gamma radiation is both a type of nuclear radiation and electromagnetic radiation.
Radiation has both electric and magnetic fields and travels in waves. It comes from natural and man-made sources. The intensity of electromagnetic radiation varies from low energy to high energy. There are radio waves, microwaves, infrared rays, visible rays, ultraviolet rays, X-rays, and gamma rays.
Electromagnetic radiation consists of an electric field (E) of varying strength perpendicular to the direction of propagation of the radiation and a magnetic field (M) perpendicular to the electric field. Both fields move at the speed of light (c).
Electromagnetic radiation occurs when atoms absorb energy. The absorbed energy causes one or more electrons to change positions within the atom. Electromagnetic waves are generated when electrons return to their original positions.
