$L_{\text{p}\text{,}t}={\displaystyle \underset{\Delta t}{\int }{L}_{\text{p}}\text{d}t}$

Note 1 to entry: The corresponding radiometric quantity is "radiance dose". The corresponding photometric quantity is "luminance dose".

Note 2 to entry: The photon radiance dose is expressed in metre to the power minus two per steradian (m⁻²·sr⁻¹).
