Question Scoring e- without scoring backscattered

Hi everybody,

I am scoring the number of particles through a cylindrical volume (shielding) to ensure that no beta particles pass through it. I am using G4PSPassageCellCurrent to check that out but unfortunately I've noticed that backscattered e- are taken into account. I've seen in the documentation that a second parameter can be added to G4PSPassageCellCurrent, which a depth. I though it could solve the problem by specifying the depth a particle as to cover but no. If I put depth to 1.*mm it does not change anything and if I put to to 1.*cm, nothing at all is scored (even with gamma that I used to check the correctness of the method).

I am thus wondering, what does the "depth" parameter stand for ? And most important, if the parameter cannot help me that way, how can I count beta particles that goes through a volume without counting backscattered electron ?

Big thanks in advance,
