Monte-Carlo based contamination modeling using GEANT

This paper describes the power of leveraging radiation modeling software to quickly construct direct simulation Monte-Carlo models. The radiation modeling code, GEANT, provides not only the framework to develop models with complicated geometries, but it gives one control over particle kinematics and propagation. An obvious added benefit to this approach is that the same model used for contamination analysis can also be used to perform radiation studies. Results of a simple model are presented followed by a discussion of the full potential of this approach.
