Dear Amor,
Your cobalt source with HI-PROP seems correct.
For sure, using IRRPROFI card allows you to normalize the score with your cobalt source activity and time units.
You just have to convert the GeV.cm^3/g, as detailed by Francesco, in the unit of your choice.
Best regards,
Thomas Frosio

Subject: Re: [fluka-discuss]: Dose in a region
Hello,
First, I'm thankful to Francesco and Thomas for answering my questions. I attach my input if it could help you to answer my questions about dose per region.
Then, I would like to ask you about the way I'm defining the Cobalt source. Is it correct?
If I used then the IRRPROFI card, do I need normalize the score with the activity of my Cobalt source?
Kind regards,
Amor Romero

Hallo
the output of the USRBIN *per region* is NOT normalized by the region
volume, which is unknown to FLUKA, so, when you ask for DOSE, you will
rather get GeV cm^3/g per primary particle.
