Hi,
Please take a look at the FLUKA manual, where it explains the source of implemented conversion coefficients in FLUKA:
SDUM : For dose equivalent (DOSE-EQ) scoring, the user can provide
the energy dependent factors for the conversion of fluence
to effective dose and ambient dose equivalent for neutrons,
protons, charged pions, muons, photons and electrons.
[Roe06,Pel00]
Default: AMB74
The following dose conversion coefficients sets are available:
1) Effective dose sets from ICRP74 and Pelliccioni data
calculated with ICRP radiation weighting factors Wr
(a) EAP74 : Anterior-Posterior irradiation
(b) ERT74 : Rotational irradiation geometry
(c) EWT74 : WORST possible geometry for the irradiation
2) Effective dose sets from ICRP74 and Pelliccioni data
calculated with the Pelliccioni radiation weighting
factors Wr
(a) EAPMP : Anterior-Posterior irradiation
(b) ERTMP : Rotational irradiation geometry
(c) EWTMP : WORST possible geometry for the irradiation
3) Ambient dose equivalent from ICRP74 and Pelliccioni data
(a) AMB74
4) Ambient dose equivalent with old "GRS"-conversion factors
(a) AMBGS
Default (DOSE-EQ scoring and option AUXSCORE not given): AMB74
