Dear Fluka experts,

I try to verify the ambient dose equivalent using both USRBIN and USRBDX
CARD.

For the USRBIN CARD case, the USRBIN is set as scoring DOSE-EQ, AUXSCORE
is set as PHOTON-pass filter and AMB74 for SDUM column. The result is
considered as pSv/s and uncertainty with percentage.

For the USRBDX case, the USRBDX is set as scoring DOSE-EQ as well,
AUXSCORE is set as PHOTON-pass filter and AMB74 for SDUM column. The
result is considered as # of photon/GeV/cm2/s and uncertainty with
percentage. Ambient dose equivalent conversion factor is applied using
adeph.dat providing on the FLUKA website.

The final result is asked to present as Sv/hr. While the two different
cards lead to dramatic discrepancy. Am I misunderstanding the units or
anything toward the results?

Best and looking forward for your reply,
