FLUKA software code is used by Epcard, which is a software program for simulating radiation exposure on airline flights.[https://books.google.com/books?id=_6hymYAgC6MC&dq=Epcard&pg=PA229 Jeffrey R. Davis, Robert Johnson, Jan Stepanek - Fundamentals of Aerospace Medicine (2008) - Page 228-230] (Google Books Link 2010)

The first version of FLUKA was developed in 1960s by Johannes Ranft. FLUKA makes use of combinatorial geometry.
