## Homework Statement

662 keV photons are emitted as a result of the decay of Cesium 137. These photons undergo Compton scattering.

What is the minimum energy of a Compton scattered photon? What is the maximum Compton electron energy? What is the range (cm) in tissue of a Compton electron that has maximum energy?

## Homework Equations

Range in (g/cm^2), R = o.412 T^(1.27-0.0954lnT), where T is the electron kinetic energy in MeV. The density of soft tissue is equal to 1g/cm^3.

## The Attempt at a Solution

I'm totally stuck.
