Question Neutron Flux 

Forum: Medical Applications

From: Aqsa <Aqsa>

I have written a simple program in which I need to obtain photon flux by hitting energetic electrons on a Tungsten target. In the program I have also added a detector for counting neutron flux. Since my photon energy will be crossing GDR I am expecting considerable amount of neutron production. When I compared the neutron yield obtained from my GEANT4 code to that of few theoretical formulae and experimental yield given in papers, I found that GEANT4 is giving much less neutron flux (In extreme cases as much as one order less) than expected from theory. I know that simulation codes tend to underestimate the yields but I am worried if one order less is too much of underestimate. Any suggestions?
