Edward Teller as he sought to develop a fusion weapon
, the hydrogen bomb.
For example, "pure" fusion weapon
research, aimed at achieving a nuclear explosion without the use of plutonium or uranium, is now being actively pursued.
By paying smart people to work on fusion energy "problems," we are inviting the possibility that a future Oppenheimer might one day invent a pure fusion weapon
requiring only small amounts of deuterium and a suitable detonator.
For larger fusion weapons
, the lethal area for the initial nuclear radiation is smaller than the lethal areas for blast and thermal flash, for the 1Mt bomb described above, about 22[km.
