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? (direct, inverse, inverse square for exampled- be descriptive)

Solutions

Expert Solution

  • 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.

The element technetium (atomic number 43) is radioactive and one of its isotopes, 99Tc, is used in medicine for diagnostic imaging. The isotope is usually obtained in the form of the pertechnetate anion, TcO4-, but its use sometimes requires the technetium to be in a lower oxidation state. Reduction can be carried out using Sn2+ in an acidic solution. The skeleton equation is TcO4- + Sn2+ → Tc4+ + Sn4+ (acidic solution) Balance the equation by the ion–electron method.
