Dear Experts,
I am currently working on calculating the air kerma from an X-ray source based on a measured spectrum taken at a distance of 30 cm. However, I’ve encountered a discrepancy of approximately 10% when comparing my calculated air kerma to the experimental values.
I have a couple of questions regarding the simulation:
-
Should I set the production cutoff for electrons to 1 keV? I intend to ensure that electrons can be generated within the scoring volume. By implementing a higher transport cutoff, they would deposit their energy in line with the kerma definition.
-
what should be my transport cut-off if my max energy is 60 keV? Can I set 1 Mev as all will deposit??
-
Would lowering the electromagnetic field fix (EMFFiX) significantly impact my results?
I have attached the relevant inputs for your reference. I would greatly appreciate your insights or any suggestions if I am overlooking something in my calculations.
Thank you for your assistance!
