While the Helmholtz coils in the e/m experiment handily bend a beam of
electrons, I believe that their field would be much too weak to bend (the
much more energetic?) beam of electrons emitted from radioactive source,

Wouldn't Helmholtz coils be a better choice for this purpose? They
would give you a larger, uniform field inside the chamber, as opposed to a
magnet which has a limited field...
