dose

https://doi.org/10.1351/goldbook.DT07361
Energy or amount of photons absorbed per volume (or per mass) by an irradiated object during a particular exposure time. SI units are \(\text{J m}^{-3}\) or \(\text{J g}^{-1}\) and \(\text{mol m}^{-3}\) or \(\text{mol g}^{-1}\), respectively. Common units are \(\text{einstein m}^{-3}\) or \(\text{einstein g}^{-1}\), respectively.
Note:
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.
