[fluka-discuss]: CT scan dose equivalent scoring

Dear FLUKA experts,

I'm trying to get the total dose equivalent in pSv deposited in a CTSCAN
voxel geometry using the USRBIN card produced from the DICOM tool in
flair. My source is a sphere of alpha particles of 6.48MeV isotropic.

When looking at the output file, stars are created but no dose appears
recorded in the voxels and no integrated dose over the volume appears in
the output either. Nevertheless, when I plot the fort 99 file using Flair's
Plot tab the dose map is created with no issues and a maximum, minimum and
integral value are also calculated to be 0.029 pSv/primary and cm3. This
dose appears extremely low to me.

Also, no stars are recorded when I try to perform smaller runs, such as
1000 primaries for example.

Flair's output shows no anomalies and the .err file after the simulation is
finished only shows the amount of stars produced.

Thanks so much for your help
