Actinic
Definition
Relating to radiation or luminous flux; capable of producing intense chemical (and photochemical) changes or reactions in the substances it strikes or traverses. Actinic properties are characteristic primarily of ultraviolet spectrum radiation and short-wave solar rays, being essential in the exposure process of conventional photographic emulsions or in triggering biological phenomena within living tissues.
