The photon is the elementary particle of Electromagnetic energy and represents quanta of energy. For Radiation Protection purposes they are represented by Gamma Rays and X-Ray Photons (Non-Ionising Radiation would, of course, include light Photons). They are taken to have no mass and no electrical charge.
Physics is really nothing more than a search for ultimate simplicity, but so far all we have is a kind of elegant messiness
