Distance
Distance, in the context of Radiation Protection
, relates to one of the three key principles of protection against External Radiation
hazards (i.e. Time
, Distance & Shielding
). In simple terms, increasing the distance between a static source of Ionising Radiation
and the absorbing medium (e.g. a person) will reduce the exposure to that person. For certain defined geometries, (e.g. Point Source
), the Inverse Square law
can be applied which can be stated as: 'double the distance, quarter the dose'.
