Here's why:
* Gamma rays are the highest energy form of electromagnetic radiation.
* Nuclear processes like radioactive decay, nuclear fission, and nuclear fusion release energy.
* This energy is often released as gamma rays, which originate from the nucleus itself.
Other electromagnetic waves are generated by different processes:
* X-rays are produced when electrons are accelerated, often in the electron shells surrounding the nucleus.
* Visible light is emitted by the transitions of electrons between energy levels within atoms.
* Infrared radiation is associated with molecular vibrations and rotations.
* Microwaves and radio waves are generated by oscillating electric currents.
