Dear Tolga

Regarding scoring particle fluence with USRBIN please see p.16 in the
lecture on scoring

https://indico.cern.ch/event/694979/contributions/2927109/attachments/1657642/2654312/Scoring_2018.pdf

in the given example replace NEUTRON by PHOTON and adapt the scoring mesh
according to your problem (e.g., bin size or instead of cylindrical mesh
an rectangular mesh). Note, by default this scores only prompt photons,
i.e. not including those from radioactive decays. If you want to include
them see the Manual for the DCYSCORE card (activate RADDECAY with WHAT(1)
> 1.0 and DCYSCORE with WHAT(1) = -1)

The second part of your question is not fully clear. Are you intested in
dose eq and fluence from prompt radiation or radioactive decays? Dose eq
from prompt radiation are scored, very similar to fluence, e.g. with
USRBIN and (generalized) particle type "DOSE-EQ. Regarding dose eq and
particles from decay radiation note that by defining negative cooling
times with DCYTIMES you can go back to any moment during your irradiation.
See for example p.5 in the lecture on activation

Hope that helps,

Cheers
Stefan
