Find the number of gas molecules ionized when one electron enters the GM tube (1MeV = 10°eV).

The source of gamma rays is radioactive cobalt, which reliably produces photons with E the 1.17 MeV.

What will be the photon's energy E' after the scattering event (in the units MeV)? Draw a be- fore/after diagram for the photon-electron collision, and make sure that your sketch conveys the idea that momentum is con- served.
