Interactions With Matter

  Alpha and Beta Particles

–Energy Loss Method

a) collision

b) radiative (coulomb interactions)

                                        Emax

Beta Range (g/cm2) ~  ----------

                                            2

Rule of Thumb:  Beta Range in Air ~ 12 ft / MeV
