But maybe I have misunderstood something ? Cheers Philippe From: owner-fluka-discuss_at_mi.infn.it [mailto:owner-fluka-discuss_at_mi.infn.it] On Behalf Of Masoomeh Yarmohammadi Satri Sent: Tuesday, June 13, 2017 3:06 PM To: fluka-discuss_at_fluka.org Subject: [fluka-discuss]: Fluka run and calculation comparision Dear All, I exposed a two layers: Titanium-copper target with a 10MeV electron beam and read the Dose equivalent data at 1m from the target before a 30cm Concrete wall and after the wall. For a cross check, I used the D2=D1 exp (-ux/p) and implemented the D2 (Dose EQ after the 30cm concrete wall) and D1 (Dose EQ before the wall) from the fluka run data (file is attached as a png). I was expecting the x=30 cm but solving the relation for x gave x=103cm concrete thickness. Could you please let me know why this big difference between the relation and simulation while data of simulation is extracted from 30cm concrete wall thickness?
