External Radiation
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.
