There are two ways to generate Beta particles:

i) Use G4GeneralParticleSource. In this you need to work out the beta spectrum distribution and histogram it first. you then import this distribution into G4GeneralParticleSource.

or 
ii) Add G4RadioactiveDecay into your PhysicsList. Then you can simply
 fire Sr90 as your primary particle via G4ParticleGun or 
 G4GeneralParicleSource. In default the decay of Y90 will be simulated 
 as well.  All beta products, i.e. electron, neutrino, residual 
 nucleus and gammas in the case of Y90, are tracked through the 
 simulation.
