Summary of MCNPX tally related to medical physics

(1) Absorbed dose calculation
f6:e (MeV/g) (MCNPX only, MCNP5 do not provide this option)
f8:p (MeV) (equivalent to Type 3 mesh tally with “TOTAL” option) e.g. rmesh1:p pedep (MeV/cm3)

(2) KERMA calculation (with KERMA approximation)
f6:p (MeV/g) (equivalent to Type 1 mesh tally with “PEDEP” option) e.g. rmesh3 total (MeV/cm3)

Mesh tally (MeV/cm3) should be multiplied by density (g/cm3) to get dose.
