THERMO NUCLEAR WEAPON:
See “hydrogen bomb”
A nuclear weapon detonated in the air to maximise destructive capabilities. Since the blast comes from above, it is less contained by buildings around it.
When a nuclear explosion occurs at ground level, the blast blows bits of dirt and debris into the air, where they become radioactive and are carried by the winds before falling back down to Earth.
The destructive power of a nuclear weapon.
A bomb powered by nuclear fission, the splitting of atoms. Most atomic bombs are rated in kilotons – each of which is the equivalent of 1 000 tons of TNT.
A nuclear weapon detonated on the ground. It causes less widespread destruction than an airburst but releases fallout.
A missile that can travel thousands of miles by exiting Earth’s atmosphere, hitting suborbital space, and re-entering the atmosphere. Most commonly used in the delivery of nuclear weapons.
Also called a thermonuclear weapon, this type of bomb is much more powerful than an atomic bomb. It’s actually set off by an atomic bomb, and gets its power from the resulting nuclear fusion, the combining of atoms. Most hydrogen bombs are rated in megatons, the equivalent of 1 000 kilotons.
Air currents over a particular area that typically flow in the same direction.
