    Dear FLUKA users,

    I have a very fundamental and rather simple question that nobody seems
    to be able to answer. How do you correctly determine dose at the center
    of a solid aluminum sphere. I want to compare FLUKA 3D results with
    results from others codes, such as Shieldose2 and GEANT4.

    I've included a test input file as an example. The results from SCORE
    and USRBIN 1) don't agree with each other, then 2) they aren't even
    close to that from the other codes. Ultimately, I would like to get the
    dose at the center of a sphere from an isotropic source/spectrum (hence
    my source command at the bottom). For now, I am directing all energy to
    the center -- the answer should be relatively close to that from an
    isotropic source.

    Can any body help me determine dose in Rad or Gy at the center of a
    solid sphere --- and provide an answer that consistent with what is
    published in literature?

    Sincerely,

    Brandon
