Hi Susanna,

I appreciate your responding to my query. Thank you. As I am relatively new to Geant4 and do not have much of a frame of reference of all of its internal workings, I was somewhat uncertain on how to proceed in light of the results my simulation generated for the Brachytherapy example.

Although some photon 'leakage' is expected here in reality, the number of escaping gamma rays from the housing walls in the simulation seemed quite excessive when compared it to the total number of events generated. (extensive leakage is observer for large event number)

Are there any possible reasons you might have for this? In my simulation I have also modeled my applicator housing to factory specifications.

Thank you for any suggestions that you might have.

David Callender.
