Energy or amount of photons absorbed
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.
In medicine and in some other research areas (e.g., @P04648@ and water purification through @I03255@) dose is used in the sense of @ET06811@, 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 @P04632@ and @R05042@ are preferred.
