What was wrong in the exponent? I have -(0.5 cm-1 x 1.3 cm) I don't know what else to do with the information given.

Bump.

Homework Statement Calculate the fraction of photons absorbed from an attenuated beam of 0.5 MeV photons after it has gone through 1.3 cm of lead? The linear attenuation coefficient of lead for 0.5 MeV photons is 0.5 cm-1. Why is lead a good choice as a material for shielding? Homework...

Attempt at the question: R(B) = [M/Z2] Rp(B) Propton range versus energy of photon values gained from this graph...

Hi, I can't really put my lecture notes on here - they're too long to post and it would identify the university. I've taken a screenshot of the section of the notes where those equations are from. It's a past paper question on the subject of radiaton protection. I don't have a book so any...

Homework Statement I've uploaded the question in the attached file. Homework Equations R ∝ 1/p R ∝ M/z2 The Attempt at a Solution I don't understand what is in my lecture notes. What equations do I need to attempt this question? Thank you.
