I hope to receive assistance from experts, scholars, or official personnel! I previously read a FLUKA article titled “Overview of Fluence-to-Effective Dose and Fluence-to-Ambient Dose Equivalent Conversion Coefficients for High Energy Radiation Calculated Using the FLUKA Code.” The article mentioned that the website “http://www.fluka.org/DoseCoeff/” provides data files related to Fluence-to-Ambient Dose, but this URL is now invalid. Is there any way to find these Fluence-to-Ambient Dose data files?
Dear YunPeng,
The fluence-to-dose conversion coefficients used in FLUKA v4 are described in the following documents:
-
For quantities described in ICRP 116 see:
https://cds.cern.ch/record/2861988/files/CERN-OPEN-2023-009.pdf -
For the older quantities in ICRP 74 see:
https://flukafiles.web.cern.ch/flukafiles/documents/deq2.pdf
Cheers,
David
Thanks David！
I have read the literature you provided, and I would like to know if the deq99.f file mentioned in the literature contains detailed “fluence-to-dose” coefficients. If so, how can I obtain this deq99.f file? I could not find it in the FLUKA folder. Additionally, I would like to know how FLUKA calculates the ambient dose equivalent for protons. I noticed in the literature that ICRP does not provide dose equivalent conversion coefficients for protons, and I also could not find any information in the user manual on how FLUKA performs this calculation for protons.I am looking forward to your reply.
Cheers,
YunPeng
Dear YunPeng,
The def99.f user routine is not distributed anymore, since it is now incorporated into FLUKA.
The conversion factors were calculated with FLUKA simulation using anatomical phantoms for effective dose and the ICRU sphere for the ambient dose (equivalent). This was initially done by M. Pelliccioni for ICRP 74, and published in the paper you mentioned.
Cheers,
David
