The main interest was taken in the effects of the density distribution on the radiation transfer in the scattering media. The frost layer in the early growth stage under the control of diffusion was chosen as the media. Numerical analysis of the radiation transfer was carried out by using a modified Monte Carlo method on the basis of the geometrical optics. A diffusion limited aggregation theory was introduced to simulate the growth of frost layer with treelike structure. The relation between the density distribution and the transmittance of the simulated model was made clear by the numerical analysis. On the basis of its result, the optical measurements in the visible wavelength region were utilized to evaluate the density distribution in the frost layer, which varied with the cooling condition, from the transmittance values.
