Modifications of the Planck blackbody intensity and emissive power are proposed due to the modifications of the photon energy transport velocity and the density of states in particulate media. These modifications result from the multiple scattering of photons. These modifications affect the heat flux and temperature predictions in particulate media. Results show that current methods of predicting heat flux and temperature can lead to erroneous conclusions in a multiple-scattering radiative system.
