 Summary: This chapter is devoted to describing how Monte Carlo techniques based on simu- lation can be used to describe and quantify how neutral particles migrate through matter. Combinatorial geometry is used to describe the composition of the various regions of interest in a transport problem. Sampling of source emission directions and path length distances between interaction events is described. The effects of computer precision on tracking particles through the geometry is then discussed. The sampling of a particle’s energy and direction after a scattering event is explained. The use of particle weights and how they affect tallies is developed and…
