Hydrogen bomb

scroll

Nuclear weapon using the energy release of nuclear fusion reactions. Probably, the reactions ⁶Li (n,) ³H + 4.8 MeV and H (d,n)⁴He + 17.6 MeV are involved. An atomic bomb is used to fire the hydrogen bomb, i.e. to reach the temperature required for fusion. The explosion force achievable far surpasses that of atomic bombs, the destruction equivalent is that of several megatonnes trinitrotoluene, a chemical explosive. The first hydrogen bomb was fired on the Bikini Atoll on 1^st March 1954.
