.Īn atomic bomb, or A-bomb for short, is a form of nuclear weapon that detonates as a result of the tremendous energy unleashed by nuclear fission. In other words, a hydrogen bomb is set off by an atomic bomb. In essence, a hydrogen bomb employs fission to fuel a fusion process, whereas an atomic bomb is solely a fission-based weapon. ![]()
