Hi Everyone. I am also a beginner for geant4.now I have some problems.I want to simulate one measure system's efficiency which uses a BGO crystal as detector. the source emits gamma ray,then gamma ray pass through a measured object,detected by BGO crystal .my question is how to calculate the system's efficiency? sould I consider the BGO 's scintillation? should I count all gamma ray pass through BGO,then divided it by the total incident gamma ray particles(this result is the efficiency?)? thanks for your help!!
