Electromagnetic and ),
Electromagnetic radiation is a particular form of the more general electromagnetic field ( EM field ), which is produced by moving charges.
Electromagnetic radiation composed of photons that carry minimum-ionization energy, or more, ( which includes the entire spectrum with shorter wavelengths ), is therefore termed ionizing radiation.
