At this dose rate, any unsheltered person exposed to the fallout would receive a lethal dose in about 30 minutes (assuming a median lethal dose of 5 Sv). These changes would reduce the explosive power ( yield) of the weapon somewhat.ДЄssume a cobalt bomb deposits intense fallout causing a dose rate of 10 sieverts (Sv) per hour. In a fusion bomb the radiation case around the weapon, normally made of 238U, could be made of cobalt. In a fission bomb, it has been suggested, the weapon's tamper could be made of cobalt. Many isotopes are more radioactive ( gold-198, tantalum-182, zinc-65, sodium-24, and many more), but they would decay faster, possibly allowing some population to survive in shelters. The 5.27 year half life of the 60Co is long enough to allow it to settle out before significant decay has occurred, and for it to be impractical to wait in shelters for it to decay, yet short enough that intense radiation is produced. Nickel-60 is a stable isotope and undergoes no further decays after emitting the gamma rays. The nickel nucleus is activated, and emits two gamma rays with energies of 1.17 and 1.33 MeV, hence the overall nuclear equation of the reaction is: The deposited Cobalt-60 would have a half-life of 5.27 years, decaying into 60Ni. The cobalt would then condense and fall back to Earth with the dust and debris from the explosion, contaminating the ground. When the bomb explodes, the neutrons produced by the explosion would transmute the cobalt to the radioactive isotope cobalt-60 ( 60Co), which would be vaporized by the explosion. Antimatter is alternative fusion trigger, mainly for antimatter-catalyzed nuclear pulse propulsion.A cobalt bomb could be made by placing a quantity of ordinary cobalt metal ( 59Co) inside a nuclear bomb. Due to its not requiring a fission primary explosive to initiate a fusion reaction, the pure fusion weapon also has greatly increased yield. A cobalt bomb's fallout would render affected areas stuck in fallout for decades.ДЄ pure fusion weapon is a hydrogen bomb that does not need a fission 'primary' explosive to ignite the fusion of deuterium and tritium. A fission weapon's fallout decays much more rapidly than that of a cobalt bomb. Fusion reactions do not create fission products, and far less nuclear fallout, but due to the fission stages, can end up creating the same fallout as fission weapons.ДЄ neutron bomb is a low-yield thermonuclear weapon designed to maximize lethal neutron radiation in the immediate vicinity of the blast while its neutron burst is able to penetrate enemy armor such as tanks more effectively than a conventional warhead.ДЄ cobalt bomb is designed to produce enhanced amounts of radioactive fallout, intended to contaminate a large area with radioactive material.

The energy yield can be up to 50 megatons of TNT. Fission reactions are used to trigger fusion reactions, and these fusion reactions can trigger additional fission reactions. This second generation rely on fusion reactions between isotopes of hydrogen (deuterium and tritium).

They are a serious form of radioactive contamination and nuclear fallout.ДЄlso called thermonuclear weapon, hydrogen bomb, H-bombs. The amount of energy released by fission bombs can range from about 1 ton to over 500 kilotons of TNT.

This first generation nuke uses fissile material, usually enriched uranium or plutonium. Nuclear non-proliferation treaties have to be signed by Type 0 civilizations in order to prevent MAD (mutually assured destruction) in a futile nuclear war.ДЄlso called atom bomb, atomic bomb, A-bomb. Nuclear devices are weapons of mass destruction (WMD) or doomsday devices and can devastate entire cities by blast, fire, and radiation. A few 1000 gigatons would be enough to kill all humans. Potential gigaton yield devices are 'doomsday bombs.' One detonated about 16 kilometers up would start fires over an area of more than 700,000 square kilometers. Its weight to energy yield ratio is more than 1:1000. Nuclear bombs have had yields between 10 tons and 50 megatons of TNT. Both bomb types release large quantities of energy from relatively small amounts of matter. A nuclear weapon (or nuke, nuclear warhead, nuclear bomb) is an explosive device that uses nuclear reactions, either fission (fission bomb) or from a combination of fission and fusion reactions (thermonuclear bomb).
