Why is a particle's contribution to the flux in G4PSCylinderSurfaceFlux divided by the cosine of the incident angle of the track ?
In principle, I think that, conceptually, in this class one is sitting across a surface and simply counting how many particles are stepping through the surface in. Therefore, I think that each particle should simply be counted as one (multiplied by the weight, clear), indipendently from the direction the particle crosses the surface with. Can anybody give me a conceptual explanation of this ?
I have modified G4PSCylinderSurfaceFlux, multiplying each particle's contribution to the flux with an energy-dependent fluence-to-ambient-dose-equivalent coefficient (from ICRP 74) in order to get the ambient dose equivalent H*(d) and I worry that the results could be wrong because the way the flux is tallied is not convincing.
