Nuclear Bombs (Atomic and Hydrogen Bombs):

* Yes: Nuclear bombs absolutely produce gamma rays. In fact, gamma rays are a significant part of the radiation released during a nuclear explosion.

* Mechanism: The fission and fusion reactions within the bomb release a tremendous amount of energy, including gamma rays.

Conventional Bombs (Explosives like TNT):

* No: Conventional bombs do not produce gamma rays. They rely on chemical reactions for their explosive power, which don't generate high-energy radiation like gamma rays.

Other Considerations:

* Neutron Radiation: Some nuclear bombs (specifically fission bombs) also release significant amounts of neutrons. These neutrons can interact with materials and produce gamma rays.

* Fallout: Nuclear fallout can also contain radioactive isotopes that emit gamma rays.

In summary:

* Nuclear bombs: Yes (and a major part of the radiation)

* Conventional bombs: No
