662 keV photons are emitted as a result of the decay of 137Cs. These photons undergo Compton scattering.(i) What is the minimum energy of a Compton scattered photon?(ii) What is the maximum Compton electron energy?(iii) What is the range (cm) in tissue of a Compton electron that has maximum energy?Range (in g/cm2), R=0.412 T(1.27 - 0.0954lnT), where T is the electron kinetic energy in MeV.The density of soft tissue is equal to 1g/cm3.
