IUPAC definition : Energy or amount of photons u absorbed /u per volume (or per mass) by an irradiated
object during a particular exposure time. SI units are J m-3 or J g-1 and mol m-3
or mol g-1, respectively. Common units are einstein m-3 or einstein g-1, respectively.;
Scope note : in medicine and in some other research areas (e.g., photopolymerization and water
purification through irradiation) dose is used in the sense of exposure, i.e., the
energy or amount of photons per surface area (or per volume) impinging upon an irradiated
object during a particular exposure time. this use is not recommended. the terms photon
exposure and radiant exposure are preferred.;
