The methods to obtain the extinction coefficient and the scattering phase function are studied to solve radiative transmission through packed spheres by a continuous model. The validity of the methods is shown by comparing the results with the ones of direct Monte Carlo simulation. To obtain an effective extinction coefficient, a cell model which represents the extinction in a cell composed of a real-sized sphere and its surrounding volume should be used. To obtain an effective scattering phase function, non uniform radiation incidence to the surface of each sphere should be considered instead of using uniform incidence, and the non-uniform incidence onto each sphere surface can be obtained by considering that a real-sized sphere is set in a radiation field whose intensity from the entrance to the exit of the bed of the packed spheres.
