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
