The external radiation (hazard) exists where an absorber (typically a person) is being exposed to a source of Ionising Radiation external to the body. Examples would include exposures to Sealed Sources, dental X-Rays and Cosmic Rays. One feature of this hazard is that moving the absorber away from the source (usually) results in a reduction in the Dose of ionising radiation to that absorber, which is not the case for Internal Radiation hazards.
Physics is really nothing more than a search for ultimate simplicity, but so far all we have is a kind of elegant messiness
