so just about finishing a report on x ray abosprtion on different materials, generally the linear attneuation coefficent increases with atominc number Z. However silver(47) had a lower attenuation coefficent then zirconium(40) despite having the significantly higher value of Z.
With some reading found that the absorption edges ;where there is a rapid increase in absorption from photon matching the binding of a shell, depends on the energy of the x ray your using. So we thought this must explain our result with silver. Looking at the K shell :
Zirconium has Kedge absortpion at 18KeV
Silver has kedge absorption 25 KeV
Our supply voltage was 35Kv---> 35KeV , so why does zircmonium have more absortion?
