EGSnrc is a Monte Carlo code system for simulating radiation therapy sources. It is a fork of the EGS code system for the coupled transport of electrons and photons which incorporates BEAMnrc. BEAMnrc was developed as part of the OMEGA project, a collaboration between the National Research Council of Canada and a research group at the University of Wisconsin–Madison. All types of medical linear accelerators can be modelled using the codes component module system.
