Type B uncertainty … code
➢
What MC code should I use? / Should I prepare my own?
➢
Codes benchmarked and extensively used in the literature:
PTRAN, MCNP, GEANT4, PENELOPE, and EGS.
➢
TG-43U1*: Monte Carlo codes not previously used in brachytherapy dosimetry,
should be more rigorously tested and documented in the peer-reviewed literature
before proposing to use their results clinically.
➢
TG-43U1*: “regardless of the transport code chosen and its pedigree, all
investigators should assure themselves that they are able to reproduce previously
published dose distributions for at least one widely used brachytherapy source
model. This exercise should be repeated whenever new features of the code are
explored, upon installing a new code version, or as part of orienting a new user.”
