None Scintillation Process Question

Hello, I have a question concerning how scintillation is handled in Geant.

If you have a NaI(Tl) crystal, for example, valence electrons promoted to the conduction band will by far be from the Iodine and Sodium atoms. Some of these occur near a Thallium dopant and these excitons "drift" toward the thallium atom and the electron hole pair will be transferred to the Thallium atom which will then de-excite and produce light. My question is, how is this process modeled in Geant? Does there just exist some probability of Thallium emission given by the fraction of thallium in the crystal, or is it something more complex?

Thanks for any insight.
