Re: [fluka-discuss]: Normalization of results for x-ray tube output / source.f

Hi Alex,

If you take the function photons(E) that you plot in “spektasjpg.jpg’ and you compute <photons> = INT_{Emin,Emax}(photons(E) x dE) / (Emax-Emin), this will tell you how many photons/mm^2 in average you will produce per mAs of current for your x-ray source.
So, for a long enough simulation, you could just multiply the usual fluka normalization by that number:
(pSv/primary) x (photons/mAs) -------> (pSv/mAs) because primary=photons

of course this assumes that in your sampling ‘source.f’ routine you haven’t biased the weights of the starting photons.

Subject: [fluka-discuss]: Normalization of results for x-ray tube output / source.f

Dear experts,

I have made a test simulation but now I am not sure about the correct way to normalize the results.

I generated x-ray spectrum sample with SPEKTR 3.0 software, and using the help provided in this forum I was able to use modified source.f routine to re-create the beam and score the dose. I understand that that I get effective dose in pSv / primary. My question is what would be the correct approach to convert pSv/photon to pSv/mAs (x-ray Milliamp Seconds). Any comment / insight would be help,
