The experiment shoots a beam of 1.33 MeV gamma rays into a lead target.
a. Calculate the intensity of gamma rays (still in the beam) that make it through the lead. [10 pts]
b. What is the probability of a photon making it through the target without any interaction? [10 pts]
I0 = 9.4x10^12 gamma/cm^2 sec
x = 0.45 cm (thickness of lead)
I(x) = (Intensity after the beam goes through the lead)
