Question

Backscattering does have dependencies on atomic number and on thickness. Does either one dominant the amount of backscattering versus the other? What kind of dependence do you predict for each?

Explanation / Answer

Yes, backscattering depends on both of the atomic number and thickness. No, Either one can't dominate the amount of backscattering versus the other. There was a direct relationship between them because the backscattering means how much ? particles scatters from a sample, so if the sample is thick enough the more ? particles will scatter from the sample, and which causes a rise of backscattering. On the other hand, the backscattering is directly proportional to the log(Z+1). Where Z is the atomic number. So the backscattering is directly proportional to the thickness and atomic no of the sample. That's why there is a direct relationship between them.
