Dear Raushan Kabytayeva
Although your electron energy is low and you mention that you compare only photon dose, I suggest to add a LAM-BIAS card to bias photonuclear reactions (I see that you have a PHOTONUC card in your input), see also Note 2 for the PHOTONUC card in the manual
LAM-BIAS 0.0 0.02 18.0 7.0 0.0 0.0
Then it depends really on where and how you measure when you compare to simulated effective dose. I don't think a general recipe can be given. For a careful simulation of well-controlled setup and of the quantity measured a difference of a factor of 3 sounds a bit much...
Cheers
Stefan

Subject: [fluka-discuss]: FLUKA radiation protection
Dear FLUKA experts,
I am interested in calculations of electron accelerator equivalent dose from photons .
There is an idea about one experiment, but with a high intensity=10 microA(6E13eleactrons per second) And now we need to know is it reaaly with this protection of electron accelerator.But I have problem, FLUKA results are differs from dose measurement experimentally about 3 times for one point of measurement and about 1.5 times for the second point. There is no mistakes in geometry, I checked it and I think that there is no problem with code and normalise(USRBIN DOSE-EQ I normalise like this: FLUKA USRBIN Dose-EQ RESULTS *3.6E-3*6E13= microSv/h). Is it true?
if there are no errors in the code, I would like to know if anyone has encountered this type of problem and what is the prediction of the calculations for this case...
I'd be grateful if someone would point me towards the origin of the
problem. I'm appending my input file
