- Gamma rays are light (photons), not particles. They have the highest frequency and shortest wavelength on the electromagnetic spectrum. Mostly, gamma radiation results from nuclear reactions.

Gamma rays have characteristics identical to X-rays of the same frequency—they differ only in source. Gamma rays are usually distinguished by their origin: X-rays are emitted by definition by electrons outside the nucleus, while gamma rays are emitted by the nucleus.
Gamma rays. These are all forms of radiation with energies much higher than visible light. X-rays and gamma rays have enough energy that during interaction with atoms, they can remove electrons. This causes the atom to become charged or ionized. That's why we refer to this as ionizing radiation.
A sample of gamma ray-emitting material that is used for irradiating or imaging is known as a gamma source. It is also called a radioactive source, isotope source, or radiation source, though these more general terms also apply to alpha and beta-emitting devices.
Oct 21, 2024 · The entire electromagnetic spectrum, from the lowest to the highest frequency (longest to shortest wavelength), includes all radio waves (e.g., commercial radio and television, microwaves, radar), infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
