Abstract: After analyzing the advantages and disadvantages of Monte Carlo and deterministic methods for solving particle transport problems, a zero variance iteration scheme and a semi-random simulation method are presented, which exploits the strengths and discards the weak of both methods. Both the scheme and the method are described briefly.

Key words: semi-random simulation, Monte Carlo, radiation transport
