BEAMnrc

BEAMnrc is a Monte Carlo (see Monte Carlo Method) code system for simulating radiation therapy sources. It 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. It is based on the EGS code system for the coupled transport of electrons and photons. BEAMnrc can model all types of medical linear accelerators, using the codes component module system.
