Calculation of the radiation field in a dense medium by the Monte Carlo method

We consider the problem of calculating the characteristics of the scattered radiation field in an optically dense medium by the Monte Carlo method. Separating the delta -function from the density of free path, we transform a transport equation. This transformation results in the new density of modelling the trajectories. We give the obvious description of the computational method, which is based on studying the form of the trajectories of particles in an optically dense medium. The restrictions on the application of the method are given. In conclusion, we give the results of the numerical experiment on the comparative study of the efficiency of the method proposed and original calculations.
