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., @[email protected] and water purification through @[email protected]) dose is used in the sense of @[email protected], 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 @[email protected] and @[email protected] are preferred.
